　　Product Advantages:

1. Microprocessor Control – Welding time controlled by an internal microprocessor for enhanced reliability and operational ease

2. Dual-welding function – capable of connecting two manual welding torches, or one automatic welding torch and one manual welding torch, or two automatic welding torches

3. Current Shift Function (Optional) – Three adjustable current levels, suitable for different sizes of weld nails, and less prone to damage

4. Independent Welding Parameters – The welding parameters for the two welding torches are set independently, without affecting each other.

5. System Monitoring – Continuously in monitoring mode during equipment operation

6. Display Error Code – Error codes are displayed on the digital tube when the device malfunctions.

7. Lift Test – The welding gun and nozzle can test the lift function without welding the bolt.

　　Structural Features:

1. Very easy to operate

2. The body structure is compact and has a small size.

3. Durable and Robust – Metal housing, suitable for harsh working environments

4. Electromagnetic Shielding – Prevents electromagnetic fields from interfering with the control unit, ensuring stable operation of the equipment.

5. Air-Cooled Channel – Independent cooling channel that enhances transformer heat dissipation and reduces dust interference on the control unit.

　　Safety:

1. Integrated Power Filter (to prevent voltage peak fluctuations from affecting)

2. Suitable for use in work sites with significant voltage fluctuations

3. Passed EMC Testing (Electromagnetic Compatibility Testing)

4. High-voltage testing

5. Repeat Weld Trigger Lock – Prevents re-welding on already welded rivets

6. Transformer Temperature Monitoring – The machine will automatically shut down and cool down when the transformer temperature is too high.

7. Temperature-Controlled Cooling Fan - Significantly reduces equipment operation noise and dust impact

8. Strong resistance to external interference

9. Protection Class: IP23

10. Outdoor operation permitted
