Connect the return cable to the other output on the power source. Secure the return cable's
contact clamp to the workpiece and ensure there is a good contact between the workpiece
and the output for the return cable on the power source.
For SMAW welding, the welding cable can be connected to the positive terminal (+) or
negative terminal (-), depending on the type of electrode used. The connection polarity is
stated on the electrode packaging.

Duty cycle
The duty cycle refers to the time, expressed as a percentage of a ten-minute period, during
which you can weld or cut at a certain load without overloading. The duty cycle is valid for
104°F (40°C).
5.4 Turning the mains 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.
