Hand Held Spot Welding Machine

A hand held spot welding machine is a portable resistance welding device that breaks free from the constraints of traditional fixed welders. With the welding gun connected to the power source via a flexible cable, the operator can reach deep into workpieces or access hard-to-reach areas. Whether for automotive sheet metal repair, stainless steel door manufacturing, battery pack assembly, or hardware production, the handheld spot welder delivers flexible operation and stable weld quality - a versatile tool for workshops and job sites alike.

Flexible & Portable - No Site Restrictions
Compact and lightweight, the machine features wheels for easy mobility. The welding gun connects via an extended water-cooled cable (standard 2m, custom lengths available), allowing the operator to reach the workpiece directly - ideal for welding large cabinets, enclosures, stainless steel doors, and other immovable workpieces.

Resistance Spot Welding Principle - Reliable Joints
Utilizing resistance spot welding technology, the machine applies pressure and high momentary current through electrodes, generating resistance heat at the contact surface to form a weld nugget. Strong welds with minimal deformation, suitable for spot and projection welding of various metals.

SCR Non-Contact Switching - Precise Control
The main circuit features diode SCR non-contact switching for fast, accurate, and reliable operation. Welding time is precisely adjustable via the control system, ensuring excellent repeatability and consistent weld quality.

Multiple Models - Covering Various Thicknesses
Available in DN3 series models from 16KVA to 50KVA, covering welding thickness from 0.1mm to 3.8mm for mild steel. Lightweight portable models also available for different applications.

Water-Cooled Welding Cable - Sustained Operation
Secondary welding cables feature water cooling to effectively manage temperature rise during extended operation - ensuring stable performance and extending cable and electrode life.

No Air Source Required - Plug and Play
Unlike pneumatic spot welders, handheld models require no external compressed air - simply connect to power and start working, reducing setup costs and requirements.
