TIG Setup

!"#$%&8&

1. Connect the TIG Torch to the negative

welding terminal (-). Welding current

flows from the power source is

heavy duty bayonet type terminals. It is

essential, however, that the male plug is

inserted and turned securely

to achieve a sound electrical connection.

2. Connect the work lead to the positive

welding terminal (+). Welding current

flows from the Power Source is

heavy duty bayonet type terminals. It is

essential, however, that the male plug is

inserted and turned securely

to achieve a sound electrical connection.

3. Fit the welding grade shielding gas

regulator/flowmeter to the shielding gas

cylinder, then connect the shielding gas

hose from the regulator/flow meter outlet

gas INLET on the rear of the 186 AC/DC

Power Source. Connect the gas hose

from the TIG torch to the gas OUTLET

on the front of the

186 AC/DC Power Source.

Lift TIG and HF TIG Programming Modes

(Corresponding diagram on following page)

1.  Turn ON the ON/OFF switch located on the rear panel of the

power source.

2.  Press the PROCESS button to select LIFT TIG or HF TIG mode.

3.  Press the MODE switch to toggle between AC and DC welding

output.

4.  The Programming LED's are always active. Press FORWARD or

BACK to cycle through available programming functions.

5.  Use the Multi Function Control to adjust the parameter

selected.
