WHAT IF THE INVERTER DOESN’T WORK?

The welder doesn’t switch-on: check the mains connection and the switch position (1).

Irregular electrode welding:

Check correct connection of the cable holder and earth clamp according to the electrode being used.

Check that the welding current is appropriate for the electrode and the piece to be welded.

Check that the electrodes are not wet or damaged.

Check that the weld piece is not excessively dirty, greasy, etc.

Check that the earth clamp is well connected to the weld piece.

The welder doesn’t generate the power required:

Check that the mains voltage is between 210V-250V (even during welding)

If extension cables are used, make sure that they conform to the table on page 8.

 In TIG welding

The torch spatters during welding:

Check that the torch and earth are correctly connected.

Check that gas is present and that the flow is sufficient.

Check that the weld piece is not greasy or dirty.

Check that the weld piece isn’t composed of alloys incompatible with the power source used.

Check that the electrode is the right colour for the material to be welded.

Check if too high a current setting is being used.

Duty Cycle too short:

Check that the fan is turning.

Check if the fan is blocked and that air circulates from the air grids.

Check if the working environment is too hot.
