Our company produced pneumatic AC pulse spot welding machine from5KVA to 800KVA. it can welding 10mm iron. - details see: https://www.machineto.com/wl-sp-75k-ac-spot-add-length-type-spot-welding-machine-10142302

Descriptions:
Pneumatic AC pulse spot welding machine use the common city electricity via action of transformer to reduce voltage and increased current. this low voltage big current across the electrode sent to joints parts of workpieces. due to resistence factors between works produced high temperature.metal was influented by high temperature produced high heat make the workpiece in melting conditions then two workpiece arrived melting destination. Our company produced pneumatic AC pulse spot welding machine from5KVA to 800KVA. it can welding 10mm iron. stainess steel and other matels. it adapt to all kinds of hardware manufactured products.

performance characteristics:
1.welding control system: AC pulse spot weldig machine of our company designed can selected various welding controller.
1.1. WD-10AC: digital circuits, pull codes regulating, single time discharge, calls automatically when the welding current voltage fluctuation compensation. owned current climbing function. gradual increased current can quite effective resist or reduce sparks flying.
1.2. WD-KD3: digital circuits, pull codes regulating, three periods discharge, to special materials can do preheat, melting, regulate shape and return fire treatment, solve the multi-point convex welding in the current shunt caused by welded, loose weld defects. especially to high-carbon steel, special sandwich plates can be welded with ease.automatic welding current compensation comes from voltage fluctuation.
1.3. WD-KD4: Intelligent type Microcomputer control. lots of period discharge. to special materials can do preheat, melting, regulate shape or return fire treatment. solve the multi-point convex welding in the current shunt caused by welded, loose weld defects .especially to high-carbon steel, special sandwich plates can be welded with ease. automatic welding current compensation comes from voltage fluctuation.
1.4. CT-110B: Japan’s miyaji Microcomputer control. lot of period discharge. to special materials can do preheat, melting, regulate shape or return fire treatment. solve the multi-point convex welding in the current shunt caused by welded, loose weld defects. especially to high-carbon steel, special sandwich plates can be welded with ease.can memory 15 kinds welding specification. automatic welding current compensation comes from voltage fluctuation.
2.Control SCR: Use SEMIKON, IXYS or IR control. High precision and long life to achieve large or small current achieve high stable control.
3.pneumatic control system: Use big displacement electromagnetic valve and air composition. supplied gas enough. selected quickly eliminate assemble cylinder. high reaction speed. act according to the circumstance performance is good.
4.welding transformer: Xi steel sheet with Japanese high-purity refined welding transformer. a good magnetic conductivity performance. low power consumption. the strength of welding machine higher 15% than the strength to the same industry and same quality machine. it can welded thick arrived 8mm+8mm low-carbon steel and stainless steel metal plate materials.
5.use safty: Strictly execute 3C standard and CE standard.

Material configuration:
→ Use SEMIKON, IXYS or IR control. High precision and long life.
→ Motorla integrated circuits used by the us. fast reaction. stable performance.
→ Pneumatic parts with Taiwan and Japan reliable performance.
→ all the appliances are entry famous brand. service life and performance are very good.

Suitable industry:
Wire products, hardware lighting decoration, dining kitchen appliances, automobiles, small appliances, small hardware and so on.
