PUSH-PULL TORCH QTLB-24D, QTLB-36D: How to Feed Welding Wire
a) Disconnect Power to the MIG/MAG equipment.
b) Ensure the Drive Roll in the MIG/MAG equipment, and PUSH-PULL Torch are marked with the
same diameter size as the
Welding Wire
you are about to feed thru the PUSH-PULL Torch.
c) Remove the
Nozzle (1)
using a twisting pull action and unscrew the
Contact Tip (2)
.
d) Fit the
Welding Wire
Spool as described in the MIG/MAG equipment operating manual.
e) Connect the PUSH-PULL Torch per in Section 6.03 then connect Power to the MIG/MAG
equipment.
f) With the PUSH-PULL Torch laying straight on the floor.
g) Depress the
Torch Trigger Switch (5)
to slowly feed the
Welding Wire
while pushing down
on the
Pressure Roll Release Button (4)
to let the
Welding Wire
pass over the
Drive Roll (3)
then release the
Torch Trigger Switch (5)
and the
Pressure Roll Release Button (4)
.
NOTE 2:
Refer to SECTION 8
TROUBLESHOOTING on Page 37 if the
Welding Wire
tangles
(Birds Nest) at the MIG/MAG equipment Drive Roll OR the PUSH-PULL Torch Drive Roll.
h) Depress the
Torch Trigger Switch (5)
again to slowly feed the
Welding Wire
75 mm (3 in.)
past the
Swan Neck
then release the
Torch Trigger Switch (5).
i) Fit the
Contact Tip (2)
, and
Nozzle (1)
to the PUSH-PULL Torch.
j) Before you start welding, test the PUSH-PULL Drive Roll Pressure is sufficient to feed the
welding wire:
i. Point the PUSH-PULL Torch at 60 degree and 100mm (4 in.) from a flat non-conductive
material, e.g. wood, on the floor.
ii. Depress
Torch Trigger Switch
(5)
to feed
Welding Wire
on to the flat non-conductive
material, e.g. wood.
iii. If the
Welding Wire
slips on the PUSH-PULL Drive Roll (
Welding Wire
does not feed
constantly from Torch), then adjust
Pressure Arm Screw (6)
by
rotating the
Pressure
Arm Screw (6)
using a screwdriver
:
- Counter-clockwise direction increases The Pressure Arm force to the Drive Roll. In-
creased Pressure Arm force on the Drive Roll can cause the
Welding Wire
to deform
producing metal fragments which clogs the Liner in the
Swan Neck
and can produce
poor wire feedability.
- Rotating in a clockwise direction reduces the Pressure Arm force to the Drive Roll.
Reduced causes the
Welding Wire
to slip on the Drive Roll and can produce an incon-
sistent welding.
iv. If the
Welding Wire
slips on the MIG/MAG equipment Drive Roll (
Welding Wire
does
not feed constantly from Torch) then adjust the Pressure Arm force on the Drive Roll as
described in the MIG/MAG equipment operating manual.
