4. Setup

1. Unpacking: Carefully remove the welder and all accessories from the packaging. Inspect for any shipping damage.
2. Power Connection: Connect the power cord to a suitable 230V AC power outlet. Ensure the outlet is properly grounded and can supply the required current (10-160A).
3. Ground Clamp Connection: Connect the ground clamp cable to the negative (-) output terminal of the welder. Securely attach the ground clamp to the workpiece or welding table, ensuring good electrical contact.
4. Electrode Holder Connection: Connect the electrode holder cable to the positive (+) output terminal of the welder.
5. Electrode Insertion: Insert the desired electrode (1.6-4.0mm diameter) into the electrode holder.
6. Ventilation: Ensure the welding area is well-ventilated to disperse fumes.

5. Operating Instructions

1. Power On: Turn on the power switch located at the rear of the unit. The digital display will illuminate.
2. Current Adjustment: Use the current adjustment knob on the control panel to set the desired welding current (Amperes). Refer to the electrode manufacturer's recommendations for appropriate current settings.
3. Safety Gear: Put on all necessary personal protective equipment (PPE), including a welding helmet, gloves, and protective clothing.
4. Start Welding: Bring the electrode into contact with the workpiece to strike an arc. Maintain a consistent arc length and travel speed for optimal weld quality.
5. Monitor Performance: Observe the digital display for current readings and any error indicators. The machine features IGBT technology for stable arc performance.
6. Cooling: The internal fan will operate during use to cool the components. Avoid blocking the ventilation openings.
7. Power Off: After welding, turn off the power switch and allow the machine to cool down before storing.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welder.

• Cleaning: Periodically clean the exterior of the machine with a dry, soft cloth. Use compressed air to blow out dust from the ventilation openings, ensuring the machine is unplugged first.
• Cable Inspection: Regularly inspect welding cables, electrode holder, and ground clamp for damage, fraying, or loose connections. Replace damaged components immediately.
• Terminal Check: Ensure all electrical connections at the output terminals are tight and free from corrosion.
• Storage: Store the welder in a dry, clean, and well-ventilated area, away from direct sunlight and extreme temperatures.
