Standard duty cycle for TIG welding measured according to German quality standard DIN EN 6097 -1 at 0° C ambient temperature Duty cycle 100 % ( DC / AC/DC ) 220 A /190 A 270 A /2 0 A 220 A / 210 A 250 A 250 A 360 A 380 A. 5) DEEP CYCLE BATTERIES What is the difference between deep cycle batteries and starting batteries? Unfortunately, the term Deep Cycle has been overused by the battery industry as a sales tool to imply a heavy-duty product. Requires compatible iPhone and data plan rates apply. (30% of 10 minutes is 3 minutes) Since most of the time I am welding on a setting well below 130 amps, the machine does not heat up as fast and will weld longer than the duty cycle rating before needing to cool down. However, many people do not seem to understand the difference and their relationship. Voltage in welding circuit as measured at the welding arc, is a function of. The gun heats up in just 6 seconds and features a fingertip trigger with a dual-output selector. We can report duty cycle in units of time, but usually as a percentage. The specifications are certified with a 100% Duty Cycle. Duration of the active part of the cycle. '2 The noise levels herein stated are the averaged value of the measured values of four directions of 7 meters length under non-loaded condition. Duty cycle is a welding equipment specification which defines the number of minutes, within a 10 minute period, during which a given welder can safely produce a particular welding current. Miller 211 rated is 150A at 30% duty cycle welding range is 30-210A. Does not include starting times or when the cooling load is too small, in which case the compressor may cycle on and off.
