Multitack

 The Multitack system makes it possible to reduce heat output while joining two light gauge parts.

This function makes it possible to minimize the heat output when joining two gauge parts.

The series of arc strikes at short time intervals allows the material to cool during the pause between one strike and the next and thus minimizes its deformation. The facility to adjust the frequency of the series of arc strikes in the time unit makes it possible to adapt the electric arc to the welding speed and the join geometry.

 

TIG DC Standard Welding

 

The continuous welding current supplies a continuous energy that prevents the workpiece cooling and causes its overheating with consequent excessive penetration and deformation.

Using a pulsed current it is possible to reduce the overheating’ s effect, but not totally, in fact the arc remains always alight and so it keeps on to supplying both power and heat.

 

Multitack Welding

 

The series of repeated arc strikes at short time intervals allows the material to cool during the pause between one strike and the next.

The Adjusting of the arc strikes’ frequency in the time unit, makes it possible the optimizing both of the welding penetration and execution speed, above all the heat output remains under control with consequent reduced workpiece’s deformation.

 

Multitack Applications

 

In the fillet welding it is possible the use of Multitack which allows to achieve excellent results. The weld remains white and without any oxidation, thus prevents the acid treatments which often must be applied post welding.
