Capacitor Discharge Bolt Stud Welding Machine from China Suppliers - Efficient for Insulation Nails Production
Detailed Information
The stud welding machine is very time and cost saving, all stud welding constructions do not need drilling, punching, threading, riveting, threading and finishing steps. Welding torches continue to expand the application potential of structural design. In stud welding, the welding process is short in time, high in current and low in penetration.
Therefore, it can be welded to thinner sheets. Workpieces for stud welding must be welded from one side. Capable of welding in all positions, connected to restricted vertical bulkheads with the aid of extenders.
Main Features
- All welding machines use new electronic components.
- Adopt digital, soft switching inverter technology, small size, light weight, easy to move.
- The panel is simple and easy to adjust, and even new worker can weld it.
- Suitable for welding steel structures, building floor slabs, bridges, etc..
- Intuitive and clear digital display of welding current and welding time.
- Three-proof design for key parts, suitable for various harsh environments, stable and reliable operation.

Frequently Asked Questions
What are the main advantages of using a stud welding machine?
Stud welding machines save significant time and costs. The process eliminates traditional structural steps such as drilling, punching, threading, riveting, and post-welding surface finishing, greatly increasing design flexibility and production efficiency.
Can this stud welding equipment be used on thin metal sheets?
Yes, it is highly suitable for thin sheets. Because the stud welding process features a very short welding duration and low heat penetration combined with high current intensity, it prevents distortion and burn-through on thin workpieces.
What are the electrical installation requirements for the welder?
The machine requires an input voltage of AC three-phase 380V 50/60Hz, a power switch rated at 150A, an input cable size of ≥16mm², and an output cable size of 95mm² (with a welding gun cable length of ≦20m).
What environmental conditions are recommended for operation?
The recommended ambient temperature for operation is -10℃ to +40℃. Ensure that the air inlet and outlet vents remain unblocked, avoid direct sunlight exposure, and pay close attention to dust prevention for key internal components.
What standard and optional accessories are available?
Standard accessories include an Electrode Holder, Ground Clamp, Welding Mask, and a Brush/Hammer. Optional upgrades include a professional auto-darkening Welding Helmet, Welding Gloves, E6013 Electrodes, and a Lift TIG Torch.
