 Sanhe Electrical Equipment (Shanghai) Co., Ltd. is the metal surface restoration technology industry's largest companies. The company set research and development, production and sales, technology promotion as one of the professional metal surface restoration technology and equipment manufacturers. 
 Companies in the absorption of foreign advanced technology combined with the domestic industry, the actual situation of the metal repair, research and development for domestic enterprises to use the cold metal repair machine series, the cold mold repair machine series, casting defect repair machine, ultrasonic polishing machine, electric brush and hot spraying machines and other equipment. 
 SH-01 Precision welding is the latest complement the development of a professional for high-precision welding of the welding machine. Inverter and the use of patented technology, so that the welding current and welding time by precise control, minimal current situation can be stable operation. Make even the smallest parts of welding possible. Is a more professional, more sophisticated welding equipment. 
 1. A very small heat affected 
 The unit is sophisticated and promising start and the precise set current (2-200A) time (1-500ms), Yasumasa enter only enough energy for the fusion between the wire and the workpiece, the role will not have too much energy to reduce the influence of the workpiece by the heat to a minimum to achieve the ideal concealment. 
 2. Welding thin thickness 
 Since the minimum welding current and stable operation in 2A, so the minimum thickness of welding the corresponding reduced: 0.01mm. 
 3. Precise welding of small parts 
 The welding current, time to get precise control, the current short-term stable operation can be, and precision small parts can be the ideal welding. 
 4. The combination of a high degree of 
 The welder is welding, the material and the substrate to achieve metallurgical fusion. The combination of extremely high after welding. Applicable to a variety of processing methods, will not be combined with other welding after welding is not strong, fall off and so on. 
 5. Repair welding for different parts of 
 Flat parts of the depression, hole, hole, slit, groove, angular, ridge, peak position, trachoma and general depression around welding after welding. Welding EDM, nitriding and soft nitriding treatment of the mold.
