2. Safety Information

Always prioritize safety when operating welding and cutting equipment. Read and understand all safety warnings and instructions before use. Failure to follow these instructions may result in electric shock, fire, serious injury, or death.

Electrical Safety: Ensure proper grounding. Do not operate in wet conditions. Use appropriate personal protective equipment (PPE) including welding helmets, gloves, and protective clothing.
Fume Hazards: Welding and cutting produce fumes and gases. Work in a well-ventilated area or use fume extraction equipment.
Arc Rays: Arc rays can injure eyes and burn skin. Always use a welding helmet with the correct shade filter and wear protective clothing.
Fire and Explosion: Keep flammable materials away from the welding area. Welding sparks can cause fires. Have a fire extinguisher readily available.
Hot Parts: Welded materials and equipment parts can remain hot for a significant time after operation. Avoid contact with bare skin.
Machine Protection: The unit features advanced auto-protection against voltage fluctuation, overheating, and other abnormalities. If a fault occurs, the unit will shut down and display an error code. It will automatically restart once conditions stabilize.

Connect the gas hose from your shielding gas cylinder (e.g., Argon, CO2, or Argon/CO2 mix for MIG; Argon for TIG; compressed air for Plasma Cutting) to the appropriate gas inlet on the machine.
Attach the reducing valve to the gas cylinder and then connect the gas hose to the reducing valve.
Adjust the gas flow rate according to the welding process and material.

5.3 Wire Installation (for MIG/Flux Core)

The machine supports 2lb or 10lb spools of MIG wire with diameters of 0.023", 0.030", 0.035", 0.040", or 0.045".

Open the wire spool compartment.
Install the appropriate wire spool and thread the wire through the drive roller mechanism. Ensure the correct U-grooved drive roll is used for your wire type and size.
Close the compartment and ensure the wire is properly tensioned.

5.4 Torch and Ground Clamp Connection

Connect the desired torch (MIG, TIG, or Plasma Cutting) to its respective connector on the front panel.
Connect the ground clamp to the appropriate welding output terminal (Negative for most MIG/TIG, specific CUT Negative for plasma cutting).
