Weldmatic 175 [internal wirefeeder] - BJH

Weldmatic 175Burn protectionThe welding arc is intense and visibly bright.Its radiation can damage eyes, penetratelight-weight clothing, reflect from lightcolouredsurfaces, and burn the skin andeyes. Burns resulting from gas-shielded arcsresemble acute sunburn, but can be moresevere and painful.Wear protective clothing - leather or heatresistant gloves, hat, and safety-toe boots.Button shirt collar and pocket flaps, andwear cuffless trousers to avoid entry ofsparks and slag.Avoid oily or greasy clothing. A spark mayignite them. Hot metal such as electrodestubs and work pieces should never behandled without gloves.Ear plugs should be worn when welding inoverhead positions or in a confined space.A hard hat should be worn when others areworking overhead.Flammable hair preparations should not beused by persons intending to weld or cut.Toxic fumesAdequate ventilation with air is essential.Severe discomfort, illness or death canresult from fumes, vapours, heat, or oxygendepletion that welding or cutting mayproduce. NEVER ventilate with oxygen.Lead, cadmium, zinc, mercury, and berylliumbearing and similar materials when weldedor cut may produce harmful concentrationsof toxic fumes. Adequate local exhaustventilation must be used, or each person inthe area as well as the operator must wearan air-supplied respirator. For beryllium, bothmust be used.Metals coated with or containing materialsthat emit fumes should not be heated unlesscoating is removed from the work surface,the area is well ventilated, or the operatorwears an air-supplied respirator.Work in a confined space only while it isbeing ventilated and, if necessary, whilewearing air-supplied respirator.Vapours from chlorinated solvents can bedecomposed by the heat of the arc (orflame) to form phosgene, a highly toxicgas, and lung and eye irritating products.The ultra-violet (radiant) energy of the arccan also decompose trichlorethylene andperchlorethylene vapours to form phosgene.Do not weld or cut where solvent vapourscan be drawn into the welding or cuttingatmosphere or where the radiant energycan penetrate to atmospheres containingeven minute amounts of trichlorethylene orpercholorethylene.Fire and explosion preventionBe aware that flying sparks or falling slag canpass through cracks, along pipes, throughwindows or doors, and through wall or flooropenings, out of sight of the operator. Sparksand slag can travel up to 10 metres from the arc.Keep equipment clean and operable, free ofoil, grease, and (in electrical parts) of metallicparticles that can cause short circuits.If combustibles are present in the workarea, do NOT weld or cut. Move the work ifpracticable, to an area free of combustibles.Avoid paint spray rooms, dip tanks, storageareas, ventilators. If the work can not bemoved, move combustibles at least 10metres away out of reach of sparks and heat;or protect against ignition with suitable andsnug-fitting fire-resistant covers or shields.Walls touching combustibles on oppositesides should not be welded on or cut. Walls,ceilings, and floor near work should beprotected by heat-resistant covers or shields.Model No CP122, Iss A 07/07

Weldmatic 1751 IntroductionGas Metal Arc Welding (G.M.A.W.) is an arcwelding process where a consumable wire isfed by motor driven feed rolls to a weldinggun, and where welding current is suppliedfrom the welding power source. The weldingarc is struck between the work piece andthe end of the wire, which melts into theweld pool. The arc and the weld pool areboth shielded by gas flow from the gun, orin the case of “self shielded” wires, by gasesgenerated by the wire core.2 ReceivingCheck the equipment received against theshipping invoice to make sure the shipmentis complete and undamaged. If any damagehas occurred in transit, please immediatelynotify your supplier.The process is very versatile in that byselection of the correct wire composition,diameter and shielding gas, it can be usedfor applications ranging from sheet-metal toheavy plate, and metals ranging from carbonsteel to aluminium alloys.The Weldmatic 175 has been designed tobe used with consumable wires in the rangefrom 0.6mm to 1.2mm diameter. The smallerwire sizes are used when welding at lowercurrents, such as sheet-metal applications.Increasing the wire diameter permits higherwelding currents to be selected.A common application of G.M.A.W. is forwelding Mild Steel. In this application, aMild Steel solid consumable wire such asAUSTMIG ES6 is used with a shielding gasof Carbon Dioxide, or Argon mixed withCarbon Dioxide. Alternatively, Flux-coredconsumable wires are available in both gasshielded, and ‘gasless’ self shielding types.Stainless steel and Aluminium can be weldedwith G.M.A.W. using the correct consumablewire and shielding gas.The Weldmatic 175 wirefeeder has beendesigned to feed a range of hard, soft, andflux-cored wires for the G.M.A.W. process.A compact motor with integral gear box iscoupled to a two roll drive assembly formingthe basic component of the wirefeeder. Themotor is controlled by an electronic speedcontrol which provides speed regulation.Model No CP122, Iss A 07/07

