Operation
14. 5 Pin Control Socket
The 5 pin receptacle is used to connect a trigger switch or remote control to the welding
Power Source circuitry:
To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.
1 . 5
Gas/electricity integrated interface
Connect Gas/electricityone-piece TIG torch gun and plasma torch.
16. Negative Welding Terminal
Negative 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.
17. Power switch
before using the machine. Pull the switch to the closure state of "AN" to operate the
machine, and pull the switch to "AUS" after use. Turn off the power input, and the machine
will stop operating.
18. Gas input port
The gas port is connected with the gas valve output port. After connection, check whether
there is gas leakage.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug
being fused in the terminal.
3.2 Setup for STICK (MMA) welding
For Alkaline Electrode,connect the electrode holder to the positive welding termimal

manufacturer. 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. Select STICK mode with the process selection

3.3 Set-up for HF TIG (GTAW) welding
Before any welding is to begin, be sure to wear all
appropriate and recommended safety equipment.
WARNING
NOTE
The following set up is known as Straight Polarity or DC electrode positive. This is commonly
used for DC HF TIG welding on most materials such as steel and stainless steel.
1. Switch the ON/OFF Switch (located on the rear panel) to OFF.
2. Connect the work lead cable to the positive output terminal, and the HF TIG Torch cable
to the negative output terminal.
3. Connect the gas line/hose to the proper shielding gas source.
4. Slowly open the Argon Cylinder Valve to the fully open position.
5. Connect the work lead clamp to your work piece.
6. The tungsten must be ground to a blunt point (similar to a pencil) in order to achieve optimum
welding results. See illustration. It is critical to grind the tungsten electrode in the direction the
grinding wheel is turning. Grind at a 30 degree angle and never to a sharp point.
7. Install the tungsten with approximately 1.6mm to 3.2mm sticking out from the gas cup,
ensuring you have correct sized collet.
