Portable Spot Welding Machine Carry Suitable For Mobile Operation





1. The cheaper price Does not need argon gas protection Particularly applicable to repair the defect of depth is less than 0.50 mm

2. Small size and lighter in weight Easy to carry Suitable for mobile operation

3. Microcomputer intelligent control to adapt to the different thickness of the filling material artifacts and welding head size, power allocation more reasonable, digital display, more convenient operation more intuitive

4. Switching power supply technology, 20% when the voltage is 220 v range fluctuations, still can ensure stable power output, to ensure the welding quality

5. Separate precision welding mode and precision welding head, provide more support for precision operation

6. Suitable for black metal defect repair of workpiece




1. The device belongs to one kind of resistance spot projection welding machine, it is composed of the machinery frame structure, welding transformer, control system, water-cooling welding cable and welding torch, etc. The main electrical circuit adopts the diode thyristor(SCR) contactless switch, to make sure the circuit switch time rapidly, accurately. The control system can precision adjust welding time precisionly, welding repeatability and welding consistency are both very good, also easy maintenance.

2. Compare to the DN Series Resistance Spot Welding Machine, DN3 Series Portable Spot Welder has the advantages of small volume, light weight and other characteristics, install four rollers to the machine to make sure it can move conveniently, furthermore no need air pressure to operate it. By the 2meters length water-cooling welding cable and hang-held spot welding gun, the operation is quite flexible, convenient. Using different welding guns, it can realize portable clamp type spot welding, single spot welding etc.
