Product Description

DN series spot welders have the features as follows

1. The main transformer of DN series spot welder is made of imported cold rolled silicon steel, thus the transformer is less power loss and low no-load current.DN series spot welder adopts pivoting arm, pedal, spring press structure, easy to operate and maintain. The appearance of series welder adopts box structure in graceful form, durable and cheap.

In main circuit of DN series spot welder adopts thyristors as non-contactor switch, quick switch off and reliable. Welding time can be controlled and adjusted precisely, good welding repeatability, easy to maintenance, can realize high quality weld.

Spot Welding Machine, Spot Welder, Spot Welding Equipment DN-35A
1. It adopts lever pressurization or pedal control. Lever pressurization can make electrode move vertically.
2. Upper and lower electrodes can be adjusted inclinedly and its electrode arms can make forward and backward movement.
3. It adopts automatic control integrated circuit of precision numerical control electron for precise control of welding time.
4. It is based on spot welding of low carbon steel, stainless steel and its pressing.
5. Applicable to household electric appliance; Suitable for medium and small enterprises' sheet metal processing.
