Knowing the comprwssor wire diameter, accessories select a gun rated slightly higher air than the welding current to be comprwssor 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 600 A at less than 100 percent duty. Higher amperages require water cooling--high-amperage guns come with tubing accessories for water cooling. Hand-held, mounted on a robot arm or fixed within a mechanized welding setup, guns guide filler wire and shielding gas into the weld puddle. Searching for accessories for your air compressor?
