2.3 Duty cycle and Over-heat
The letter “X” stands for Duty Cycle, which is
defined as the portion of the time a welding machine
can weld continuously with it’s rated output current
within a certain time cycle (10 minutes).
The relation between the duty cycle “X” and the
output welding current “I” is shown as the right

figure. If the welding machine is overheating, the IGBT
output welding current OFF and light the over-heat pilot lamp on the front panel. In that case, the
machine should not be welding for 10-15 minutes to cool down with the fanrunning. When
operating the machine again, the welding output current or the duty cycle should be reduced.
