4.2 Power Connection

The welder supports dual voltage input. Ensure the correct voltage is selected and the power source meets the requirements.

• Voltage Selection: The welder automatically detects 110V or 220V AC input.
• Circuit Breaker: For 110V operation, a dedicated 30 Amp circuit breaker is recommended to prevent tripping, especially at higher amperage settings. For 220V, consult local electrical codes for appropriate breaker size.
• Power Cord: Connect the power cord to a suitable electrical outlet.

4.3 Welding Cable Connection

Connect the electrode holder and ground clamp to the appropriate terminals.

• Electrode Holder: Connect the electrode holder cable to the positive (+) output terminal.
• Ground Clamp: Connect the ground clamp cable to the negative (-) output terminal.
• Cable Quality: The welder uses pure copper core cables for efficient power transmission with minimal loss. For enhanced performance or specific applications, consider upgrading the electrode clamp and ground clamp, potentially using DIN adapters for compatibility with professional-grade accessories.

5. Operating Instructions

5.1 Powering On and Current Adjustment

• Turn on the power switch located on the back of the unit.
• Use the current adjustment knob on the front panel to set the desired amperage. The digital display will show the current setting.
• Refer to welding rod manufacturer specifications for recommended amperage ranges for different rod types and material thicknesses.

5.2 Welding Technique

• Arc Starting: Initiate the arc by striking the electrode against the workpiece. The digital chip control facilitates immediate arcing.
• Maintaining Arc: Maintain a consistent and tight arc distance for stable and smooth welding. Inverter welders often require a tighter arc compared to traditional AC welders.
• Electrode Types: This welder is compatible with various electrode types, including 6013 and 7018 rods, which are commonly used for general-purpose and low-alloy steel welding, respectively.
• Material Thickness: The welder is suitable for welding metal up to approximately 3.0mm thickness effectively.

5.3 Overheating Protection

The welder features an automatic overheating protection system. If the machine operates continuously for approximately 10 minutes at high loads, the overheating protection may activate, temporarily stopping operation. The unit will automatically resume normal operation after a cooling period of about 2 minutes.

6. Maintenance

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

• Cleaning: Periodically clean the cooling fan and ventilation openings to prevent dust and debris buildup, which can hinder heat dissipation. Use compressed air for best results.
• Cable Inspection: Regularly inspect all welding cables, connections, and the power cord for cuts, fraying, or loose connections. Replace damaged components immediately.
• Storage: Store the welder in a clean, dry environment when not in use.