Operators Manual5 InstallationConnection to Electrical Mains PowerSupplyThe Weldmatic 175 is factory fitted with a3 metre, 3 core 30/0.25 Heavy Duty PVCmains power supply cable with moulded 3pin, 15 Amp, Single Phase plug.A 15 Amp plug and socket is recognisable bya wide Earth pin. Power Supply authoritiesrequire that equipment fitted with a 15 Ampplug shall ONLY be connected to a 240 Volt,15 Amp power point. DO NOT modify theplug.The minimum capacity of the mains wiringand power outlet supplying a welder isselected according to the effective primarycurrent of the equipment. The effectiveprimary current for the Weldmatic 175 is12 Amps.The minimum recommended mains circuitbreaker rating for a Weldmatic 175 is16 Amps. Note : Due to normal variationsof sensitivity, the tripping time of some 16Acircuit breakers may limit the duty cycleavailable from the Weldmatic 175. A higherrated circuit breaker can be selected, but themains wiring capacity must be rated to suit.The current rating of the mains cabledepends on cable size and method ofinstallation. Refer to AS/NZS 3008.1, Table 9.If it becomes necessary to replace the mainsflexible supply cable, use only cable withcorrect current rating. Access to the supplyterminals is gained by removing the powersource side panels.The replacement cable must be fitted andretained in the same manner as the original.Output Voltage PolarityThe design of the Weldmatic 175 allowsselection of the output voltage polarity.Positive WireG.M.A.W. with solid consumable wires iscarried out with the work piece Negative andthe welding wire Positive.To setup for this condition, connect the‘WORK’ lead plug into the (-) output socketon the Power Source, and the ‘WELDING’lead from the power source into the (+)socket, as in Figure 2.Negative WireFig 2 Positive WireFig 3 Negative WireTo gun cableTo work clampSome ‘self-shielded’ flux cored consumablewires are operated with the work piecePositive and the consumable wire Negative.Refer to the manufacturers data for theparticular consumable wire to be used.To setup for this condition, connect the‘WORK’ lead plug into the (+) output socketon the Power Source, and the ‘WELDING’lead from the power source into the (-)socket, as in Figure 3.To work clampTo gun cableQuality • Reliability • Performance

