Product Description
Portable spot welding machine uses the resistance welding method in which welding parts are assembled into lap joints and pressed between two columnar electrodes, and the base metal is melted by resistance heat to form solder joints.

Working Principle
The workpiece is pressurized and energized between the upper and lower electrodes, and having resistance welding.
When the resistance of the welding part is R (Ω), the welding current is I (A), and the power on time is t (sec), according to the formula: the current I that the metal material with a certain resistance value R passes through within a certain time t heats up due to the resistance, and the heat generated is Q. The metal resistance current is used to heat the molten metal, and then the metal is cooled, crystallized and connected under pressure. This is called resistance welding.
Welding Arm Can Be Customized
Overview of product structure
This series of welding machine is a portable mobile spot welding machine, equipped with a three degree of freedom mobile rotating device, which is suspended on the truss through a spring balancer
The welding machine can move longitudinally and transversely through the longitudinal and transverse sliding rails, and the vertical movement is carried out through the spring balancer. Swivel ring and boom bearing realize that the welding machine rotates around the horizontal line in longitudinal and transverse directions. The welding machine rotates in a vertical line with the help of a suspension wire rope.
