How to choose a cold welding machine

Cold welding demonstrates how welding can be done without the need for thermal energy. Scientifically it is possible to weld two pieces of metal together using the forces.

 Industries like aerospace, automotive, advanced fabrication applications, and laboratory experiments often use cold welding to join wires together.
There are different types of Cold welding machines in the market, below written free tips and tricks to choose the best welding machine according to your required task.

1: Welding efficiency

Generally, the productivity of a cold welding machine depends on the power output, more power output more quickly in welding speed. Presently in the market, a lot of the cold welding machine power output between 600-1000W, while an ATOM cold welding machine has 1200W, and its power output can reach 4000W making it quick in welding and super effective on energy saving.

2: Color difference

The color difference after welding is the final determiner of the welding effectiveness; the ATOM team will help you to choose the most suitable welding electrode to meet different castings, to reduce the color difference to the minimum.

3: The transformer

Common cold welding machines mostly use a traditional transformer, the voltage output unstable, easy to cut edge, and the surface of the workpiece after welding is mostly rough. ATOM cold welding machine uses a 3000w capacity inverter to replace the traditional transformer. Hence power output should be more stable.

4: Control mode

A Common cold welding machine uses an analog signal control, this type of control system has some problems like To use more internal potentiometer more easily do damage and cause a variety of faults and also not accurate control.  An ATOM cold welding machine uses a fully digital control, which is stable and easy to operate.

5: Anti-interference ability

A cold welding machine that is not equipped with an anti-interference circuit and radiation is stronger. An ATOM cold welding machine using anti-EMI and RFI circuits, small electromagnetic interference, and small radiation, can meet the international standard.

6: The welding gun

Common cold welding use old technology welding gun, high temperature when using, and the internal components are more easily to aging. A cold welding machine using a newly designed welding gun, smooth in welding, lower temperature, and long using life.

Suitable and stable cold welding equipment is very important, below some suggestions:


If you are an aspiring welder, it is important if you understand the different types of welding equipment to better your prospects for employment. If you can decide on which welding model would be more compatible for a particular project, you’d better your chances of being appointed as a supervisor or project assistant by an employer.
