Narrower bead, with no visible cleaning
8. Pulse Frequency
Setting ranges 0.5HZ -200HZ
This parameter sets the PULSE FREQUENCY when the PULSE is ON.
7.Base Current
Setting ranges
10AMP to 200AMP (DC TIG mode), 10AMP to 200AMP (AC HF TIG mode)
Secondary current (TIG)/pulse pause current.

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
4T Latch mode this mode of welding is mainly used for long welding runs to reduce
operator fatigue. In this mode the operator can press and release the torch trigger and
the output will remain active. To deactivate the power source, the trigger switch must
again be pressed and released, thus eliminating the need for the operator to hold the
torch trigger.
11. Process Selection Button
(
AC/DC TIG 200P No plasma cutting function)
The process selection control is used to select the desired welding mode. Three
modes are available, MMA (Stick),GTAW (TIG) and CUT modes.
10. Trigger Mode Control Button (HF TIG and LIFT TIG Mode only)
The trigger mode control is used to switch the functionality of the torch trigger between
2T and 4T.

Press and hold the torch trigger to activate the power source (weld). Release the torch
trigger switch to cease welding.
2T Normal Mode In this mode, the torch trigger must remain pressed for thewelding
12. Pulse Button
Press the PULSE button to toggle Pulse On and OFF.
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.
13. Positive Welding Terminal
Positive Welding Terminal. Welding current flows from the Power Source via heavy
duty bayonet type terminals. It is essential, however, that the male plug is inserted
and turned securely to achieve a sound electrical connection.
