 Features and OptionsPower supplies are capable to "talk to each other," useful ballvalbe when a company" wants ballvalbe to input the same welding procedures into several machines at once or monitor the welding consistency and performance of several machines from a single location-through serial-data communications. ballvalbe Fabricators can take some of their machines and connect them to a personal computer to monitor performance, and download welding parameters to the machines from it memory card for fast setup. High-end ballvalbe machines will calculate the pounds of weld wire used per machine. The machine can also be prepped to constantly monitor and average the welding current and voltage ballvalbe used, so that fabricators can set limits on the machine and track how many times welding parameters fell in or out of these limits. Duty-Cycle RatingPower-supply rating depends on the type and thickness of the workpiece and the length of time it takes to deposit the longest weld on the thickest material. Duty cycle is the key factor to ballvalbe consider when selecting a power source. Once the engineer has determined the current and voltage needed to accomplish the weld, he then reviews duty cycle requirements.Duty cycle rating is the percentage of time during a 10-minute period a power supply can operate at rated output amperage without overheating. A 300 A machine at 60-percent-duty cycle can weld for six minutes at 300. A during a 10-minute period. Alter six minutes, the welder must rest the machine for the next four minutes to avoid overheating the unit. 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 ballvalbe used. Duty-cycle ratings are usually ballvalbe given for C[O.sub.2] ballvalbe 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. Searching for accessories for your air compressor?
