Steel Grating Equipment

Description:

QGZP-400-1A and QGZP-600-2A are large-scale steel grating medium-frequency welding machines co-developed by our company and institutes through advanced technology introduced from Germany. The product fills the domestic gap, reaches the world advanced standard and gets several national patents.
Adopting human-machine interface automatic control, the product is of short welding time, high speed, robust welding, and obvious power saving (It saves 30-35% power more than other domestic power-frequency welding machines). The products is of welding frequency of 1KHz, so in terms of 50Hz power supply, it owns functions of high-density current output and high-precision regulation of dynamic and static parameters. It reduces heat and mechanical pressure of electrode and decreases 50% of electrode wear. The support power transformer saves 40-50% KVA capacity more than power-frequency welding machine. 
Welcome clients to visit our factory. Please compare our products with like products in the market and then make your choice.

steel grating machine 
our grating machine adopts advanced intermediate frequency(1000Hz) technology.Its instantaneous electric current is very strong and welding time is short,so it can save appox.30-50% power energy than low frequency(50Hz) grating machine.
Moreover in contrast to low frequency(50Hz) grating machine,its matched transformer can even save 40-50% KVA ,so our grating welder is the first choice you invest.
