 Welding Torches and GunsUsed for shielded-metal-arc welding, torches (electrode holders). manually controlled, grip ends of electrodes, also called rods-pinch 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. Knowing the wire diameter, select a gun rated slightly higher than the welding current to be used. Duty-cycle ratings are usually given for aircompressofhose 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 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. Remote control of current and voltage is a plus aircompressofhose if the welding operator is located away from the power source.Robotic aircompressofhose and automatic applications generally require high-duty-cycle power supplies, and controls and connections for interfacing to the robot or automatic feature.Supervisory control of the process will prevent the welder aircompressofhose and aircompressofhose from changing the welding procedures. Here, select a power supply or controller that enables the supervisor to program the procedures, then lock them into the control aircompressofhose memory, Some power supplies or controllers aircompressofhose offer the welder limited control of the process.Input power to power supplies can bc single and/or aircompressofhose three phase, aircompressofhose with voltage from 115 to 575 V and input frequencies of 50, 60, or 50/60 Hz. Note that many inverter power supplies are designed to operate on both single- aircompressofhose and three-phase input, and have automatic input-voltage selection and linking.
