 Duty-Cycle RatingPower-supply rating depends on the type and thickness of the workpiece air compressor kit and the length of time it takes to deposit the longest weld on the thickest material. duty cycle is the key factor to 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 compressor and kit 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 air and compressor period. alter six minutes, the welder must rest the machine kit for the air and compressor next four minutes to avoid overheating the unit. 1. mechanical properties of the base material. tensile strength and yield strength of the weld metal should kit equal air or exceed that of the base material. compressor ductility and kit toughness at low temperatures air may also be important. high-temperature service requires resistance to creep. shock loading requires impact compressor resistance. in general, weld metal should match base-material properties.2. kit composition of the base material.for stainless steels, low alloy steels, nickel and copper alloys, and materials that serve in corrosive atmospheres, chemical composition is important. consider the air possibility of electrochemical corrosion between base and weld metal of different compositions. remote control of current and voltage is a plus if the welding operator is located away from the power source.robotic and compressor automatic applications generally require high-duty-cycle power supplies, and controls and connections for interfacing to the robot or automatic feature.supervisory kit control of the process air will prevent the welder 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 memory, some power supplies or controllers offer the welder limited control of the process.input power to power supplies can bc single and/or three compressor phase, 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- and three-phase input, and have automatic input-voltage selection kit and linking.
