Roll Pressure Adjustment
Before welding the pressure roll will need to be tightened against the
wire sat in the groove of the two feed rolls.
To adjust;
•
Turn the pressure adjustment knob on the side of the torch in
the clockwise direction. Turn one, two or three times to load up the
pressure on the rolls.
• If during welding the rolls appear to be loosing grip on the wire, add more
pressure to the rolls by additional clockwise turns on the adjustment knob.
Do not over tighten as this may damage the wire and cause excessive debris build
up in the drive unit.
Identifying drive balance condition:
With the pressure roll slackened off , watch the torch pull drive roll rpm relative to
the wire feed speed.
If the wire is moving faster
than the roll rotates, this is an
“Under” speed condition which
may lead to the wire tangling
and nesting at the back of the
rolls.
If the wire is moving slower
than the roll rotates, this is
an “Over” speed condition
leading to wire stretching and
excessive debris build up in
the drive chamber.
The ideal condition is a slight
over speed condition. Enough
speed to pull on the wire but
not too much that the rolls skid
excessively over the wire and wearing.
