Precision TIG micro arc welding machine
Non contact welding, which can be used for precise welding of high melting point metal and different metal
- do not need to exert pressure welding, also can realize precision welding in small space.
- can be arbitrary pulse waveform control current in short interval, so as to achieve precision micro
Small parts of the arc welding.
- displays a list of functions available, can display the last 10 RBI data for welding, welding quality
Analysis and management.
In two kinds of discharge modes are available: [single] [] mode pulse wave mode.
In memory of 15 set welding parameter, welding current and discharge time monitoring and alarm
Function.
- equipped with automatic repeat arc function; I/O interface configuration rich, can be used with automation system.

Widely used in: all kinds of coil wire welding; tungsten light source device for the end face processing and welding of copper material components.
