4.0 Description of controls
1. Gas purge button. Pressing this button allow gas to flow
through the welding torch and so allow checking of the gas flow
before starting the welding process.
2. Wire inching button, allows the welding wire to be fed through
the torch without engergising the welding power.
3. 2T 4T, when in the 2T position the torch trigger will have a
momentary operation ie the welding operation will start when
the rigger is depressed and stop when it is released. In the 4T
position a short press and release of the trigger will start the
welding operation and a short press and release with stop the
operation. The 4T mode is ideal for long welds as it reduces
operator fatigue.
4. Mains input light This light illuminates when the mains power is
connected and the machine is switched on.
5. Fault light This light will illuminate when a fault or over
temperature condition has occurred. If this light illuminates
allow the machine to cool with the fan still running until it
extinguished. If the light does not go off when the power source
has cooled down then have the machine checked by a qualified
engineer.
6. On Off switch. The machine is switched off when the light (4) is
off and the fan is not running.
7. Fine Voltage selector switch. This switch is used to select the
require welding voltage each position of the switch represents
approximately 0.5V.
Do not operate this switch while welding
8. Coarse Voltage selector switch. This switch is used to select the
require welding voltage each position of the switch represents
approximately 6V.
Do not operate this switch while welding
9. Wire feed speed adjustment, controls the speed of wire feeding
from 0.8 to 24 m/min. Increasing the wire feed speed also has
the effect of increasing the welding current
10. Digital display for amperage (displayed real time)
11. Digital display for amperage (displayed real time)
12. Torch connector The Euro connector provided the external
connection for the welding torch.
13. Work return lead connection. This socket allows connection of
the work return lead to the front of the machine.
14. Mains input connection Input connection for the pre-installed
mains cable.
15. Gas cylinder restraint chain Use to secure the gas cylinder
when mounted on the rear of the machine
16. Shielding gas input connection 3/8 BSP male connection for the
shielding gas input.
17. Soft start adjustment which controls the acceleration of the wire
feed motor when the arc starts to reduce spatter and give a
