8. PREPARING THE WELDERS
i. Lift the latch to release the side cover
.
ii. For smaller reels; remove the locking
nut and spring . Install the
small spool onto the spool holder.
Refit in reverse order.
iii. Fit the wire spool so that it feeds off the top
of the roll towards the wire drive unit.
iv. Loosen tensioner (see page 13)
anticlockwise enough to swing it downwards
and raise arm , moving the tension
roller .
v. Trim 10cm of wire and discard it,
before flattening out the next 15cm.
Do not let the wire lose tension.
vi. Pass the filler wire through the guide
and underneath the tension roller .
The drive roller comes with two grooves for
different wire gauges. Remove nut to see
the groove size that is NOT in use.
Note: The wire must sit in the appropriate groove
for the wire gauge. The groove size is etched on the
side of the roller. To reverse the roller, remove nut
and flip the drive roller over before refitting nut.
vii. Make sure the wire is well inside the torch
liner before closing the arm and
tensioner .
viii. Connect the welding machine to the power
supply. Position the switch to ‘on’. This will
be 230V or 400V depending on the power
supply you connect the machine to.
ix. Unscrew/remove the gas shroud and
with a small spanner unscrew and remove
the tip . Pull the trigger and
observe the wire feed mechanism. If the wire
is being fed correctly it will come out of the
swan neck. Pass the tip over the wire and
secure back onto the swan neck. Do not
over tighten. Re-secure the gas shroud and
trim the wire back as required.
Caution:
Do not look directly into swan neck as if filler
wire emerges suddenly, serious injury could occur.
Note:
Ensure the tip size matches the wire size prior
to installing.
