CHOOSING A POLARITY
Polarity +
Gas-shielded MIG/MAG welding generally
requires positive polarity.
In any case, refer to the wire manufacturer's recommendations for the choice of polarity for your MIG-MAG torch.
GAS SUPPLY
- Fit a suitable pressure regulator to the gas cylinder. Connect it to the welding station with the pipe supplied. Attach the two hose clamps to prevent
leaks.
- Ensure that the gas cylinder is held securely in place with a chain attached to the power source.
- Set the gas flow rate by adjusting the dial on the pressure regulator.
NB: To adjust the gas flow rate more easily, use the rollers on the motorised spool by pulling the trigger on the torch (loosen the brake wheel on the
motorised reel so that no wire is drawn in). Maximum gas pressure: 0.5 MPa (5 bar).
This procedure does not apply to welding in «No Gas» mode.
