As aconsequence, the car bodyworkers have to substitute thetraditional mechanic tools formetal sheet cutting with plasmacutting systems, even because,now (and more and morefrequently from now on), theyhave to deal with the repairingof vehicle parts where thepresence of steels and specialalloys is very high.TELWIN offers the solutionto these problems with therange of plasma cuttingsystems TECNICA PLASMAand TECHNOLOGY PLASMAthat thanks to their invertertechnology are able to cutrapidly and without deformationthe widest types of steels, fromthe High Strength Steels(HSS) to the UltraHigh StrengthSteels (UHSS).Moreover, it isnot to forgetthe capacitygiven bythe invertertechnology,to operate on metal sheetsone next to the other withoutdamaging the lower ones.The models TECNICA PLASMA34 KOMPRESSOR andTECHNOLOGY PLASMA 54KOMPRESSOR make the repairwork further easy because theyhave a built-in compressor thateliminates the connection to anexternal compressed air powersource and grants the maximumautonomy to the end-user.INVERTER PLASMA FEATURES• User’s friendly• High precise cut• Low operating time• Operation on moreoverlapping platesTECHNOLOGY PLASMA 41TECNICA PLASMA 31TECHNOLOGY PLASMA 54 KOMPRESSORTECNICA PLASMA 34 KOMPRESSORMASTERMIG 400MASTERMIG 300MASTERMIG 270/2MASTERMIG 220/2TELMIG 200/2TELMIG 180/2www.telwin.comTECHNOMIG 225 PULSETECHNOMIG 220DIGITAL MIG 330DIGITAL MIG 220DIGITAL MIG 180TECHNOLOGY TIG 180 AC/DC-HF/LIFTcod. 988813TELWIN S.p.A. - Via della Tecnica, 3 - 36030 VILLAVERLA (Vicenza) ItalyTel. +39 0445 - 858811 Fax +39 0445 - 858800 / 858801e-mail: telwin@telwin.com http://www.telwin.com

TELWIN MAGAZINEautomotive special editionN. 1 2007THE TECHNOMIG RANGE: INTELLIGENT & MULTIFUNCTIONAL DESIGNED FOR THE AUTOMOTIVEThe best reply to all the requirementsduring MIG-MAG welding and MIGbrazing in the car body shop, a rangeof welding machines that grantsquality and performances on all therepair works.Designed specifically for operating onany kind of material present today inBATTERIES & TELWIN: BATTERY CHARGERS IN THE AUTOMOTIVEIn order to choose the battery chargerfit for your needs, it is necessary toknow first of all the structure and thebase composition of a battery, onconsideration of the wide offer of thebatteries available in the automotivesector.Structure of a batteryThe batteries commonly used in theautomotive are lead batteries with acidelectrolyte which are mainly composedby:- ELECTRODES (PLATES) made upof materials which take part to theelectrochimical reactions.- the ELECTROLYTE, solution ofsulphuric acid in which the plates areabsorbed and where the ions involvedin the electrochemical reactions arespread.The typologies of batteries present inthe market are classified accordingto the material composition of theirPLATES and to the structure of theELECTROLYTE.As regards the composition of thePLATES, besides the traditional alloy of12345GratePositive PlateNegative PlateDividing PartCellthe automotive sector, the invertrerwelding machines TECHNOMIG225 PULSE and TECHNOMIG 200allow for a strong saving in time andtherefore in the repair costs. The hightechnology of these products is wellintegrated with their easiness of usethanks to a series of built-in specificfunctions designed by TELWIN.TECHNOMIG 200 and 225 PULSE,thanks to the many synergicprograms stored in theirmicroprocessor, enable alsothe less expert user toset rapidly the weldingparameters by acting onone regulation only. Inthis way all operativematters of the bodyshop works are solvedin the most efficientway.The high resistancesteels (HSS, AHSS,UHSS), e.g. Boronsteel, stainlesssteel, aluminium,plated sheets,galvanized sheetsLead-Antimony, modern