2. Safety Instructions
Welding can be dangerous if proper safety precautions are not observed. Always prioritize your safety and the safety of others. Failure to follow these instructions may result in serious injury or property damage.
2.1 Personal Protective Equipment (PPE)
- Welding Helmet: Always wear a welding helmet with appropriate shade filter to protect your eyes and face from arc rays and sparks.
- Protective Clothing: Wear flame-resistant clothing, long sleeves, and trousers to protect skin from burns and UV radiation.
- Gloves: Use heavy, flame-resistant welding gloves to protect hands.
- Footwear: Wear sturdy, closed-toe shoes, preferably leather, to protect feet from falling objects and sparks.
2.2 Work Area Safety
- Ventilation: Ensure adequate ventilation to remove welding fumes and gases. Work in an open area or use fume extractors.
- Fire Hazards: Keep the work area free of flammable materials. Have a fire extinguisher readily available.
- Electrical Safety: Ensure the welding machine is properly grounded. Do not operate in wet conditions. Inspect cables for damage before each use.
- Clearance: Maintain a safe distance from bystanders and ensure they are protected from arc flash and sparks.
2.3 General Precautions
- Do not touch live electrical parts.
- Disconnect power before performing any maintenance or adjustments.
- Never weld on containers that have held flammable materials.
- Avoid inhaling welding fumes.

5. Setup
Before starting any welding operation, ensure the welder is placed on a stable, non-flammable surface in a well-ventilated area.
- Connect Ground Clamp: Attach the ground cable to the negative (-) terminal on the front panel of the welder. Secure the ground clamp firmly to the workpiece or a clean, bare metal part of the welding table, ensuring good electrical contact.
- Connect Electrode Holder: Attach the welding cable with the electrode holder to the positive (+) terminal on the front panel. Insert the appropriate electrode into the electrode holder.
- Power Connection: Ensure the welder's power switch (located at the rear) is in the OFF position. Connect the power plug to a standard 230V AC power outlet.
- Select Electrode: Choose an electrode suitable for your material and welding task. The welder supports electrodes from 1.6 mm to 3.2 mm in diameter.

6. Operating Instructions
Once the setup is complete and all safety precautions are in place, you can begin welding.
- Power On: Flip the power switch at the rear of the welder to the ON position. The digital display will illuminate.
- Adjust Welding Current: Use the rotary knob on the control panel to set the desired welding current (20-120 A). The optimal current depends on the electrode diameter and material thickness.
- Initiate Arc: Strike the electrode against the workpiece to initiate the arc. The integrated Hot-Start function provides an initial surge of current to facilitate easier arc ignition.
- Maintain Arc: Hold the electrode at a consistent angle and distance from the workpiece. The Arc-Force function helps stabilize the arc, preventing it from extinguishing during welding.
- Prevent Sticking: If the electrode sticks to the workpiece, the Anti-Stick function will automatically reduce the current, allowing you to easily detach the electrode without damaging the machine or the electrode.
- Welding Process: Move the electrode steadily along the joint, maintaining a consistent arc length.
- Power Off: After welding, turn the power switch to the OFF position. Allow the machine to cool down.
- Clean Weld: Use the chipping hammer to remove slag from the weld bead, then clean with the wire brush.
Note: Practice on scrap material before attempting critical welds. Always wear appropriate PPE.
7. Maintenance
Regular maintenance ensures the longevity and reliable performance of your welding machine.
- Cleaning: Periodically clean the exterior of the welder with a dry, soft cloth. Use compressed air to blow out dust and debris from the cooling vents, ensuring they are not obstructed.
- Cable Inspection: Regularly inspect all welding cables, the electrode holder, and the ground clamp for signs of wear, cuts, or damage. Replace damaged components immediately.
- Terminal Connections: Ensure all cable connections are tight and free from corrosion.
- Storage: Store the welder in a clean, dry place, away from moisture and extreme temperatures.
- Duty Cycle: Observe the duty cycle (35% at maximum current) to prevent overheating. Allow the machine to cool down during prolonged use.
8. Troubleshooting
This section addresses common issues you might encounter during operation.
| Problem | Possible Cause | Solution |
|---|---|---|
| Welder does not power on. | No power supply; Power switch off; Faulty power cable. | Check power outlet; Ensure power switch is ON; Inspect and replace power cable if damaged. |
| Arc is difficult to strike or unstable. | Incorrect current setting; Poor ground connection; Damp electrode; Incorrect electrode type. | Adjust welding current; Ensure ground clamp has good contact; Use dry electrodes; Select appropriate electrode. |
| Electrode sticks frequently. | Low current setting; Incorrect arc length; Damp electrode. | Increase welding current; Maintain proper arc length; Use dry electrodes. The Anti-Stick function should help. |
| Welder overheats and shuts down. | Exceeded duty cycle; Obstructed cooling vents; High ambient temperature. | Allow welder to cool down; Clear cooling vents; Work in a cooler environment. |
If the problem persists after attempting these solutions, please contact customer support.
