PUK U3

PUK U3 е универсален ВИГ-микроимпулсен заваръчен апарат, подходящ за малки и големи производства, дизайнерски студия, а също и за развойна дейност (R&D).

The innovative and proven welding technique that the PUK U3 employs, enables the user to place precise welds and apply fine amounts of metal on all weldable metals and alloys. Welding energy is only applied very locally and affects the work piece only briefly, this makes the PUK U3 especially well suited for applications which could, in the past, only be successfully welded using a laser welder.

Advantages of the PUK U3:

Arc welding with impulse modelling

To maximise the benefits of TIG impulse welding, the PUK U3's welding impulses, in the standard mode, have been specially modified and modelled to produce optimum results on most alloys and special metals.

HF-pulse welding

The high frequency pulse welding combines several useful attributes. With this process, welding impulses that have already been modelled, are overlaid with a high frequency oscillation of 5 kHz. Thus, on the one hand, the arc is "constricted" so that the arc force is increased, on the other hand, the quality of the oscillation is improved measurably; this is especially noticeable on metals which have a high heat conductivity.

Micro welding mode

The precise matching of welding impulse and impulse duration allow micro welds right down to 0,10mm with sheet metal and 0,25mm with wires.

Gap-mode

Here, high frequency pulse welding is also used to positively influence the form of the arc and the arc force.
The "Gap" mode uses a particularly rigid arc to optimise performance when faced with acute angles and deep-lying welding areas.

Resistance welding

With the aid of resistance or contact welding, wires and fixings or jointing elements can be simply welded or attached there where they meet.

Programmable memory

The rate that the PUK U3 welds, adjusts itself to the welding tempo of the operator by automatically regulating the gas pre-flow time.

Operating speed management

The rate that the PUK U3 welds, adjusts itself to the welding tempo of the operator by automatically regulating the gas pre-flow time.

Recall function

The machine automatically saves the settings of the preceding three welds. These can then be simply retrieved at the touch of a button.

Foot switch

As an alternative to automatically starting the welding process, this can also be done manually with the aid of the foot switch.
