The difference between cold welding machine and tungsten argon arc welding machine repair is as follows:

1 Difference in welding temperature: the welding pool temperature is one-third lower than that of tungsten argon arc welding machine two. The welding time of the cold welding machine is precisely controlled, and the temperature of the base metal after high-current welding is only a few dozen degrees, which can be touched by hand.

2. The difference in deformation amount: thin plates are not easily deformed during welding. The welding temperature is much lower than that of the argon arc welding machine. The cold welding machine has great advantages over the argon arc welding machine in thin plate welding. The welding deformation of the thin plate is very small. The thinnest manual welding can achieve high-quality welding of 0.2mm plates. Compared with tungsten arc welding machines, cold welding machines are less likely to burn through.

3 The difference in the brightness of the solder joint bead: The solder joint bead of the cold welding machine is white and bright, and will not turn yellow or black after welding like the tungsten electrode argon arc welding machine. It eliminates the cumbersome procedures of grinding, polishing and waxing the weld seam after welding.

4 Differences in welding machine functions: Cold welding machines have a variety of welding modes, including: precision spot welding, precision continuous spot welding (imitation laser welding), tungsten argon arc welding, and pulsed tungsten argon arc welding. Welding (a function only available on mid- to high-end argon arc welding machines). The welding machine can be used for multiple purposes. It can be used for cold welding, it can be used as a tungsten arc welding machine, and it can be matched with automatic welding and use an automatic wire feeder to achieve semi-automatic welding.

5 Differences in ease of use: All welding parameters of the cold welding machine are controlled by the microcomputer of the welding machine. The solder joints are uniform and beautiful, and the operation is simple. There is no need for a professional welder to operate. People with no operating experience can easily operate it after simple practice. Can produce very good welding results. The technical requirements for welding personnel are lower than those of tungsten arc welding. It reduces welding technical requirements while improving welding quality.
