THREADING WELDING WIRE THROUGH THE
DRIVE MOTOR TO THE WELDING GUN
This Welder uses wire sizes ranging from 0.023" to 0.035" (0.6mm to 0.9mm).
To safely and correctly install the welding wire; follow the procedure in the
sequence outlined below:
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH!
This procedure requires that the Welder power be switched ON.
DO NOT make contact with the wire when the MIG Gun Trigger
is depressed.
1. Turn the Power Switch on the Upper rear Panel to the "OFF" position and unplug
the Welder from the power supply.
2. Using the included Contact Tip Wrench [N] Remove the Contact tip and Nozzle
from the end of the MIG Gun.
3. Make sure that the drive roller is installed in the proper position in accordance
with the wire size being used. As Described in "POSITIONING DRIVE ROLLER for
WIRE SIZE" section of these instructions.
4. Flip the Wire Tensioner outward, pivot it down and out of the way then pivot the
Tension Arm up away from the Drive Roller (FIG 11).
5. Pull out the welding wire from the wire spool carefully.
IMPORTANT NOTE: DO NOT let go of the wire or the entire spool could unravel.
6. Cut off the small piece of the curved segment at the front of welding wire and
straighten the welding wire approximately 3.0" long.
7. Thread the welding wire feeding from the underside of the spool and forward
through the Guide Tube then over the wire Drive Roller and into the Wire Feed
Hole (FIG 12).
8. Replace the Tension Arm and re-latch the Wire Tensioner back into place
(FIG 13).
9. Connect the Welder to a power supply and Turn the ON/OFF Switch at the upper
rear panel to the "ON" position. Set the Wire Speed Control to about 197 IPM.
10. With the gun pointed away from yourself and others, depress the trigger to begin
feeding wire.
NOTE: The Wire Tensioner may need to be set. To do so:
- Watch the drive roller to see if any slipping is occurring between the roller
and the wire. If so; turn the machine off, unplug it and tighten the Wire
Tensioner 1⁄4 turn and test again.
- Repeat the above step until wire is feeding smoothly with no binding or
slippage.
Once the wire exits the end of the MIG Gun, reinstall the contact tip and nozzle. Cut the
wire about 1/4" from the end of the contact tip.
