Weldmatic 175 [internal wirefeeder] - BJH

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
