• Replacing the Wire Liner:
1. Fit the correct nipple
2. Remove Gas Nozzle and Tip Adaptor
3. Fit the wire liner in the hose package
4. Cut the wire guide to the correct length. During cutting, the welding
torch must be extended with the wire guide fully inserted into the rear
connector. Remove sharp edges of liner after cutting.
5. Re-fit the Tip adaptor and gas nozzle.
6. Fit the Torch on the machine.
• Gas Nozzle: There is a spatter-protector fitted inside the gas nozzle. This must
be in position during welding in order to prevent the welding spatter jamming
and thereby causing a short-circuit in the swan neck.
• Gas Protection: Several factors come into play for good gas protection. The
most important ones are:
1. Selection of Gas—Mixed Gas and Argon require a greater flow rate
than CO
2. Flow rate should be set as per requirement.
3. Welding Current—higher currents require greater gas flow.
4. Position of Welding joint—Vertical position requires greater gas flow.
5. Types of Welding joint—External corner joints require greater gas flow
than butt joints. Conversely, fillet joints require lesser gas flow.
6. Angle of Welding Torch to the joint—Angling the torch at less than 45°
may result in poor gas protection.
