Features of Condensed Type Resistant Welding Machine

• Condensed type just needs 1/10 - 1/30 current if it is compared with alternative current type. It can make use of the power efficiently. It is a power-saved type welding machine.
• Very less hot warp and oxidization save the processing in follow-up steps.
• Stability：Less welding tolerance conforms to JIS vehicle specifications.
• Economy：The consuming parts such as copper electrode is very less, and power consumption is very less. It reduces the operation cost.
• Durability：The pressure adding device and the semiconducting charge and the discharge circuits are considered to keep their superiority.
• The key components are imported from Europe, the USA and Japan. Among them, the pneumatic components are made in Japan, and SCR (Silicon Controlled Rectifier) is a product made in Europe, the USA or Japan. The condenser is same as the condenser used in Japanese.
• Machines. It is a storage type condenser for special use on instant charge and discharge. The control system is made of the USA or Japanese components.
  
  In addition to above features, the non-iron metal and the different kind of metal can be soldered together. It doesn't need auxiliary material, but increases efficiency if it is compared with the conventional method of rivet and solder. It is very helpful for the enterprise to save material charge and the salary.

The principle of condensing type resistor Welding machine

As Figure 1 shown, store the power needed for welding into the condenser. Then, discharge this power instantly into the welding container. It will discharge a large welding current. It is like to pump the water from a well to a bucket. Then, pour the water suddenly from the bucket.

Therefore, it just needs one tenth or less current to finish the work if it's compared with the alternative current type welding machine. Besides, the current of instant electricity discharge can be used efficiently. Its heat efficiency is better than other welding types.

The condenser can be charged 475V maximum. The charge voltage can be adjusted to meet the need of welding current. The charge voltage is controlled by semiconductor, so the charge voltage is not changed even if the voltage is unstable. You just need to set one time, and always have a fixed welding current for the welding needs.

• Air control cylinder construction and solenoid valve.
  Air control cylinder together with solenoid valve, with no-feed oil dry bearings with minimum friction resistance, quick response, to increase the unit punching speed and reduce air flow loss.
• High-Performance air compression components (Air F.R.L units)
