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.
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.
