Operation in the owner’s manual that came with your 180AP.
180AP TIG Setup
•Gas Purge – Pressing this button turns on the gas solenoid. Pressing the Gas Purge button again
shuts off the gas solenoid.
•HF Start - For HF non-contact arc starting Press the HF Start button. The yellow light illuminates.
oFor Lift TIG contact arc starting HF light is OFF.
•Pulse – To select Pulse TIG mode Press the Pulse button. Yellow light will illuminate.
oPulse parameters are Iw, Ib, Dcy, Fp.
Iw – Peak current
Ib – Background Current
Dcy – Ratio of time spent at peak pulse. If set at 50%, then 50% of each cycle
will be at peak current.
Fp – Pulse Frequency in Cycles Per Second.

•2T/4T Remote Control – Select 2T (2 arrows one up one down) when using a foot control. Select
4T (2 Double arrows) when using the controls on the supplied TIG torch.
•AC/DC Selection – Selects AC or DC output.
•STICK Functions - Arc Force, Hot Start. Select by pushing the STICK button.
•Parameter select & Set – Used to select Parameter and set value. Rotate knob to select
parameter. Push knob and then rotate to set parameter value.

Parameter setup
Start left to right. Rotate the red knob to highlight the Parameter to adjust. The yellow light will
illuminate to show selection. Push red knob to set parameter value.
1. Tpr - Gas Pre-Flow. Value in seconds.
2. Is – Starting Current. Value in Amperage. Used in 4T mode.
3. Tup – Up Slope Time. Value in seconds. Set to zero when using a foot control.
4. Iw – Welding amperage. Value in Amps.
a. Also Peak Pulse when in Pulse Mode.
5. Dcy – Pulse Width. Only available when in Pulse Mode.
6. Fp – Pulse Frequency. Only available when in Pulse Mode.
7. Ib – Background amperage. Only available when in Pulse Mode.
8. Tdown – Down Slope Time. Value in seconds. Set to zero when using a foot control.
9. Ic – Crater current – Value in Amperage. Used in 4T mode.
10. Tpo – Pulse flow – Value in seconds.
11. AC frequency – AC welding frequency. Value in Hertz.
12. Balance – AC welding. Cleaning control. Increasing the percent increases cleaning.
Using supplied TIG Torch
•Supplied TIG Torch has three buttons on the handle.
oBigger Button at the top is ON/OFF.
oThe two smaller are amperage control UP and Down.
oSet the 2T/4T Remote Control Button on the front panel
for 4T operation.
4T setting.
o4T operation in HF Start mode.
Press and hold close the ON/OFF button. Pre
flow starts, then HF starts to transfer arc at
Starting Current amperage setting.

Release ON/OFF button. Amperage increases at set up slope time to weld
current. Now use the two smaller buttons to increase or decrease amperage
while welding.
Press and hold close the ON/OFF button again. Amperage decreases at set
Down Slope time to crater amperage.
Release ON/OFF button. Arc stops then post flow.
•TIG operation with Foot Control
oSet the 2T/4T Remote Control Button on the Front Panel for 2T operation.
2T Setting.
Set up slope and Down Slope settings to zero.
