DA902 Transformer Arc Welding Screw, German technology, Made in China. The product is developed by Shanghai Yueshi Welding Technology Co., Ltd.

Welding Method:

Short-cycle unprotected arc welding, short/long-cycle gas shielded arc welding, long-cycle porcelain ring shielded arc welding

Applicable Occasions:

Suited for cold/hot rolled steel sheets, copper-coated steel sheets, and stainless steel sheets, ideal for use in the automotive and locomotive manufacturing industry, elevator manufacturing, ship and hull manufacturing, air cushion cabinet manufacturing, non-stick aluminum cookware manufacturing, and structural engineering sectors.

Product Advantages:

1. Microprocessor Control - Welding time controlled by an internal microprocessor, enhancing both weldability and operational convenience. 2. Two-to-One Function - Compatible with two manual welding torches, one automatic and one manual torch, or two automatic torches. 3. Current Gear Function (Optional) - Three adjustable current settings, suitable for various sizes of weld pins, and less prone to damage. 4. Independent Welding Parameters - Welding parameters for two torches can be set independently without affecting each other. 5. System Monitoring - The system is constantly in a monitoring state during equipment operation. 6. Display Error Codes - When a fault occurs, the device displays an error code on a digital display. 7. Lift Testing - The welding torch and tip can test the lift function without welding bolts.

Structural Features:

1. Very easy to operate 2. Compact body structure, small in size 3. Durable – metal casing, suitable for harsh working environments 4. Electromagnetic shielding – prevents electromagnetic fields from interfering with the control unit, ensuring stable equipment operation 5. Air-cooled channel – vertical cooling channels, enhancing transformer heat dissipation, reducing dust interference to the control unit

Gender:

1. Integrated power filter (to prevent voltage peak fluctuations) 2. Suitable for use in work sites with significant voltage fluctuations 3. Passed EMC testing (Electromagnetic Compatibility testing) 4. Passed high-voltage testing 5. Repeated welding trigger lock – Prevents re-welding on already welded pins 6. Transformer temperature monitoring – Automatically shuts down and cools down when transformer temperature is too high 7. Temperature-controlled cooling fan – Significantly reduces equipment working noise and dust impact 8. Strong resistance to external interference 9. Protection rating: IP 23 10. Suitable for outdoor operation