Weldmatic 175Fitting the gas cylinderPlace the gas cylinder on the tray at therear of the optional welder trolley (if using).Retain the cylinder with the chain provided.Fit the gas regulator to the cylinder. DO NOTapply grease or oil to these joints.Fit the end of the gas inlet hose from theback of the power source to the connectorsupplied with the gas regulator, and securewith the clamp also supplied.Fitting The Gun and Cable AssemblyThe supplied gun/cable assembly is equippedwith a ‘Euro’ wirefeeder connector whichincorporates all required connection pointsfor welding current, shielding gas and gunswitch control.To attach the gun/cable assembly tothe wirefeeder mechanism, engage themating parts of the male and female Euroconnectors, then rotate the locking ringclockwise to firmly secure the connection.Fitting the Consumable WireThe quality of the consumable wiregreatly affects how reliably a gasmetal arc welder will operate. For bestresults when welding mild steel, werecommend quality WIA AUSTMIG ES6.Dirty, rusty or kinked wire will not feedsmoothly through the gun cable andwill cause erratic welding. Deposits fromthe wire will clog the gun cable linerrequiring it to be replaced prematurely.5 kg SpoolsPlace the spool of welding wire onto thespool holder. The location pin should matewith a hole provided on the wire spool body.Fit the spool retaining ‘R’ clip supplied. Checkthe adjustment of the spool adjuster, whichshould be set to prevent over run of the wirespool at the end of a weld, without undulyloading the wirefeed motor.1 kg SpoolsRemove the adjustor knob, spring, washerand 5 kg spool holder. Leave the 5 kg spoolholder in a safe place (ie inside the welder).Fit the 1kg wire spool directly onto the spoolaxle. Fit the washer, spring and adjustor knoband tighten the adjustor knob fully.Feeding the Consumable WireAt the wirefeed assembly, release thecompression screw by swivelling it outwards.This allows the top roller arm to spring to theopen position. The end of the welding wirecan now be passed through the inlet guide,over the bottom driven roller, and into theoutput wire guide tube. Check that the driveroll groove is correct for the wire in use. Theappropriate size is stamped on the visibleside of the installed roller. Check also thatthe correct size contact tip is fitted at the gunend. Feed roller and tip details are shown inSection 11 of this manual.Return the top roller arm to the closedposition and adjust the compression screw toprovide sufficient clamping of the drive rollto achieve constant wirefeed. Do not overtighten.With the equipment energised, operate thegun switch to feed wire through the guncable.Compression screwTop roller armGroove sizeModel No CP122, Iss A 07/07

Operators Manual6 Normal Welding SequenceWeld StartClosing the welding gun switch initiates thissequence of events:• The gas valve is energised and gas flowcommences;• The power source contactor is initiated.Welding voltage is applied between thework piece and the consumable wire.• The wire drive motor is energised.• The wire touches the work piece, and thearc is established.Weld EndReleasing the gun switch initiates thissequence of events:• The wire drive motor is de-energised, andis dynamically braked to a stop;• The welding transformor is de-energisedand welding current stops.• The gas valve is de-energised and theflow of shielding gas ceases.7 Basic Welding InformationChoice of Shielding GasThe choice of shielding gas is largelydetermined by the consumable wire tobe used. Many proprietary shielding gasmixtures are available.The recommended shielding gases for usewith the Weldmatic 175 are:• Mild Steel Argon +5 to 25% CarbonDioxide;• Aluminium Argon;• Stainless Steel Argon + 1 to 2%Oxygen.Consult your gas supplier if more specificinformation is required.Shielding Gas Flow RateIn G.M.A. welding, one function of theshielding gas is to protect the molten weldpool from the effects of oxygen in theatmosphere. Without this protection theweld deposit becomes ‘honeycombed’ inappearance, an effect which is described asweld porosity.In draft-free conditions the gas flow raterequired to give adequate protection istypically 10-12 litres/min. In situations wheredrafts cannot be avoided, it may be necessaryto increase this rate up to 20 litres/min, and/or to provide screening of the work area.Weld porosity can also be caused by airentering the gas stream through a damagedhose, loose gas connection, or fromrestriction in the nozzle, such as from excessbuild-up of spatter.When welding aluminium, particular caremust be taken with all aspects of shieldinggas delivery and workpiece preparation inorder to avoid weld porosity.10Quality • Reliability • Performance

