DND3 Mobile Single Side Spot Welder
Email this page Share
- It is for single point, manual spot welding, made up of gun and clamp through welding structure formed by welding circuit, achieving the purpose of spot welding. Cooperating with the micro-computer controller, it can ensure the stable welding current.
- The welding machines can be installed on the cart, which could be movable. And it can also hanged like DN3 series welding machine for moving freely. During the welding, the workpieces are static, while the welding gun is movable. It is safe and reliable and flexible, which can achieve all-round welding requirements completely.
- The welding machine can be used in the automobile welding, especially for welding the bus skin and the structure, and the sheet welding such as metal box, door or casement.
