Versatile seam (rolling) Welder,applications ranging in Household appliances,auto,and other metal working industries.

 The following shows part of the roll seam welding products:





Seam (rolling) welding machine is an envolving of spot welding machine. it used circular wheels replace the dot welding electrode rolling and continuous or intermittent with continuous general current pulse, formed by a series of weld seam welding joint composition. when the dot distance is large. the welding form is similar to welding discontinous. called rolling dot welding. it can improve the production effiency. when the dot distance is small. the melt nuclear folder overlapping 1/3 of melt nuclear diameter to get a certain intensity air-tightness weld.

Performance characteristics:

1)  Use intelligent Microcomputer single piece controller. achieve pure digital setting. online computer program. LED digital display. stable performance. program online easy to repairing.

2)  Use intelligent Microcomputer control welding system. voltage fluctuation automatically welding current compensation. guarantee welding stable.

3)  Use digital circuit control. selected components from famous factory all over the world. make sure equipment can long-term stable and reliable running.

4)  Use SEMIKRON, IXYS or IR control. high precision, long life to achieve high stable control for current.

5)  Transmission ZWZ use the current newest foreign mercury conductive technology. advanced technology. transmission and conductive performance are all very good.

6)  Welding rolling wheels used alloy copper material made in Japan. high hard and good conductive performance.

7)  Xi steel sheet with Japanese high-purity refined welding transformer.a good magnetic conductivity performance.low power consumption.strength is more stronger and stable.

8)  Welding mold and machine connection to connect with mosaic, loading and unloading easy and fast.

9)  Welding power can selected AC pulse, secondary rectifying, capacitor stored energy.

Material configuration:

1)  Use SEMIKON, IXYS or SCR control. High precision and long life .

2)  Pneumatic parts with Taiwan and Japan reliable performance.

3)  Motorla integrated circuits used by USA.fast reaction. stable performance.

4)  The electric devices are Japan's Mitsubish or Omron components. service life and performance are very good.

5)  Xi steel sheet with Japanese high-purity refined welding transformer.a good magnetic conductivity performance.low power consumption. strength is more stronger and stable.

Suitable industry:

major supplied in automobile shock obsorber. thermostat probe. battery nickel belt. oil radiator heaters. Power capacitor. Mesh frying basket industry. pump industry. canning industry. barrel industry and so on.
