4.2 Wirefeeder Controls
Fig 2
Controls on front face of wirefeeder
1 Power On Indicator
This indicator is illuminated when wirefeeder
is connected to a power source and the
power source is switched on.
2 Fine Voltage Control
The Fine Voltage Control provides variable fine
adjustment of the output welding voltage.
3 Arc Start
This control can be set to modify arc starting
conditions. For many applications the control
can be set at the mid point.
Rotating the knob towards ‘FAST’ will
provide faster wire acceleration at arc start
giving quicker starts, suitable for applications
such as rapid tack welding.
Rotating the knob towards ‘SOFT’ will slow
wire acceleration, providing a softer start
suitable for larger diameter and aluminium
wires.
4 Wire Speed Control
This control sets the speed of the wire drive
motor within the range of 0 - 172 RPM,
equivalent to 0 - 20 metres per minute of
welding electrode wire. Rotate the control
clockwise to increase the feed speed. This
control is used in conjunction with the Wire
Speed Range Select Switch. Switch to low for
slower wirespeed control and switch to high
for higher wire speeds.
5 Wire Speed Range Indicator Light
This indicator is illuminated when speed
range is set to High speed range (8-20
metres/min).
6 Wire Speed Range Select Switch
Press to change from Low wire speed range
to High wire speed range.
