1. Digital Ammeter / Parameter meter
The digital Ammeter is used to display the actual output current of the power source. It is
also used to display Parameters in Programming Mode.
Depending on the Programming Parameter selected, the status indictor adjacent to the
Ammeter will illuminate to show the units of the programming parameter.
When welding, the Ammeter will display actual welding current.

the correct mains voltage is present.
3. Thermal Overload Indicator Light
This welding power source is protected by a self resetting thermostat. The indicator will
illuminate if the duty cycle of the power source has been exceeded. Should the thermal
overload indicator illuminate the output of the power source will be disabled. Once the
power source cools down this light will go OFF and the over temperature condition will
automatically reset. Note that the mains power switch should remain in the on position
such that the fan continues to operate thus allowing the unit to cool sufficiently. Do not
switch the unit off should a thermal overload condition be present.

Note: that when operating in GTAW (HF and LIFT TIG modes), the power source will
remain activated until the selected down slope time has elapsed
8. Process Selection Button
The process selection control is used to select the desired welding mode. Two modes
are available, GTAW (TIG), and MMA (Stick) modes.
9. Pulse Button
Press the PULSE button to toggle Pulse On and OFF.
10. Programming Parameter Indicators
These indicator lights will illuminate when programming.
Setting ranges
Arcforce:1-100AMP Hot Start:0.1-0.5S Hotstart current:1-100 AMP
Typically from 1 to 10 PPS. Provides a heating
and cooling effect on the weld puddle and can
reduce distortion by lowering the average
amperage. This heating and cooling effect also
produces a distinct ripple pattern in the weld
bead. The relationship between pulse frequency
and travel speed determines the distance
between the ripples. Slow pulsing can also be
coordinated with filler metal addition and
increase overall control of the weld puddle
In excess of 40 PPS, Pulsed TIG becomes more
audible than visible-causing increased puddle
agitation for a better as-welded microstructure.
Pulsing the weld current at high speeds-between
a high Peak and a low Background amperage-
can also constrict and focus the arc.This results
in maximum arc stability, increased penetration
and increased travel speeds(Common Range:
100-500 PPS).
The Arc-Sharpening effects of high speed
pulsing are expanded to new dimensions. The
ability to pulse at 5,000PPS further enhances
arc stability and concentration potential-which
is extre mely beneficial to automation where
maximum travel tspeeds are required.

2T Normal Mode In this mode, the torch trigger must remain pressed for thewelding
