NB series crystal gate tube control CO2/MAG auto welder (welder, welding machine)

Detailed Product Description

Technical Characteristics:

1. It adopts unique assisted DC reactor to improve the frequency of short circuit to small current area with stable and soft electric arc; reduce the frequency of short circuit to big current area with little splash and excellent welding performance.
2. The application of high speed and high precise output control technique to realized multi adjustment and keep stable output even if the electric net or pressure fluctuated or the round environment changed.
3. The circuit of time procedure control and various are-receive treatment function control should adopt deep film circuit with less component of plug board, high dependability and completed function.
4. It has perfect over-current, overheat protective circuit to make sure the safety of welding machine.
5. Good control performance, strong loading appliance, adopts advanced feedforward technique and changes the welding performance, reduces the splash and improve the welding line moulding.
6. It adopts balance reactor with center, to change the welding characters easily.
7. The welding power includes various external control signal, applied for various automatic welding or robot welding.
8. It is suitable for the thin, middle and thick welding plate with the thickness of 0.9 mm above.
