Helvi Spot Car 4000-TR Spot Welder

Power supply: 380 V, 3-phase AC input with a frequency range of 60–400 Hz. The welder supports high-current operation up to 4000 A for demanding spot welds.

It is capable of welding steel parts up to 6 mm thick.

Key features include a digital power setting display for precise amperage control, automatic welding current adjustment, a sprung-up arm design for greater stability, a profiled torch handle for a comfortable grip, a two-step cooling system for sustained performance, and a grounded setup for proper weld penetration.

The package includes a 10-meter air-cooled torch handle and cable, a range of electrodes and related accessories, and a comprehensive instruction manual for easy operation.

Set the welder on a stable surface, connect to a suitable 380 V 3-phase supply, establish a proper ground on the workpiece, use the digital display to set the desired current, and employ the sprung arm for stability during welding. Monitor the cooling system and follow the manual for step-by-step guidance and safety precautions.

Yes. The unit is described with a waterproof design and is intended for use in wet environments, provided you follow proper safety practices and ensure correct grounding and insulation.

Ideal for on-site repairs and fabrication tasks where you need fast, high-current spot welds. It’s well-suited for automotive sheet metal work, bracket assemblies, and frame components, especially in areas with limited access.

Compared with similar models on Fepy.com such as the Helvi Spot Car 2000-TR and Helvi Spot Car 3000-TR, the 4000-TR offers higher welding current for thicker or more demanding joints while maintaining rugged on-site usability.
