Operating & Safety Guide HW009
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 and welding will stop
automatically within the time selected.
See Welding Time.
Stitch.
In this mode, when the torch trigger is
squeezed the unit automatically welds –
pauses – welds again – pauses again and
so on. The welding current duration is
controlled by the welding time dial and
the pause time is adjusted by the pause
time control.
4-times. Squeeze the torch trigger then release to
begin welding, squeeze the trigger then
release a second time to stop.
Burn Back…
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.
Wire Feed Speed Dial…
Adjusts the speed at which the wire is fed to the
work, variable between 0.5 metres and 14 metres
per minute.
Welding Voltage Selector…
This is used to set the welding current.
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.
BASIC TECHNIQUES
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.
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.
