4.5.1 CC (CONSTANT CURRENT) MODE
CC (Constant Current) Mode is commonly
referred to as - Stick Welding, Arc Welding,
or Shielded Metal Arc Welding (SMAW).
1. With the engine shut off, insert the twist
lock connections of the work clamp and
the electrode holder cables into the
welder connection ports on the control
panel. For Direct Current Electrode
Positive (DCEP), connect the electrode
holder to the positive (+) port, and the
work clamp to the negative (–) port.
2. Select the appropriate electrode for the
material and process being performed.
See
Table 4B: ELECTRODE
SPECIFICATIONS
for selecting an
electrode.
3. Place the ground clamp on the work
piece and insert the appropriate
welding rod into the electrode clamp.
4. Start the engine (
See Section 4.2,
Engine Start-up and Shutdown
Procedure
).
5. On the control panel, place the CC/CV
switch in CC mode. Place the DC
Charger/Welder switch in welder mode.
6. Adjust the power dial to the appropriate
amperage setting for the material and
the electrode being used. (See
Table
4B: ELECTRODE SPECIFICATIONS
for electrode amperage ratings). At
anytime during welding, the power dial
may be adjusted to the desired
amperage level.
7. When you strike the electrode against
the material being welded, the engine
will go to high idle and deliver the
selected amperage through the
electrode. Welding can now begin.
8. After a weld has been completed, and
there is no contact between the
electrode and the metal for 30
seconds, the engine will return to idle.
4.5.2 CV (CONSTANT VOLTAGE) MODE -
USING A VOLTAGE SENSING SUITCASE
FEEDER OR SPOOL GUN
CV (Constant Voltage) Mode – commonly
referred to as - Wire Welding, MIG welding,
or Gas Metal Arc Welding (GMAW)
1. With the engine shut off, insert the twist
lock connection of the ground clamp
into the negative (-) welder connection
port on the control panel. Insert the
power lead segment from the suitcase
feeder into the positive (+) welder
connection port on the control panel.
DANGER
DO NOT weld with the electrode holder
connected to the negative (-) port and the
work piece connected to the vehicle.
Bodily harm and equipment damage may
occur.
NOTE
The amps/volts display will read the set
value for five (5) seconds when the dial is
adjusted, and the actual output value five
(5) seconds after the dial has been
adjusted.
NOTE
If a longer welding lead is desired,
optional 25 and 50 ft. lead segments may
be purchased from Vanair
®
Manufacturing, Inc. for a maximum lead
length of 100 ft.
NOTE
When using a spool gun, an adapter with
contactor must be used. Please consult
the spool gun manufacturer for
appropriate adapter.
