[Years] DR-500 multi-multi-point resistance welding welder spot welding Jing Cheng Technology internal service quality external AC pulse point (convex) welder, welding transformer allows the use of single-phase 380V power supply into a low-voltage (≤ 10V ) high instantaneous welding power supply, the output current of low intensity, and then is supplied to the electrode contact portion of the welding member, the contact portion to generate a high temperature heat resistance, and achieve the effect of welding under pressure. Our production of AC pulse points (convex) welder, power has 10KVA-300KVA to choose from, it has the following advantages: safe and efficient environmental protection: 24V low voltage control, in line with international safety standards; shortest welding time is only 0.02 seconds; without Adding lead solder, low energy consumption and high efficiency. Output power: high quality high permeability silicon steel refining welding transformer, output power, can be welded thickness of 7mm +7 mm mild steel and stainless steel. Discharge three sections: the improved stability of the welding of special material for preheating, shaping and tempering, avoiding cold joint caused by a current shunt, sealing, especially for high-carbon steel, special coating metal plate. Applicable industries: hardware, lighting, power switch, wire products, small appliances, copper terminals, etc.
