• 1 x Portable strap

3. Setup

Before operating the welding machine, ensure it is properly set up.

1. Unpacking: Carefully remove the welding machine and all accessories from the packaging. Inspect for any damage.
2. Placement: Place the welding machine on a stable, level surface in a well-ventilated area, away from moisture and flammable materials. Ensure there is sufficient space around the machine for air circulation.
3. Connect Earth Clamp: Connect the earth clamp cable to the negative (-) terminal on the front panel of the welding machine. Secure the earth clamp to the workpiece or a sturdy metal table that is electrically connected to the workpiece. Ensure a good electrical connection.
4. Connect Electrode Holder: Connect the electrode holder cable to the positive (+) terminal on the front panel of the welding machine.
5. Power Connection: Ensure the welding machine's power switch is in the OFF position. Connect the power plug to a suitable 1~220-240V, 50/60Hz grounded power outlet.
6. Install Portable Strap: Attach the portable strap to the designated points on the welding machine for easier transport.

4. Operating Instructions

Follow these steps for safe and effective welding:

1. Power On: Turn the power switch to the ON position. The LED display will illuminate.
2. Select Electrode: Choose an electrode suitable for your material and welding task. The machine supports electrodes from 1.6mm to 3.2mm.
3. Adjust Current: Use the current adjustment knob to set the desired welding current (15A-130A). The digital display will show the selected amperage. Refer to electrode manufacturer guidelines for recommended current settings.
4. Insert Electrode: Securely insert the electrode into the electrode holder.
5. Prepare for Welding: Put on all necessary PPE, including the welding helmet. Ensure your work area is clear and safe.
6. Strike an Arc: Gently tap or scratch the electrode against the workpiece to strike an arc. Once the arc is established, maintain a consistent arc length and travel speed. The Hot Start feature assists in easier arc ignition, and Arc Force helps prevent the electrode from sticking.
7. Welding: Guide the electrode along the joint, maintaining a steady hand and proper angle. The Anti-stick feature will reduce the current if the electrode sticks, making it easier to detach.
8. Finish Welding: When finished, lift the electrode from the workpiece to break the arc. Turn off the welding machine. Allow the workpiece to cool before handling.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your welding machine.

• Cleaning: Periodically clean the machine's exterior with a dry cloth. Use compressed air to blow out dust from the ventilation openings. Ensure the machine is disconnected from power before cleaning.
• Cable Inspection: Regularly inspect all cables (power, electrode holder, earth clamp) for cuts, fraying, or damaged insulation. Replace damaged cables immediately.
• Terminal Check: Ensure all electrical connections and terminals are clean and tight.
• Storage: Store the welding machine in a dry, clean, and dust-free environment when not in use.
• Professional Service: For internal repairs or complex issues, contact qualified service personnel. Do not attempt to open the machine casing yourself.
