DN Series Pneumatic Spot Welding Machine

This air-operated spot welding machine adopts high-quality silicon steel and compelling water cooling circulation system.
This series of welding machine is a new generation of welding machine,pneumatic pressurized and precision controlled using new electronic control devices,developed by our company on the basis of sufficiently researching the resistance-welding machine.Four parameters such as current-rising time,current value,current-sustaining time and pressurizing time can be steplessly adjusted,so as to make the welding spots to have controllability and uniformity.lt can be used for the welding of various steel plates/sheets.lt has the following advantages:firmly welded;little spatter;high welding speed and high working eddiciency.
