Connection of welding and return cable

There are two terminals on the power source, a positive terminal (+) and a negative
terminal (-), for connecting welding and return cables. Selected welding method and
type of used electrode determines to which terminal the welding and the return cable
should be connected to. Before welding make sure that cables are firmly attached to
the power source, and that return cable clamp is properly attached on the workpiece.
5.3

Turning the power source on/off

Turn the machine on by turning switch (1) to the "1" position. Turn the machine off by
turning the switch (1) to the "0" position. Regardless the mains supply is interrupted
abnormally or the machine 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.
5.4

Fan control

The power source has a time circuit, which keeps the fans running for 6.5 minutes
after welding has stopped, then 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 200 A, and at full speed for higher currents.
