steel grating cutting machine

الوصف

Our company’s products are medium frequency welding, their welding frequency are 1KHz,in contrast with the working frequency of *0KHz,they have such advantages of extensive current out put ,accurate dynamic and static adjusting ,electrode heat and mechanical pressure reducing. The electrode wear and tear can be *0 percent less. The details with following

1.    High efficiency &energy save .Its rectifier is manufactured in Germany and can directly transmit direct current therefore , the return circuit of welding has no resistance. For this reason, the welding current has been increased , the time can be shorted ,the power can be saved in consequence.

2.    the closed loop control is applied by computer during welding .therefore welding current can be stable even when there are power supply voltage waves and welding load changes. For this reason , the welding quality can be guaranteed.
