Operating & Safety Guide HW011
Feed the wire through the wire feed roller and into
the guide. Close the tensioning roller and set the
tension. Feed the wire through to the gun until
25mm of wire is exposed then re-fit the tip.
The welder offers a range of different settings to
suit the type of welding task being performed.
Work through the following list of options selecting the
settings best suited to the work.
Welding Mode Selector Switch…
This allows you to select one of four welding types.
2-times.
Squeeze the torch trigger to begin
welding, release to stop.
Spot.
Squeeze the torch trigger to begin
welding, then release. Welding will
stop automatically within the time
selected. See Welding Time.
4-times.
Squeeze the torch trigger then release
to begin welding, squeeze the trigger
then release a second time to stop.
Burn Back
(fitted inside the wire feed compartment)
.
Adjusts the time that the wire continues
to be fed after the welding current has
stopped. The time can be set between
0.05 seconds and 0.5 seconds.
Set the welding voltage and wire speed
appropriate to the total thickness of the metal
being welded.
Clamp the workpieces securely in their final
positions.
Ensure the metal to be welded is clean, dry and
free from rust, paint and grease. Aim to weld only
bright, bare metal.
Clip the earth clamp to
the work, as close to the
proposed weld as
possible to ensure good
electrical contact.
Open the gas regulator
to give a flow rate to suit
the wire speed.
Expose about 25mm of
wire before striking an
arc. Hold the welding
gun at an angle of 60-70
degrees to the surface,
squeeze the trigger to strike an arc.
If you have difficulty in striking an arc, snip off all
but about 25mm of exposed wire and try again.
BASIC TECHNIQUES
Continue holding the
trigger, keeping the arc
about 3mm long and
work slowly along the
line of the joint.
DO NOT allow the tip to
touch the work. At the
end of the weld simply
release the trigger.
Never push the equipment beyond its design
limits. If it will not do what you want with
reasonable ease and speed, assume you have the
wrong type or size of welder for the job. Ask at
your local HSS Hire Weld Depot for advice.
When not in use,
store the equipment somewhere
clean, dry and safe
from thieves.
Keep the equipment clean.
You will find this less of a
chore if you clean it up regularly rather than wait until
the end of the hire period.
Switch OFF and unplug the unit. Leave everything
to cool then take the earth clamp off the work.
Disconnect all leads and coil them up neatly ready
for return
, to your local HSS Hire Weld Depot.
