TIG DC pulsation welding implemented with low frequency (5 - 300 HZ) and high frequency modulation of welding current (15 000 Hz).

 

The first one is used to form the weld, and the second one – to stabilise and concentrate arc.

Besides, two high frequency (1000—15000 Hz) welding modes which are required for independent fusion of filler and placing melted filler into the weld may be used.

In order to fuse electrode material, especially when welding thin sheet metal, more energy and more stable arc are required, because the welder feeds the filler with its hand.

 

As the result, the electrode is positioned inaccurately. It is reached by high frequency modulation with high level average current of basic pulsation.

 

It is easy accurately to place melted metal with a concentrated arc which is generated by using higher frequency of pulsation welding (up to 15 000 Hz) and low level of average current of additional pulsation.

STANDARD PACKAGE
  • Stable arc is less sensitive to changes in gap;

  • Confident control of weld area, penetration depth, and weld shape in all spatial positions;

  • Smaller area of thermal impact and risk of incomplete fusion.
