5.3 Connection of welding and return cable
The power source has two outputs, a positive terminal (+) and a negative terminal (-), for
connecting welding and return cables.
Connect the return cable to the negative terminal on the power source. Secure the return
cable's contact clamp to the work piece and ensure that there is good contact between the
work piece and the output for the return cable on the power source.

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. The duty cycle is valid for 40°C (104°F).
5.4 Turning the power source on/off
Turn the power source on by turning switch (2) to the ”1” position. Turn the power source off
by turning the switch (2) to the ”0” position. Regardless the mains supply is interrupted
abnormally or the power source is switched off in the normal manner, the welding data will be
stored, so it will be available next time the unit is turned on.
5.5 Fan control
The power source has a time circuit, which keeps the fans running for 6.5 minutes after
welding has stopped, after that the unit switches to energy-saving mode. The fans start again
when welding begins. The fans run at reduced speed for welding currents up to 150 A, and at
full speed for higher currents.
CAUTION!
The fans may start at any time to protect the power source from overheating.
5.6 Thermal protection
The welding power source has thermal protection circuit that operates if the internal
temperature becomes too high. When this occurs the welding current is blocked and a fault
code is displayed on the control panel. The thermal protection resets automatically when the
temperature has fallen within normal operation temperature.