Weldmatic 175Establishing a Weld SettingOnce the consumable wire type, wire sizeand shielding gas have been chosen, the twovariables that are adjusted in order to obtaina the desired weld setting are;• Wirefeed speed,• Welding arc voltage.The Weld Setting Charts in Figure 4 can beused to preset the machine for an approximatewelding current. For each of the combinationsof voltage control switch settings, there is arange of valid wirespeed settings.The wirefeed speed determines the weldingcurrent; increasing the speed increases thecurrent, and decreasing it decreases current.The selected wirefeed speed must bematched with sufficient arc voltage; a speedincrease requires an increase of arc voltage.If the voltage is too low the wire will stuband stutter, and there will not be a steadyarc. If the voltage is too high the arc will belong with metal transfer occurring as a seriesof large droplets.Important: Do not operate the VoltageControl switches during welding.The weld setting should be chosen to suit theapplication and the thickness of the metal tobe welded. It is important to check that thedeposited weld provides sufficient strengthto suit the application.A “good” weld will have the characteristicsillustrated in Figure 5. The weld has penetratedinto the parent metal, fusing the root of thejoint where the two plates meet, and the weldblends smoothly into the side walls.A “bad” weld is shown in Figure 6. The weldhas not penetrated the joint root, and thereis poor side wall fusion. This lack of fusionwould normally be corrected by increasingthe arc voltage, or by increasing bothwirefeed speed and arc voltage to achieve ahigher current weld setting.Gun PositionFig 5 “Good” WeldFig 6 “Bad” WeldFor “down hand” fillet welding with gasshielded solid wires, the gun is normallypositioned as shown in Figure 7a below, withthe nozzle end pointing in the direction oftravel.For “down hand” fillet welding withgasless flux cored wires, the gun is normallypositioned as shown in Figure 7b below,with the nozzle end pointing away from thedirection of travel, referred to as ‘dragging’the weld. Gasless flux cored wires should beModel No CP122, Iss A 07/07 13

If the machine is operated at areduced welding current, a higher duty cycleis available. The diagram below illustrates theappropriate duty cycle rating for the range ofwelding currents available from the 175, andso allows the maximum welding time per 10minute period to be determined.The power source is protected by in builtover temperature protection devices. Thesewill operate if the machine is operated inexcess of its current and duty cycle rating. Ifthis occurs, the fan will continue to run, butthe machine will not deliver welding currentuntil the unit has cooled sufficiently.Fig 7b Gasless Flux Cored WiresFig 8 Duty Cycle RatingFig 7c Wire Stickout for Gasless Welding14Quality • Reliability • Performance

Weldmatic 1758 General MaintenanceBefore removing the equipmentcover, ENSURE that the equipmentis disconnected from the mainspower supply. When the equipmentis energised LETHAL VOLTAGES arepresent on the electrical componentsenclosed.DustCare should be taken to prevent excessivebuild-up of dust and dirt within the weldingpower source. It is recommended that atregular intervals, according to the prevailingconditions, the equipment covers be removedand any accumulated dust be removed by theuse of dry, low pressure compressed air, or avacuum cleaner.WirefeedIn order to obtain the most satisfactorywelding results from the G.M.A.W. process,the wirefeed must be smooth and constant.Most causes of erratic wirefeed can be curedby basic maintenance. Check that the:1 Feed rolls are the correct size and type forthe wire in use. Check also that the drivegroove is aligned with the wire (referpage 9), and that the groove is not worn;2 Gun cable liner is clear of dust and swarfbuild-up. When replacement becomesnecessary, fit only the correct liner (seepage 24). The build-up of dust can beminimised by regular purging of the linerwith dry compressed air. This may beconveniently done each time the wirespool is replaced;3 Welding tip is free of obstructions suchas spatter build-up. Ream out the tipbore with a suitable size oxy-tip cleaner.Replace the welding tip as it becomesworn;4 Feed roll pressure is not excessive. Thepressure should be just sufficient to feedthe wire evenly. Excessive pressure willdeform the electrode wire and makefeeding more difficult;5 Consumable wire spool holder rotatessmoothly and that the braking action isnot excessive. The spool should only havesufficient braking to prevent over runwhen the motor stops. This also may beconveniently checked each time the wireis replenished;7 Welding wire is straight and free ofbuckles or ‘waviness’. To check, remove2 or 3 metres of wire from the spool.Clamp one end in a vice or similar, thenholding the other end pull the wire outstraight. Look down the length of thewire, any buckles will be obvious. Buckledwire is extremely difficult to feed reliablyand should be replaced;8 Welding wire is free of surface rust.Replace if rust is evident.Model No CP122, Iss A 07/07 15
