Small-scale Spot Welding: This spot welder makes a small welding spot that means it won't damage the anti-corrosive paint on the other side of the panel.
Fast Heat Radiation: The side holes can help the dent puller quickly dissipate heat.The heating of the machine has the function of overheating protection. When the temperature reaches a critical value, the welding machine will automatically stop working, and can continue to operate after cooling. the automatic overheating protection function can ensure the spot welder dent puller work continuously for a long time without worrying about burnout. It features high efficiency, practicality, and reliability.
High precision PCB control circuit board: Microcomputer control, imported components, multi-layer chip technology, dust prevention, moisture-proof, and anti leakage treatment. By presetting expert welding mode parameters, novices can also become masters of gold. The computer automatically memorizes the last operation for the convenience of next boo
Intelligent induction repair technology: Intelligent induction/manual integrated one button switch
Quick heating repair technology: The combination of quick drawing tools and hot spray guns can achieve one-time drawing repair of concave parts of aluminum body
Double grounding design: Fully the current direction of aluminum mesons during the welding process, prevents arc welding, and makes the welding more secure
High energy capacitor: Capable of withstanding greater charging and discharging currents than 1 million times, with faster speed
Automatic adjustment of welding gun: Different studs require different welding forces, so the welding gun pressure can be automatically adjusted according to different studs
Core patented technology: Plug and play pull ring: Plug and play pull ring: regardless of M4, M5, M6 screws, plug and play, greatly improving work efficiency. Avoiding damage and disposal of the pull ring caused by stuck or broken nails.
Fast charging and discharging technology: The super large energy storage capacitor has a large capacity, fast charging and discharging speed, and long service life, ensuring the welding firmness of the machine. The power storage process only requires 0.3S, which is called fast charging technology.
Rapid heating repair technology: (patented technology) Aluminum body has poor tensile resistance and cannot achieve spot welding and direct pulling like iron body. The combination of a quick puller and a hot spray gun can achieve rapid drawing and repair of dents in aluminum body parts.

Notice:
Due to the fact that the aluminum body is made of 1.2mm aluminum material, inaccurate welding power operation can cause poor welding or penetration. When selecting a model, please try to choose a new generation of digital high-precision control models.
Aluminum body has high strength and poor local tensile performance, making it prone to cracking. In order to improve its strength during the body manufacturing process, the elongation rate has exceeded 30%. Therefore, special tools must be used when repairing.
During the repair process of aluminum body, one of the time-consuming tasks after welding the threaded nails is to screw in and out the threaded nails with the pull ring, which is time-consuming and labor-intensive. And the broken threaded nails in the later stage also delay the reuse of the pull ring.
The aluminum body is made of aluminum magnesium alloy, with a melting point of 630-650C. The stress relieving annealing temperature of aluminum magnesium alloy is between 320 and 360 ° C, which can be used for deformation repair. During the repair process, tools that do not exceed this temperature must be used to assist heating. There are also areas with reinforced adhesive connections on the back, and the heating temperature should not be too high.
The firmness of meson welding will directly affect the repair effect. The double grounding point design fully ensures the current direction, avoids arc deviation, makes welding more secure, and thus ensures repair quality.
