SINGLE MODE WELDING (CC)
1. Place the welding mode selector switch (Figure 29) in
the single mode position.
Figure 29. Single-Dual Selector Switch
(Single Position)
2. For CC welding, place the welding mode rocker switch
in the CC position (down).
Figure 30. Welding Mode Switch (CC Mode)
3. Place e-Mode selector switch (Figure 31) in the
desired position as defined by Table 19. This switch is
a 3-position rocker switch.

Note 1: If using two welders connected with different polartities to weld the same
work, the voltage between the holders may cause electric shock to the
operator.
Note 2: If using two welders connected with different polartities to weld the same
work, use separate grounds for each welder.
Note 3: NEVER switch the Single-Dual Selector Switch during welding operations.
Switch contacting failure may occur.
NOTICE
If the welding work requires a current of 240 amps or less
for single mode applications, place the e-mode selector
switch in the high/low or high position if bead appearance
or welding faults are a concern.
In addition, place the e-mode selector switch in the high
position if an AC load of 100 watts or an AC load with a
magnet switch is used.
4. If welding is started with the e-mode selector switch
in the variable/low position, the standard welding load
voltage is automatically calculated based on the preset
welding current (Figure 32) and the engine speed will
be controlled by the available kW capacity of the unit
for either single or dual mode operation.
The engine will then be placed into low-speed operation
about 9~10 seconds after a pause of welding work.
