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? Yourbatteries are down and you find yourselfon the road, in a building yard, in anisolated place where it is difficult orimpossible to have a mains suppliedgenerator?START PLUS 2824 and 1524 areTELWIN’s answer to all your needs!START PLUS 2824 and 1524 infact, are handy, professional 24/12Vstarters with maximum startingcurrent of 2200A e 1500A accordingly;designed for the automotive sector andin particular for trucks, bulldozers, vans,autos, etc. They have a maintenancefree hermetic battery with AGMtechnology and can be used more thanonce before being recharged. They areequipped with a 12V output as powersource for use in emergencies.www.telwin.com
