Two, full digital control, simple operation, ordinary personnel can master welding skills by simple training.
3. Good repair quality: whether it is repairing aluminum alloy, copper alloy, cast iron and other metal materials, the combination is firm and not easy to fall off.
Four, large power, fast repair speed: the new generation of SH-M series cold welding machine has 3500KVA and 4500KVA two kinds of power for choice, improve work efficiency, save time.
5. Small size, light weight, easy to carry and move.

For a long time, there is a phenomenon of high scrap rate in casting industry. The scrap rate of common cast iron parts is about 7%, complex parts and high-grade parts are about 10% to 15%, and aluminum alloy die-casting parts are about 8% to 15%. The defects mainly focus on the porosity, trachoma, burr, crack, lack of material and scratch on the surface or inside of the casting. About 80% of these defects can be remedied by repair. When the workpiece products have small defects, the use of argon welding and other methods in the past to repair the workpiece will often produce deformation, or even hot crack, defect area increase and other phenomena, because of the lack of ideal repair effect and directly scrap, directly bring a lot of economic losses or delivery delay.Multi-metal repair cold welder
Electric spark cold welder is a repair equipment invented in the early 21st century. It uses the principle of high frequency electric spark discharge to repair the workpiece without heat surfacing. Because of the welding repair process in the workpiece produces very little heat, and is called cold welder. Cold welding machine through technology import localization has been basically achieved in recent years, has been in domestic die casting defect repair, artifacts, and wear/casting repair market has gained popularity, widely used in mould industry, foundry industry, electrical manufacturing, medical equipment, automobiles, printing, shipbuilding, boiler, building, steel structure, bridge construction and other industries.Multi-metal repair cold welder
The main characteristics of EDM cold welding machine are: small heat affected area, small damage to the base material, no stress concentration, deformation, crack, annealing, quenching, small color difference, simple use, ordinary workers can operate and other advantages. The welding strength of the base material and the repair material is high, which can withstand the mechanical processing such as turning, milling, planing and grinding, and is not easy to fall off. A wide range of metal repair, the vast majority of conductive metal materials can be repaired. In addition, the cold welder is light in weight, can be repaired on site, CNC intelligent adjustment, simple operation.Multi-metal repair cold welder
