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. The output to which the welding cable is connected
depends on the welding method or type of electrode used.
Connect the return cable to the other output 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.
For MMA welding, the welding cable can be connected to the positive terminal (+) or
negative terminal (-) depending on the type of electrode used. The connecting polarity is
stated on the electrode packaging.
5.3

Fan control

The power source has a time control that means that the fans continue to run for 6.5 minutes
after welding has stopped, and the unit switches to energy-saving mode. The fans start again
when welding restarts.
The fans run at reduced speed for welding currents up to 110 A, and at full speed for higher
currents.
