TIG Setup

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.
