1. These are 21 sets of spot welding machines. Among them, there are 5 sets of CNC pneumatic spot welding machines, and 1 set of carbon dioxide(CO 2) protection welding machine ;
2. The spot welding machines adjust the electric current intensity according to the thickness of the steel plate so as to assemble together the various parts of one product, such as door reinforcement, side

   hanging bar, hanging base etc.The thicker the steel plate, the stronger the electric current .We have professional operaters with rich experience.They can ensure the smooth surface of welding products .
3. CNC spot welding machines can precisely adjust the electric current intensity and the length of the welding time, so the welding fastness is assured;
4. CO2 protection welding machine fuse the welding wire at an instant, then isolated from oxidation to prevent air bubbles, so as to protect the products. It is mainly used for welding door angle and

   some parts that are not easy to weld.
