Old-fashioned butt welding machines are mainly based on contactors. Mechanical aging and wear are the main causes of failure. They can be repaired by replacing switches, contactors, relays, etc.!
Xinxing will choose first-line brand components, such as CJX2 series long-life contactors and NP2 metal push button switches, to extend the mechanical life as much as possible.

Wuxi Xinxing Welding is an enterprise engaged in spot welding, butt welding machines, customized automatic welding machines, and production lines. They are mainly used in non-ferrous metals, wires and cables, refrigeration radiators, home appliance hardware, automobile manufacturing, sheet metal, 3C electronics industries, etc. Develop customized welding machines, automatic welding machines, assembly production lines, etc. based on customer samples, provide appropriate automated overall solutions for enterprise transformation and upgrading, and help enterprises quickly realize the transformation and upgrading from traditional production models to mid-to-high-end production models.

UN3S CNC metal wire butt welding machine is based on the old model UN3. Only the transformer remains unchanged, and the other components are comprehensively innovatively designed and manufactured. The style is novel and unique, both beautiful and practical. It is convenient to move and fix, and has improved performance and longer service life. Butt single-core copper wire, aluminum wire, steel wire, titanium wire and other metal wires to achieve the strength of the base material, which has a lot to do with the use of 33JR controller and thyristor.
What are the new advantages of using 33JR controller and thyristor brain?
1. The old model uses a contactor as a switch and has a life limit, usually an upper limit of 5,000 times. This new model has no upper limit and its service life is greatly increased.
2. The old model uses 8 levels to adjust the welding current, and sometimes there is an embarrassing situation where the current is too high or too small. The new model has 99 levels of adjustment, and can accurately set the two important parameters of welding current and time.
3. The old model will cause sparks to splash, which frightens welders, but the new model can suppress sparks by 90%, ensuring safety.
4. The old model uses a rotary gear. After a long time of use, the handle will age. The new model makes the internal keys of the controller less likely to be damaged.
5. Minor faults in the old model require comprehensive inspection, while the new model will self-diagnose, self-protect and proactively alarm.
