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)
    Explosion-resistant casing is fitted on the outside of the filter and oil feeder to prevent broken, and to protect it from out-side impact.
    The filter and oil feeder cup can be dismounted to facilitate cleaning and maintenance.
  • The cooling tubing employs 3/8" bronze tube compulsory cooling cycle circuits
    All cooling water pipes of the transformer, SCR and electrodes will have excellent cooling efficiency,with additional temperature rise automatic cut-off switch to completely avoid burning the transformer, SCR in case the water supply is interrupted.
  • High conductivity secondary re-circuits
    Secondary side-welding recircuits made by bronze, low resistance and well-conductivity.
  • Safe and reliable pedal switch
    Sturdy and safe pedal switch with quick starting and easy installation starting voltage DC 12V which can be used safely.
  • An optional press adjuster is provided for upward and downward adjustment
    To respectively adjust the rising or lowering speed and impact during the pressurizing progress, to obtain excellent welding quality and speed.
  • Central air exhaust method to improve working environment
    Concentrated exhausting system will not only reduce the exhaust noise, but also reduce oil mist spraying, to maintain clean working environment. (Fitted with exhaust outlet to exhaust air to outdoors.)
  • All series with micro-computer precision control circuit
    Micro-computer control device: precision control, no effected by unstable power supply condition.
  • Transformer of excellent current conductivity and of minimum electric loss
    Secondary circuit with high conductivity, a low input will produce output with powerful current with minimum power loss and low facility cost.
  • Welding current circuits with adoption of SCR no-contact-point switch
    Main circuit switch employs no-contact-point SCR to increase high welding reliability and avoid accident caused by poor connection and save maintenance and repair expense.
    Even under rigorous conditions, it will still assure stable welding current to obtain consistent and steady welding strength.
  • Solid Frame Structure
    Sturdy body construction, excellent adaptability, reducing the electrode deviation during process, increase the welding quality, and reduce the shock and impact noise of the machine body.
  • Both interior and exterior of machine are processed with coating
    Coated with powder burnt paint after acid phosphate to extend the life time.
