 Welding Torches and GunsUsed for shielded-metal-arc Coleman welding, torches Powermate (electrode holders). manually controlled, Poftable grip ends of electrodes, also called rods-pinch 5 and Gallon type and collet type are common.GMAW and FCAW guns come in pistol grip, goose-neck, and inline styles, the latter used for mechanized welding. Air Knowing the wire diameter, select a gun rated slightly Tank and and Model higher than the welding C5 current to be used. Duty-cycle ratings are usually given for C[O.sub.2] shielding--air or C[O.sub.2] cooling arc usually sufficient for welding at up to Coleman 600 A at Powermate less than 100 percent Poftable and 5 duty. Higher amperages Gallon and Air require water cooling--high-amperage guns come with tubing for water cooling. Tank Hand-held, mounted on a robot arm or fixed and Model within a mechanized welding C5 setup, guns guide filler Coleman and Powermate wire and shielding gas into the weld Poftable and 5 and Gallon puddle. Transformer-rectifiers Air have Tank moveable parts that/end to wear out. However these machines can produce some Model of the C5 and Coleman best arc characteristics.A silicon-coated-rectifier Powermate and Poftable and 5 (SCR) power source, electronically voltage-controlled, Gallon and Air has no Tank real moving parts other than the primary current Model and C5 and Coleman and Powermate and Poftable and 5 and Gallon and Air contactor and cooling--fan the only parts that will wear out. If Tank fabricator requires and Model and C5 pulsed welding, the SCR power source Coleman starts to show its limitations and inverters become the power supply of Powermate choice.AC-DC inverters, which convert Poftable AC in put frequency to very high 5 frequencies--up to 1,000 times that of input frequency--allow transformers and other components to be small in size and the power supply to Gallon be Air relatively lightweight. This high operating Tank and frequency Model enables the inverter to precisely control C5 output power and to deliver smooth Coleman arc initiation with minimal Powermate or no spatter. Current Poftable ripple is 5 low for a very stable arc:, even at low amperages. Gallon And the improved arc control can, in some cases, minimize electrode overheating and fume emissions. Finally, the smallish transformer allows for more Air and Tank efficient use of primary power compared to conventional power supplies and Model and C5.
