Installation
Micro Wire Feed (MIG)
CAUTION • Turn OFF and disconnect the welder
before starting the micro wire feeding operation.
• Open the micro wire feeding mechanism moving the
block / tension knob (A) downwards and front. The
pressure rod (B) will open uncovering the feeding rod (C).
• Release the micro wire from the spool and cut any bent,
damaged or burr portion at the end of the micro wire.
Keep the micro wire tension at all times to prevent
unrolling the spool.
• Straighten approximately 1.7" of micro wire and push
lightly through the feeding mechanism.
• Double check the micro wire is aligned with the notch
that suits the feeding rod diameter (D) This is important to
allow the micro wire to be pushed right. The feeding rod
has two notches. For 0.023" and 0.031" wires. This welder
includes an additional feeding rod for 0.031" and 0.039"
wires. To select which notch to use turn the retainers (E)
and remove them. The selected notch size is shown in the
feeding rod side (F). If you need using the other notch,
remove carefully the feeding rod and turn it around (G).
Remember that the notch to select is always the one farthest
away from the knob.
• Turn the pressure rod back into the original position and
secure lifting the blocking / tension knob. Turn the tension
knob into a medium position, for example, between 2
and 3.
• Hold the torch to remove the nozzle tip (H) and unscrew
carefully.
• Then, unscrew the contact nozzle (I) to remove it and
release the torch outlet.
• Check the welder switch is in the OFF position and the
grounding clamp is away from the torch tip.
• Connect the welder to the power supply and turn ON the
welder switch.
• Unroll completely the torch cable to make it as straight
as possible and press the micro wire feeding button (J) in
the control panel. The micro wire (K) will start being fed
through the cable and the torch. Have the micro wire
sticking out 4" approximately through the torch outlet.
• Turn OFF the welder and disconnect from the power
supply.
• Slide the contact nozzle over the micro wire and screw it
in place again.
• Slide the nozzle tip through the micro wire and screw
carefully in the torch outlet.
