Safety Information
Always prioritize safety when operating welding and cutting equipment. Failure to follow safety precautions can result in serious injury or death.
- Electric Shock: Welding and plasma cutting can cause fatal electric shock. Ensure proper grounding, wear dry gloves, and inspect cables for damage. Do not operate in wet conditions.
- Fumes and Gases: Welding and cutting produce fumes and gases that can be hazardous to health. Work in a well-ventilated area or use local exhaust ventilation.
- Arc Rays: Arc rays can burn eyes and skin. Always wear a welding helmet with appropriate shade, safety glasses, and protective clothing.
- Fire and Explosion: Sparks, hot slag, and hot metal can cause fires. Keep flammable materials away from the work area. Have a fire extinguisher readily available.
- Burns: Hot metal and equipment can cause severe burns. Wear protective gloves and clothing.
- Noise: Some operations may produce high noise levels. Wear hearing protection.
- Compressed Air/Gas: For plasma cutting and TIG welding, ensure gas cylinders are secured and connections are leak-free.

The TIG section illustrates the TIG torch connected to the negative terminal and the ground clamp to the positive, with a gas hose connection. The MMA section shows the electrode holder connected to the positive terminal and the ground clamp to the negative.
- Ground Clamp: Always connect the ground clamp securely to the workpiece or work table.
- Plasma Cutting (CUT):
- Connect the plasma torch to the designated connector (typically positive).
- Connect the ground clamp to the negative terminal.
- Connect an air compressor to the machine's air inlet. Ensure air pressure is within the recommended range (0.4-0.6 MPa).
- TIG Welding:
- Connect the TIG torch to the negative terminal.
- Connect the ground clamp to the positive terminal.
- Connect an inert gas cylinder (e.g., Argon) to the machine's gas inlet.
- Install the appropriate tungsten electrode (1.0/1.6/2.0/2.4/3.0mm) into the TIG torch. Sharpen the tungsten head for better welding results.
- MMA (STICK) Welding:
- Connect the electrode holder to the positive terminal.
- Connect the ground clamp to the negative terminal.
- Insert the appropriate welding electrode (2.5/3.2mm) into the holder.
Operating Instructions
After proper setup, you can begin operating the machine. Always wear appropriate Personal Protective Equipment (PPE).
General Operation Steps
- Turn on the machine's power switch.
- Press the "MODE" button to select the desired function (CUT, TIG, or MMA).
- Adjust the current using the main adjustment knob according to the material thickness and welding/cutting requirements.
- For TIG and CUT modes, ensure gas/air supply is open and set correctly.
- Begin welding or cutting, maintaining proper technique.
- After use, turn off the machine and disconnect power.
Plasma Cutting (CUT)
- Max Cutting Thickness: 1/2 inch (12mm).
- Current Range: 10-40 Amps.
- Materials: Stainless steel, alloy steel, mild steel, copper, aluminum.
- Procedure:
- Select CUT mode.
- Set desired cutting current and air pressure (0.4-0.6 MPa).
- Position the plasma torch nozzle close to the workpiece.
- Initiate the arc and move the torch steadily along the cut line.
- The "Arc Arc technology" allows cutting without the tip touching the metal, reducing slag and improving cut quality.
TIG Welding

The "Real welding" section on the left shows a weld bead with a distinct fish scale pattern, indicating the pulse function is enabled, resulting in a beautiful and smooth weld. The right section shows a weld bead that is disordered and uneven when the pulse function is turned off.
The pulse function improves welding aesthetics and quality, and extends tungsten life. Use the "PULSE" button to activate and adjust pulse parameters (peak current, base current, frequency, duty cycle).
