Transformer Corrugated Tank Fin Reinforcement Spot Welding Machine

This is one of our patented machines, designed in house for the best spot welding reinforcement on corrugated fin panels formed using a transformer corrugated tank fin production machine.

Two spot welding torches are driven by servo motors and PLC control. The height, position and stroke can be pre-set based on the fin panel height and width, and the welding process utilizes a resistance weld, quick welding speed, and a low noise level. Fin panel movement is driven by an inverter controlled motor, and the movement stroke can be preset based on the fin pitch.
