Pneumatic AC Pulse Spot Welding Machine 50 KVA For Stainless Steel

Hwashi Pneumatic Ac pulse Spot Welding Machine for stainless steel

DESCRIPTION OF SPOT WELDING MACHINE

Medium frequency inverter DC resistance control system: Refer to the following picture, the three-phase AC current has been rectified into DC. Then convert into medium frequency 1000Hz square wave and connected into primary of welding transformer through inverter circuit which is composed of IGBT. After the rectification through welding transformer, the current become DC with small pulsation and being supplied to electrode for welding. The inverter will adjust the duty cycle rate of IGBT according to the feedback of primary and secondary welding current so as to achieve constant current during welding process.

SPECIFICATION OF SPOT WELDING MACHINE

FEATURES OF SPOT WELDING MACHINE

Multiple times of continuous discharging, finish welding at one time, firm connection.

Be able to achieve welding and cooling at the same time to ensure the welding intensity of products.

Compared with the normal AC controller, MF controller has the following advantages:

1. Advanced welding machine, adopt principle of MF inverter . Change the three phase AC power into DC power.
2. Welding current is DC , no inductance , higher heat input and output efficiency , more reliable and stable welding quality
3. Three phase load balance, power factor is close to 1
4. Intelligent digital controller, more precise and faster control of the welding current. The adjustment precision is 20 times higher than the AC machine
5. Reduce the production cost, save energy, reduce the requirement for cables and maintenance cost, improve the induction factor.
6. Store energy in a special inverter, more adaptation to the fluctuation of the power grid.
7. Smaller size and lower weight of welding transformer, one third of the AC machine .
8. Be able to weld aluminum and galvanized material product
9. Especially suitable for welding three-layer metal sheet or very thin product
