OPERATING INSTRUCTIONS….cont
PREPARATION FOR WELDING
Fit the correct size tip to match your wire & wire feed roller.
Set the voltage and wire speed by turning the appropriate controls.
Switch the welder on.
Press the torch trigger and feed the wire out slightly.
Cut the wire about 3mm from the end of the mig tip.
Turn on the gas supply (T136 & T166 only).
Note:
If using solid wire check the gas is the correct type and the gas regu-
lator (not supplied) is turned on.
WELDING
Switch the welder on.
Hold the torch out straight and press the torch trigger until the wire passes out of
the end of the torch.
Refit the MIG tip and shroud.
Adjust the pressure adjustment knob so the wire feeds smoothly but not so
much that the wire is crushed.
Note:
If the arc has a humming sound and a blob forms on the end of the mig tip then you
have insufficient wire speed and it should be increased. If the arc has an erratic sound, and
the torch feels that the wire is hitting against the work then the wire speed is to high. When the
wire speed is correct you should get a steady crackling sound.
Position the torch so the mig tip is about 6mm from the point where the welding
is to commence.
Press the torch trigger and the wire will feed, move the torch slowly in the cho-
sen direction.
Once the weld is completed, release the torch trigger.
For future reference make a note the voltage and wire speed setting material
that has been welded.
Clean the area to be welded, and the earthing point of all rust, paint and con-
taminants etc.
Place the earth clamp on to a cleaned area of the work piece.
Connect the welder to the electrical supply but do not switch on.
Note:
It is advisable to check the correct settings on a scrap piece of met-
al which is the same as the one to be welded.
