Duty cycle

The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or
cut at a certain load without overloading.

5.4

Turning the power on/off

Turn on the mains power by turning switch to the ”I” position, see 1 in the picture above.

Turn the unit off by turning the switch to the “O” position.

Whether the mains power supply is interrupted or the power source is switched off in the
normal manner, the welding data will be stored so it is available the next time the unit is
started.

CAUTION!

Do not turn off the power source during welding (with load).

5.5

Fan control

The power source has a time control, this means that the fans continue to run for 6.5 minutes
after welding has stopped, and the power source switches to energy-saving mode. The fans
start again when welding restarts.
