Again the importance of smooth consistent wire feeding during MIG welding cannot be emphasized enough.
The correct installation of the wire spool and the wire into the wire feed unit is critical to achieving an even and consistent wire feed. A high percentage
of faults with MIG welders emanate from poor set up of the wire into the wire feeder. The guide below will assist in the correct setup of your wire feeder.
NOTE: VIPER MIG 120 is not suitable to weld Aluminium as it is a Synergic Welding Machine programmed for Solid Mild Steel wire and Flux Cored (Gasless) wires only.
(1)
Remove the spool retaining nut.
(4)
Snip the wire carefully, be sure to hold the wire to
prevent the spool uncoiling. Carefully feed the wire into
the inlet guide tube of the wire feed unit.
(7)
Press and hold the Torch Trigger to feed the wire
down the torch cable through to the torch head.
(2)
Note the tension spring adjuster and spool locating
pin.
(5)
Feed the wire through the drive roller and into the
outlet guide tube of the wire feeder.
(8)
A simple check for the correct drive tension is to
bend the end of the wire over hold it about 100mm
from your hand and let it run into your hand, it should
coil round in your hand without stopping and slipping
at the drive rollers, increase the tension if it slips.
(3)
Fit the wire spool onto the spool holder fitting the
locating pin into the location hole on the spool. Replace
the spool retaining nut tightly
(6)
Lock down the top pressure roller and apply
a medium amount of pressure using the tension
adjustment knob
(9)
The weight and speed of the wire spool turning
creates an inertia that can cause the spool to run on
and the wire loop over the side of the spool and tangle.
If this happens increase the pressure on the tension
spring inside the spool holder assembly using the
tension adjustment screw.
