Setting wire-feed pressure

NOTE!
This procedure requires the unit be powered ON. The gas does not need to be
connected for this procedure.
1. Turn power to the unit ON.
2. Start by making sure that the wire moves smoothly through the wire guide.
CAUTION!
It is important that the feed-pressure is not too high.
3. Adjusting for minimum roller pressure:
When you hold the welding torch approximately 6 mm (¼ in.) from the piece of wood
the wire-feed rollers should slip. If they don't reduce the tension on the wire by
adjusting the tension knob on the wire-feed assembly.
4. Adjusting for correct roller pressure:
If you hold the welding torch approximately 50 mm (2 in.) from the piece of wood, the
wire should be fed out and bend.
