Welding Range: 0.5-10mm thin sheet
Stud Diameter: M3-M10
Welding Time: 1-3 milliseconds



Building on the inherent advantages of a capacitor‑discharge stud welder, this variant incorporates a robust automatic feed mechanism to boost overall throughput and eliminate interruptions caused by manual loading. The feed channel is highly integrated with the welding gun body, ensuring streamlined, centralized maintenance. Moreover, it can seamlessly interface with production lines, robotic cells, or conveyor systems to enable a flexible, fully automated manufacturing layout.

Non-contact welding, achieved by using a lift-type welding gun, is the most advanced welding method currently available for energy storage welders. This technique is especially suitable for welding thin sheets made from materials such as stainless steel and aluminum. The key feature of non-contact welding is that it ensures a strong, reliable weld without leaving any marks on the back of the workpiece, maintaining both aesthetic quality and structural integrity.

Capacitor energy storage stud welder: Thin plate welding through instantaneous discharge (1-3 milliseconds), suitable for 0.5-10mm thin plates, high welding quality, small heat impact, suitable for low carbon steel, stainless steel, aluminum alloy and other metals.
Drawn arc stud welder: Through continuous arc welding of thicker metals, suitable for medium and thick plates and large-scale structural welding, but the heat input is high and the welding process is long, which may affect the welding quality.
Capacitor energy storage stud welder is suitable for a variety of metal materials, including low carbon steel, stainless steel, aluminum alloy, brass, etc. It is more widely used when thin plate materials need to be precisely welded.
The main advantages of capacitor energy storage stud welding are fast welding speed, high precision, small heat impact, simple operation and strong adaptability. It can complete welding in a very short time without excessive heat input to the parent material, ensuring the welding quality.
