6.2
Start
When switched on, the indicator lamps are checked for 2 seconds. Normally, if the
power source has not overheated, it should start to work in idle mode, which is
indicated by the supply-ON lamp flashing. The fan stops.The fan starts once welding
starts.
6.3
Overheating protection
The power source has 2-step control of the fan speed and overheating protection. If
the temperature crosses the threshold point, the fan starts to operate with increased
speed. If the internal temperature becomes too high, the welding is interrupted and
disabled. This is indicated by the orange indicating lamp on the front of the unit being
permanently lit. The unit resets automatically once the temperature drops.
6.4
Idle mode
The machine has an idle mode. The fan switches off 5 min after welding has finished
or 5 min after running at a decreased speed without welding. Once the fan has
switched off, the power-supply lamp on the front panel flashes.
6.5
Inductance
Higher inductance produces a more flowing weld and less spatter. Lower inductance
produces a harsher sound and a stable, concentrated arc.
7
MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Supplier warranty is void if customer attempts any work on product during the
warranty period.
7.1
Inspection and cleaning
Power source
Check regularly that the power source is free from dirt.
The power source should be regularly blown clean using dry compressed air at reduced
pressure, see page 47. This should be done more frequently in dirty environments.
Otherwise the air inlet/outlet may become blocked and cause overheating. To avoid
this you can use an air filter.
The air filter is an accessory. The order number can be found on page 55.