technologyhas allowed for the introduction ofother alloys such as Lead-Calciumand Lead-Calcium- Silver which arecharacterized by a low consumptionof the eletrolyte and a minimum rateof discharge.As regards the ELECTROLYTE, thebatteries are divided into:- WET, free or liquid electrolytebatteries, with (distilled water is filledin) or without maintenance (MF);- HERMETIC, immobilzed electrolytebatteries where the electrolyte canbe used either as gel (GEL) orabsorbed in glass fibers (AGM),without maintenance.TELWIN Battery ChargersWhile the quality of the batterydepends on the type of plates used,the composition of the electrolyte,just out of its physical-electricalfeatures, determines the choice ofthe battery charger.Therefore the hermetic GEL andAGM batteries, having a particularconstructive technology, need amonitoredcharging processthat onlysophisticatedelectroniccircuits are ableto control. Asa result theyrequire specificelectronic batterychargers whichWET batteries donot need.All TELWINbattery chargersare designedand realized forWETHERMETICare characterized by certain physicalcharacteristicts which requirea perfect control of the weldingparameters so as to grant a correctrepair work.To point out is the quality of theresults in the brazing process;TECHNOMIG 200 and 225 PULSEallow welding also on thin thicknesseswithout damaging the galvanized coverof the sheet and without unshapingit. In this way the oxidation danger isavoided and the work time is muchreduced.TECHNOMIG 225 PULSE canperform MIG PULSE welding on thinthicknesses with low heat transfer,absence of sparkles of meltedmaterial and deep penetration in thewelding pool.The great interest aroused by theseproducts, is a result also of theirflexibility of use, they are, in fact,multiprocess models for MIG-MAG/TIG/MMA welding and respond inan excellet manner to any operativerequest.WETLEADANTIMONYPbSnLEADCALCIUMPbCaLEADCALCIUMSILVERpbCaAgGELLEADCALCIUMPbCaAGMLEADCALCIUMPbCaTYPES OF BATTERIESFREE ELECTROLYTE•High consumption of the electrolyte•High self-discharge•Reduced consumption of theelectrolyte•Low discharge•Minimum consumption of theelectrolyte•Minimum self-dischargeGEL ELECTROLYTE•Hermetic construction•Maintenance free•Minimum self-dischargeIMMOBILIZED ELECTROLYTE•Hermetic construction•Maintenance free•Minimum self-dischargecharging free electrolyte WET batteries;the models NEVADA, ALPINE, LEADER,DYNAMIC, ENERGY, MOTOTRONIC,T-CHARGE, NEVATRONIC, AUTOTRONIC,NEVABOOST, DIGITRONY, DIGISTART,STARTRONIC, give excellent resultswith any WET battery, whether this has aLead-Antimony, or Lead-Calcium or Lead-Calcium-Silver electrolyte.As previously underlined, GEL and AGMbatteries require a specific chargebehaviour, that’s why TELWIN hasdesigned adequate electronic batterychargers such as: MOTOTRONIC,T-CHARGE, NEVATRONIC, AUTOTRONIC,DIGISTART, STARTRONIC. Theseproducts give excellent results in anysituation. It is clear that all electronicbattery chargers, thanks to the particularelectronic technology used, grant abetter control on the charge process incomparison with the traditional productsalso while charging WET batteries.TECHNOMIG FEATURES• Use in different welding processesfrom MIG-MAG welding and MIGbrazing to TIG-DC LIFT, from MMAwelding up to FLUX welding.• Great flexibility of use with a widerange of materials such as highresistance special steels, stainlesssteel, aluminium and galvanizedsheets• Digital control by microprocessor• High easiness of use thanks to theSYNERGIC function with 15 pre-setwelding programs and 10customized ones• Fit for use with SPOOL GUNENERGY ALWAYS AT HANDDo you need to start a vehicle and arein a difficult operative situation?
