4.0 Description of Controls
Do Not operate this switch while welding
1.
Coarse Voltage selector switch. This switch is used to select
the require welding voltage each position of the switch
represents approximately 6V.
2.
On Off switch. The machine is switched off when the light (4)
is off and the fan is not running.
3.
Fine Voltage selector switch. This switch is used to select the
require welding voltage each position of the switch represents
approximately 0.5V.
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.
Do Not operate this switch while welding
6.
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
7.
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. Gas purge. Allows gas to flow through the
welding torch and so allow checking of the gas flow before
starting the welding process.
8.
Burn back control affects the wire feed motor over run when
the trigger is released and can be adjusted to ensure that the
wire does not burn back onto the contact tip at the end of the
weld. (Increase to reduce wire stickout).
9.
Soft start adjustment which controls the acceleration of the
wire feed motor when the arc starts to reduce spatter and give
a cleaner arc initiation.
