5.4 Turning the power source on/off
Turn the power source on by turning switch (1) to the ”1” position. Turn the power source off
by turning the switch (1) 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, 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.
5.6 Overheating protection
The welding power source has overheating 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 overheating protection resets automatically when
the temperature has fallen.
5.7 Remote control unit
For more information about the operation of the remote control unit, see the instruction
manual for the control panel.
5.8 MIG/MAG and FCAW-S welding
An arc melts a continuously supplied wire. The weld pool is protected by shielding gas. For
MIG/MAG and FCAW-S welding, the power source is supplemented with:
• wire feed unit
• welding torch
• connection cable between power source and wire feed unit
• shielding gas bottle
5.9 MMA welding
MMA welding may also be referred to as welding with coated electrodes. Striking the arc
melts the electrode and its coating forms protective slag.
For welding with coated electrodes, the power source is supplemented with:
• welding cable with electrode clamp.
5.10 TIG welding
TIG welding melts the metal of the workpiece, using the arc struck from a tungsten electrode,
which does not melt itself. The weld pool and the electrode are protected by shielding gas.
For TIG welding, the welding power source is supplemented with:
• TIG torch with tungsten electrode and gas valve
• argon gas bottle
• argon gas regulator
