4. OPERATION DISTURBANCES

4.1 THE MOST USUAL OPERATION DISTURBANCES ARE AS FOLLOWS

Arc is not ignited:

• Cable is loose or there is a bad connection.

• Electrode of torch is highly oxidized (grey). Sharpen again lengthwise. Check that post

gas time is long enough. Check ignition by using pre-gas e.g. by 4-function operation of

torch.

• There are impurities in shielding gas (moisture, air).

• Protective hose or another insulation of torch is broken and ignition spark is “escaping”

from elsewhere than from electrode of torch.

• Torch is wet.

• At low current is used too big or blunt electrode.

Gas shielding is bad (weld pool “is boiling”, electrode will be oxidized)

• There are impurities in shielding gas (moisture, air).

• There are impurities in base material (rust, base coat, grease).

• On gas nozzle or housing of tightening bushing has stuck “spatter”.

• Net of gas lens is damaged.

• There is too much draught at welding place.

• Note! With gas lens equipment you get a more balanced gas ow than with normal gas

nozzle equipment.
