MTK-2002

   Capacitor discharge welding machine. Designed for high-precision welding of thin and dissimilar materials made of stainless steel, titanium and aluminium alloys, and even highly conductive materials such as copper, brass and nickel. Ideal for mass produced products in a wide variety of industries: electronics, aviation, space, etc. 

 

Functional features and advantages:

 

  • Enhanced welding current stabilization by changes in supply voltage.
  • Capacitor bank voltage control.
  • Automatic and single cycle operation. Setting-up mode.
  • Welding current is controlled by smooth voltage control and capacitor bank capacity.
  • The two-pulse mode allows providing preliminary heating current or annealing current along with welding current.
  • Weld Quality Monitoring: measurement and display of peak current, peak time, RMS current and electrode force for each weld. Facility to set acceptance limits for peak current to enhance on-line quality assurance.
  • Smooth control of upper electrode total and welding strokes.
  • Adopt pneumatic parts by SMC (Japan) with reliable performance.
  • High current impulses’ stability in terms of amplitude and length ensures that exact power is recharged to every weld joint providing premium welding quality.
  • Particularly low power energy consumption as compared with other RWM types.
