5.2 Gas Connection (for TIG Welding)

For TIG welding, connect a shielding gas cylinder (typically Argon) to the gas inlet on the rear of the machine using the provided gas hose. Ensure all connections are secure and leak-free. Adjust the gas flow rate according to the welding parameters and material thickness.

5.3 Torch and Ground Clamp Connection

  • Connect the TIG torch to the appropriate connector on the front panel.
  • Connect the ground clamp cable to the negative (-) terminal. Attach the ground clamp securely to the workpiece, ensuring good electrical contact.
  • For MMA (Stick) welding, connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal.

6. Operating Instructions

The TIG-250MPC offers various welding modes. Select the appropriate mode and adjust parameters using the control panel and LED screen.

6.1 TIG Welding Mode

TIG welding provides stable and uniform solder joints, resulting in clean and aesthetically pleasing welds.

  • Select TIG mode on the control panel.
  • Adjust welding current (Amps) based on material type and thickness.
  • Ensure proper gas flow.
  • Initiate arc using Lift TIG or high-frequency start (if available).

6.2 Pulse TIG Welding Mode

Pulse TIG mode is ideal for welding thin materials or when heat input needs to be precisely controlled. It produces stable and uniform solder joints with reduced distortion.

  • Select Pulse TIG mode.
  • Adjust peak current, background current, pulse frequency, and pulse width as required.
  • Proceed with welding as in standard TIG mode.

6.3 MMA (Stick) Welding Mode

MMA mode is suitable for welding thicker materials and in outdoor conditions. The TIG-250MPC offers easy arc start and minimizes electrode sticking.

  • Connect the electrode holder and ground clamp as described in Section 5.3.
  • Select MMA mode.
  • Adjust welding current based on electrode type and diameter.
  • Strike the arc and maintain a consistent arc length.
