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 to the left. 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 18" 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. To
select which notch to use turn the knob (E) and remove
it. The 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 (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.
• Set the micro wire speed knob into the 5 or 6 position.
• 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 through the micro wire and screw
carefully in the torch outlet.
