Description:

DN2 series integrative hanging spot welding machine,also known as integrative spot welding machine,it integrate the main transformer and the welding clamp together,it has aluminum alloy body,with small volume and large output,high efficiency and energy saving,light flexible,etc characteristic.while the machine operation can be done horizontally and vertically rotate 360 degrees. The major advantages of integrative spot welding machine is saving a lot of energy and one-time investment costs ,as well as the consumption cost of wearingparts.

It has a flexible light weight body ,stable and reliable.

Application to a variety of low-carbon steel,low alloy steel,stainless steel,galvanized steel,sheet and bar.
