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 "esca-
ping" 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.
