Setting the Welding Current
The welding current must be regulated in accordance with the diameter of the
electrode and the thickness of the metal being used. Below is a table suggesting
suitable ratios.
Set up assembly
1. Put the wire on the hub feed clockwise. Hub is on hub feed spindle, Secure
the wire with the retainer washer.
2. Then place the tension spring on top of the retaining washer over the spindle.
Insert the keyed locking button into the end of the spindle and push down
turn the keyed locking button clockwise
3. Thread the wire through the feeding rod Loosen off the tension screw, feed the
wire until it comes into the intersection of the two rollers.
4. Apply pressure onto the arm between
the roller and the tension screw. Feed
the wire between the rollers manually
so it holds. Release pressure on arm
and tighten the tension screw.
5. Secure attach earth clamp out of the
way onto a non conductive surface.
(non metal e.g. a dry wooden bench )
6. Unscrew the shroud on the end of the mig torch and remove the welding tip.
Turn the machine onto wire speed feed only and the speed dial onto maximum.
Warning!
Make sure the earth clamp is not touching you and out of the way
and not touching an earth conductive surface
7. Turn the machine on pull the trigger on the torch gently and give short bursts
to feed the wire through the wire inlet. Once the wire is feed into the inlet
hold the trigger down until the wire is feed through the torch this can take
time. Allow around 20 secounds for this.
8. If the wire does not feed, increase the pressure on tension screw. Once the
wire is through the mig torch leave a few centimetres spare. Using pliers cut
excess wire to make it easier to attatch the welding tip.
