Cnc Pro Cheap Aluminum Capacitor Discharge Arc Weld Shear Stud Welding Gun Price

Product Description

Energy storage stud welding is also called capacitance discharge stud welding. The equipment first charges the preset amount of energy into the capacitor, and then when welding, all the energy is released from the capacitor at one time for welding. The welding time is 1-3 milliseconds. As energy cannot be supplied continuously, it is generally used to weld studs with a diameter of 3-10mm.

1. Continuously display the energy storage voltage, which is not affected by the fluctuation of input voltage, and can automatically adapt to the changes of power grid, with over temperature self-protection function.
2. The panel is LCD, microprocessor controlled, and has expert welding specifications.
3. The equipment is light, suitable for mobile operation, and can be driven by conventional power supply.
4. Low heat generation, poor penetrability, little deformation of plates/shallow welding pool, no discoloration of the back, slight deformation or no deformation (depending on the thickness and surface finish of the workpiece, the degree of deformation varies).
5. Suitable for stud welding of carbon steel, stainless steel, copper and aluminum.

6. Application fields: electrical cabinets, household appliances, sheet metal processing, signs, insulation nails, elevators, aluminum curtain walls, electrical sets, mechanical accessories, automobile industry, kitchen equipment and metal workpieces, etc.

Welding Principle

Having the tip of the stud contacts the workpiece and pull the welding gun switch, then the energy storage capacitor is discharged through the tip of the element.

When the arc is ignited, a thin layer of molten metal is generated on the surface of the stud and the workpiece, and the penetration depth is about 0.1 mm.

The stud is inserted into the molten pool, the metal solidifies, and the screw is welded firmly.

Applicable Working Environment and Conditions

This welding machine is allowed to be used under the following conditions:

1. Altitude not exceeding 1000m

2. The environment is free of corrosive gases such as acid and alkali, or other harmful gases and flammable and explosive gases.

3. The ambient air temperature range during welding shall be - 10 ℃~40 ℃.

4. Power supply quality: supply voltage fluctuation range 180-240V
