Stud Welding Machine


What is Cold Welding Machine Advantages?

High Welding Strength

The cold welding machine has a full metallurgical fuse, the repairing places can be subject to milling and filing and other post-process.


High Repairing Precision

Round wires can be used to repair. It’s without losing the original base level, less redundant solders, and easy for post-phase shaping. The minimum repair amount is 0.05mm (filling material of 0.05m in diameter is used).

Fast Repairing Speed

Fastest repairing amount is up to 100 /min.

Less Damage to Base Materials

Cold welding machine has small hot spots, without causing annealing and deformation of the base material.

Reasonable Distribution of Power

It adopts microcomputer chip control and various materials of different diameters can obtain the best power.

Large Adaptive Range of Voltage

Switching power supply is used. When the voltage changes fluctuate within the range of ±20%, this machine can work in normal state and maintain a stable output power.

Convenient for Electricity Connection

With a quick connector, it is very convenient for connection and installation.

Easy to Carry

Small size of the whole machine (375×150×230), lightweight:9kg.
