    The following information is from the stuller assembly department: 

    Assembly's feedback on the PUK 111 

    Alloy: 

    Overall the PUK 111 tacking ability worked best on all alloy
    product. Normal circumstances, we cannot tack alloy with the Joyal
    tackier, we use a crutch fixture (More time consuming). PUK 111
    compared to the laser: To get the two parts to attach you have to use
    silver, and most of the time gold wire to tack parts together. Note:
    The reason for using gold wire on alloy is, we get a much better
    adherence between the alloy components without the laser beam
    reflecting off of the wire. The silver wire causes the laser beam to
    reflect off of the wire not letting it penetrate properly between the
    two components. The PUK 111 tacks the alloy together without any
    additional metal needed. 

    Silver: 

    Overall the PUK 111 tacking ability worked excellent on all Silver
    product. Compared to the laser: the PUK 111 works much better due to
    reflections in the silver not letting the laser want to penetrate
    the silver metal. Note: On the Laser you have to place a black marks
    a lot on the area needed to be fused to eliminate reflection. Also,
    you have to increase the voltage to the highest setting. 

    Gold / Platinum 

    The PUK 111 worked excellent on Gold and Platinum for tacking
    components in general, and fusing pins on BBRC hinges. It did not
    work very well when filling pits. Note: Most of the time the tungsten
    probe penetrated the area being filled, basically causing a hard spot
    after clean up.

    Overview 

    The Joyal Tackier works best for assembly on most of the Gold and
    Platinum products. 

    The Laser works best for filling pits, porosity, and rebuilding
    prongs with accommodation of wire to get the job done. 

    The Plasma ark welder works best for production fusion of TBRC pins
    and pearl enhancers. This is due to it's consistent and continuos
    welding capability. 

    The PUK 111 works best on tacking alloy and silver. Next, it works
    excellent on tacking the 170300-tiffany head assembly. On bangle
    bracelet's, we have had success on fusing of the hinge pin. There
    are other similar products that we will be able to use this machine
    to assist in the assembly process. 

    Two drawbacks we have observed are: 

    1. The tungsten electrode loses its shape rather quickly in the
    production process, causing the machine to function improperly. 

    2. Once a component is tacked in place it is very difficult to break
    the tack. This is both good and bad (This causes problems when trying
    to straighten a head or component). 

    Over all we feel that this unit is in its infancy for future use in
    the manufacturing area, and the jewelry industry. I would recommend
    the PUK 111 for the trade shop jeweler who cannot afford the hefty
    price for the large laser unit.
