1. Using the gas hose supplied connect the hose to the gas inlet
connection on the rear of the machine and tighten it with a
spanner.
2. Connect the opposite end of the gas hose to the output
connection of a gas regulator capable of supplying the correct
gas ow for the welding operation.
Note if the gas cylinder is to be stored on the back of the
machine ensure it is secured using the retention chain provided
6.0 Operation
1. Switch on the machine using the mains on/off switch, This lights
the Green LED above the voltage selector switch.
2. Select the welding mode using push button (13) and switching
option with Button (14)
6.1 MIG welding Feeding wire electrode
You can MIG weld in 2 modes Manual and Synergic the manual
mode takes more skill to setup.
Synergic MIG, (Carbon steels only)
Select the Synergic MIG mode using button (9)
Select the Gas type using button (13)
Select the wire diameter using button (12)
Rotate the amperage button (15) on the wire feeder to select the
desired welding amperage. The machine will adjust the welding
voltage automatically but you may trim the arc length using the
Voltage knob on the feeder to increase or decrease the arc length
which will be displayed on the V display. and the inductance to your
personal preference by adjustment of the Voltage knob (16) and
inductance (8) The voltage will increase or decrease penetration and
the inductance affects the arc stability and droplet transfer.
Manual MIG
Select the Manual MIG mode using button (9)
Select the desired welding voltage using the knob (16)
Select the desired welding amperage (wire speed) using the knob
(15). Note I manual mode the Amperage display shows wire speed
m/min when adjusting. You should then adjust the machine settings
until they are in balance with each other giving a smooth stable arc.
4T operation.
Operation in the 4T trigger mode gives the advantage of the
option of a crater ll current, at the end of the weld. Select 4T mode
using button (10). Using the control knobs on the front panel of the
machine in synergic mode you can select the nal current (6) and
trim the arc length with knob (7). If you are working in manual mode
then the parameter are arc voltage and wire speed.
You will note in this mode the main welding parameter are set on
the wire feeder and the crater ll parameters are set on the power
source and the display changes to display whatever is the currently
adjusted parameter.
In operation press and release the trigger to start and when you
reach the end of the weld, press and hold the trigger in which will
activate the crater ll settings until you release the trigger which
stops the welding process
Note: Check that drive rolls, and torch parts are correct for the
wire size and type being used.
3. The optimum idle roll pressure varies with type of wire, wire
diameter, surface conditions, lubrication, and hardness. As a
general rule, hard wires may require greater pressure, and soft,
or aluminium wire, may require less pressure than the factory
setting. The optimum idle roll setting can be determined as
follows:
4. Press end of gun against a solid object that is electrically
isolated from the welder output and press the gun trigger for
several seconds.
5. If the wire “bird nests”, jams or breaks at the drive roll, the idle
roll pressure is too great. Back the adjustment knob out 1/2
turn, run new wire. If the only result was drive roll slippage,
loosen the Hand nut on the central connector and pull the gun
forward about 6” (15cm) away from the power source. There
should be a slight waviness in the exposed wire. If there is not
waviness, the pressure is too low. Tighten the adjustment knob
1/4 turn, reinstall the gun cable and repeat the above steps.
1. When triggering, the electrode and drive mechanism are
electrically “LIVE” relative to work and ground and remain
“LIVE” several seconds after the gun trigger is released.
WARNING
When using an open arc process, it is necessary to use correct
eye, head, and body protection.
2. Position wire over joint. The end of the wire may be lightly
touching the work.
3. Lower welding helmet, operate gun trigger, and begin welding.
Hold the gun so the contact tip to work distance is about 3/8”
(10 mm).
4. To stop welding, release the gun trigger and then pull the gun
away from the work after the arc goes out.
5. When no more welding is to be done, close valve on gas
cylinder (if used), momentarily operate gun trigger to release
gas pressure and turn off the machine.
NOTE These settings are guidelines only. Material and wire
type, joint design, t up, position, shielding gas, etc. affect
settings. Produce test welds to be sure they comply to
specications.
Material thickness determines weld parameters.
1. Convert Material Thickness to Amperage (A) (0.25mm= 1 Amp)
3.2mm = 125 A
2. Select Wire Size
Amperage Range Wire Size
40 - 145 A 0.8 mm
50 - 180 A 1.0 mm
75 - 250 A 1.2 mm
3. Select Wire Speed (Amperage)
Wire Size Feed speed
0.8 mm 0.05m/min per Amp
1.0 mm 0.04m/min per Amp
1.2 mm 0.025m/min per Amp
