9 Weld Current Adjustment
Weld Current Adjustment Knob for Stick
MMA or TIG Mode.
10 Digital Display Volts
MIG Mode (GMAW): The display will
indicate Actual weld volts as measured at
output terminals. At the end of welding, the
display will hold the actual weld volts for 10
seconds. The display will indicate the MIG
Arc Control 0-10 setting by knob (11).
Stick Mode (MMA): The display will
indicate the amount of Arc Force 0-10 set
by Knob (11). During welding, the display
will show actual weld volts. At the end of
welding, the display will hold the actual weld
volts for 10 seconds.
Voltage Sensing (VS): The display will
indicate the weld volts setting set by Knob
(9). During welding, the display will show
actual weld volts. At the end of welding, the
display will hold the actual weld volts for
10 seconds.
TIG Mode (GTAW): During welding, the
display will show actual weld volts. At the
end of welding, the display will hold the
actual weld volts for 10 seconds.
11 Voltage Adjustment Knob
11.1 Stick Mode
When in Stick MMA Mode the knob will
adjust Arc force 0-10.
When the welding machine detects a
sudden drop in the weld arc voltage, the
machine will compensate momentarily
by increasing the weld current and
weld voltage.
A higher arc force might be useful for
difficult electrodes such as Cellulose.
11.2 Voltage Sensing
If Weld Mode is Voltage Sensing VS the
knob will adjust the weld volts setting
11.3 MIG Arc Control
When in MIG GMAW mode the harshness
of the arc can be adjusted. For example
aluminium welding would require a different
setting to steel welding. The display (10) will
indicate the MIG Arc Control value 0-10.
12 Process Selection Button
Pressing the button will cycle through each
of the four welding processes as indicated
by the four lights. The Four Processes are:
12.1 GMAW MIG using remote wire
feeder: The weld voltage is controlled
from the wire feeder and the set value is
displayed on (10). The output voltage is only
active when signaled from the wire feeder.
12.2 Stick electrode welding MMA, with
LOCAL control: Knob (9) will adjust the
weld current which is displayed on (8). Knob
(11) will adjust arc force displayed on (10).
12.3 TIG GTAW welding, LOCAL control:
Lift arc start, using TIG welding torch with
separate gas supply.
Knob (9) will adjust the weld current which is
displayed on (8).
12.4 MIG Process Voltage Sensing VS:
The Knob (11) will adjust the weld volts
setting, which is displayed on (10).
The output terminals are at full OCV.
This process requires a special wire feeder
that is capable of operating from output
live terminals.
Note: Process selection switch must
be pressed for 3 seconds, to lock into
VS Process.
13 Wire select Button and Indicator
Use this button to select the wire size
being used. For 350, sizes 0.9, 1.2, 1.6mm
can be used. For 500, sizes 0.9, 1.2, 1.6mm
can be used.
When wire setting is set to Gasless then
there is no need to select wire size.
