Welding Wire Settings Selection
There are many variables that you will need to take into account
when choosing your welding wire size and type. Below are some
of the factors that should be considered:
• Type & thickness of the material to be welded
• Position and type of welding joint
• Maximum welding capacity of your welder
• How much penetration will be required for strength
• Type of bead desired for the weld
• Whether you are using a shielding gas or not

Note:
The above chart is only intended as a general guide. Proper
welding will also depend on how close the torch is held to the
material and the speed it is moved along the weld. Always test
new settings on a scrap piece of material first. Proper welding
takes good technique and practice.
Aluminium Welding
For aluminium welding, aluminium wire must be used. The
workpiece must be thorougly cleaned with a stainless steel wire
brush to remove oxides and impurities from the weld surface.
Depending on the thickness of the workpiece, it also may require
additional heat sinks to be attached to the workpiece. Ensure
proper tip-to-work distance to prevent wire burning back to the
contact tip.
4. CONTROLS
OPERATION
ON/Off Switch
The on/off switch is located on the rear of the welder.
1. Press the on/off switch into
the on position ‘I’ to switch
the unit on.
2. To switch the unit off, press the switch to the ‘0’ position.
Note:
Check the rating of the circuit breaker on the supply
and other appliances connected to the circuit. The welder is a
high powered device and it is recommended that it is the only
appliance on the circuit to ensure it has enough power to operate.
Note:
If a 15A circuit is available, it is recommended that the
welder be connected to this.
WARNING!
DO NOT LEAVE THE SWITCH IN THE
ON POSITION WHEN THE UNIT IS NOT IN USE AS
THIS POSES THE RISK OF ELECTROCUTION OR
ACCIDENTS HAPPENING FOR THE NEXT USER.
Wire Feed Speed
The wire feed speed should be
adjusted to suit the application
and material being welded.
Refer to the Welding Wire
Settings Selection Table as a
guide.
Note: Always test settings on a
scrap piece of material first.
Variable Voltage
The voltage should be set
according to the application,
material being welded and wire
feed speed.
1. The voltage can be
increased or decreased by
turning the voltage control
dial.
