4.2 Wire Feed Set-up

The feed roller is fitted with four pilot grooves for wire diameters 0.6/0.8/1.0/1.2 mm.

To adapt the feed roller to the wire size used, first release the tension roller from the feed roller by pushing the lever back.

For 1.0 or 1.2 mm wire the corresponding outer groove is required. Place spacer washer onto drive shaft, then feed roller so that the required groove size is in line with the wire intake of the central goupling. For 0.6 or 0.8 mm wire the inner grooves are required. Place feed roller first onto shaft, followed by the spacer washer. After spacer and feed roller have been mounted as required secure in place with the washer, serated lock washer and screw. If required, the two nuts on the central coupling's wire intake can be loosened and its position centered to the groove.

Return the tension roller onto the feed roller an set to required tension by means of the setting screw.

4.3 Feeding the Wire into the Torch

Place the wire through the spiral guide tube across the feed roller into the central coupling's wire intake. Bring tension roller in position and set tension.

Unscrew the gas shroud from the swan neck by turning clockwise, contact tip by turning counter-clockwise. Switch the machine on, set wire feed speed to lowest speed and press the torch's trigger switch until the wire protrudes approx. 2.5 cm/1 in. from the swan neck. Replace contact tip and gas shroud.

Please note that all machines as standard fitted for 0.6; 0.8 and 1.0 mm electrode wire. If a wire of a different diameter is to be used, the contact tip must be exchanged against on of matching size and the feed roller installed with the corresponding groove size opposite the wire intake.

5 Welding Stainless Steel and Aluminium

This MIG welding machine is factory set for welding low-carbon steel. Use a mixed gas (e.g. Ar 99.988 %).

Setting of Wire Feed Speed

Fine tuning of setting during welding is actually carried out.The feed speed is correct when the arc burns with a steady hum.
