Stick / Smaw (Cc) Operation - ESAB 350mpi Instruction Manual

SECTION 3
G. Adjust the PANEL CURRENT potentiometer
to the desired welding current by depressing
the PRESET SWITCH and reading the value
in the AMPS DISPLAY.
In the remote position, the max output for MIG, TIG and
STICK is limited by the position of the "Panel" potenti-
ometer; i.e., for maximum output, the PANEL potenti-
ometer must be set to maximum.
When the HC-5 remote hand control (P/N 34838) is
plugged into the power source, the ARC FORCE poten-
tiometer (used for stick welding) on the power source is
disabled even when the power source's CONTROL
switch is placed in the PANEL position.
J. Make sure you have a good clean ground
and a secure workpiece. Also, ensure that
shielding gas is turned on and flowing.
K. To establish the welding arc;
1. TOUCH TIG - When selected, the volt-
meter will indicate a voltage of 4 to 5
volts. As the tungsten is touched to the
work piece the contactor will automati-
cally be energized and a limited short
circuit current of 25 amps will start to flow
in the welding circuit. Rock the torch
away from the workpiece and the weld-
ing arc will be established. The amper-
age will automatically increase to the
pre-set value.
2. TIG (scratch) Select PANEL or REMOTE
mode switch on the front panel.
3. Touch tungsten to work. Operate either
the foot or the hand operated torch switch.
Contactor will energize, and a limited
short circuit current of 28 amps will flow.
Back the torch away from the work piece
and the welding current will increase to
the value as controlled by the potentiom-
eter.
L. For remaining accessory operations, refer to
the appropriate instruction literature supplied
with your particular system.

NOTE

3.5 STICK / SMAW (CC) OPERATION

A. Make all secondary output connections to the
power source output receptacles as described
in section 2 and as shown in the appropriate
accessory instruction literature.
B. After the primary input connections have
been made in accordance with section 2,
close the main wall disconnect switch or
circuit breaker.
C. Place the primary power switch in the ON
position. This will apply power to the control
circuitry as indicated by the MAIN POWER
light on the front panel.
ELECTRIC SHOCK CAN KILL! When the PROCESS
SELECTOR SWITCH is set to the STICK position
the welding output will be energized and the elec-
trode in the holder will be "electrically-hot" and
could shock you.
D. Place the PANEL/REMOTE switch in the
desired position. Panel setting limits max
current in either mode. Use the PANEL posi-
tion for control from the power source's front
panel, or the REMOTE position for control
from a remote control accessory.
E. Place the PROCESS SELECT switch in the
STICK position. The welding output will be
energized and the electrode holder will be
"electrically-hot".
G. Set the ARC FORCE CONTROL to the mid
position.
I. Adjust the CURRENT for the stick electrode
type and diameter, as specified by the elec-
trode manufacturer, being used by depress-
ing the PRESET SWITCH and reading the
value in the AMPS DISPLAY. PRESET
SWITCH can only be used in the PANEL
position of the power source.
J. For remaining accessory operations, refer to
the appropriate instruction literature supplied
with your system.
