E. DIGITAL VOLTS DISPLAY - In the normal
mode, this large, easy to read digital display
indicates actual output voltage or preset voltage
level when the PRESET SWITCH is depressed.
If a machine error occurs this display will
automatically switch to the error mode and
display "Err".
F. FAULT INDICATOR - Indicates an improper
input line condition. The machine will not
energize. The machine must be reset by turning
the POWER “ON/OFF” SWITCH to "OFF" and
then back to “ON”, after the proper input voltage
is selected.
a. Indicator illuminated - A primary input over-
current condition has occurred.
b. Indicator blinking - The INPUT VOLTAGE
SELECT SWITCH at the rear of the
machine is set incorrectly for the primary
input voltage applied.
G. TEMP INDICATOR - Indicates that an over-
temperature condition has occurred and the
machine will cease to function. "Err 4" will
appear in the digital displays. The machine will
return to normal operation once the temperature
decreases to a safe operating level.
H. POWER INDICATOR - Indicates power is
present in the machine and that control circuits
are energized.
I. DIGITAL AMPS DISPLAY - In the normal mode,
this large, easy to read digital display indicates
actual output amperage or preset amperage
level when the PRESET SWITCH is depressed.
If a machine error occurs this display will
automatically switch to the error mode and
display the error code number.
J. OUTPUT CURRENT/VOLTAGE CONTROL -
Sets the welding power output of the machine.
When in the STICK, TIG, and Touch TIG modes,
this knob controls the output welding current
(amperes). When in the MIG mode, this knob
controls the welding voltage (volts).
K. PRESET SWITCH - When depressed, the digital
meters will display the adjustment level of the
OUTPUT CURRENT/VOLTAGE control. This
allows the welder the ability to quickly and easily
preset the desired output level before attempting
to weld. This greatly reduces the “trail & error”
approach to adjusting proper welding conditions.
1. PROCESS SELECT SWITCH in the MIG
mode - Depressing the PRESET SWITCH
displays the output voltage level in the
VOLTS window for the given OUTPUT
CONTROL setting.
2. PROCESS SELECT SWITCH in the STICK,
TIG, Touch TIG modes - - Depressing the
PRESET SWITCH displays the output current
level in the AMPS window for the given
OUTPUT CONTROL setting.
L. STICK ARC FORCE / MIG ARC TRIM - This
control allows the welder to fine tune arc
characteristics to suit specific applications and
individual preferences.
1. PROCESS SELECT SWITCH in the STICK
mode - the STICK ARC FORCE control
adjusts the amount of “digging” action when
the arc length is shortened. This adjustment
is based mostly on personal preference of the
welder.
a. Settings from 0 mid point toward
negative (-). The welding arc becomes
softer and has less penetrating power as
the welding arc length is shortened.
b. Settings from 0 mid point toward positive
(+). The welding arc becomes stiff and
has more penetrating power when the arc
length is held short.
2. PROCESS SELECT SWITCH in the MIG mode
- the MIG ARC TRIM control adjusts the arc
dynamic characteristics primarily for short arc
welding. This adjustment is based mostly on
personal preference of the welder.
a. Settings from 0 mid point toward
negative (-). The welding arc becomes
crisp with a higher buzzing sound. The
weld pool becomes less fluid and the
weld bead may become more crowned.
b. Settings from 0 mid point toward positive
(+).The welding arc becomes softer with
a more crackling sound. The weld pool
becomes more fluid and the weld bead
may be flatter.
M. PROCESS SELECT SWITCH - Selects the
desired welding process to be performed. Switch
selections and associated process are as follows:
Mig Position - Output is always energized
Contactor on - Gas Metal Arc Welding (GMAW)
- Short Circuiting Arc Welding
- Spray Arc Welding
- Flux Cored Arc Welding
Stick Position - Output is always energized
Contactor on - Shielded Metal Arc Welding (SMAW)
- Air Carbon Arc Gouging (ACAG)
Mig Position - Gas Metal Arc Welding (GMAW)
- Short Circuiting Arc Welding
- Spray Arc Welding
- Flux Cored Arc Welding
TIG Position - Gas Tungsten Arc Welding
(GTAW) scratch start
Touch TIG - Gas Tungsten Arc Welding
Position (GTAW) with Lift Arc
