6.2 Overheating protection
A thermal overload cutout protects against overheating. The cutout resets automatically
when the unit has cooled.
6.3 Inductance connection
Higher inductance produces a more flowing weld and fewer spatters. Lower inductance
produces a harsher sound and a sta le, concentrated arc.

7 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself attempts any work
in the product during the guarantee period in order to rectify any faults.
7.1 Inspection and cleaning
Check regularly that the power source is free from dirt.
The power source should e regularly lown clean using dry compressed air at reduced
pressure. More frequently in dirty environments.
Otherwise the air inlet/outlet may ecome locked and cause overheating. To avoid
this you can use an airfilter.
The airfilter is an accessory. Ordering num er can e found on page 14.
8 FAULT TRACING
Try these recommended checks and inspections before sending for an authorised service technican.
Type of fault Actions
No arc SCheck that the mains power supply switch is turned on.
SCheck that the welding current supply and return ca les are
correctly connected.
SCheck that correct current value is set.
SCheck to see whether the MCB has tripped.
Welding current is interrupted
during welding
SCheck whether the thermal overload trip has operated
(indicated y the orange lamp on the front).
SCheck the main power supply fuses.
Thermal overload trips
operate frequently
SCheck to see whether the air filters are clogged.
SMake sure that you are not exceeding the rated data for the
power source (i.e. that the unit is not eing overloaded).
Poor welding performance SCheck that the welding current supply and return ca les are
correctly connected.
SCheck that the correct current value is set.
SCheck that the correct welding wires are eing used.
SCheck the main power supply fuses.
