Tack Welding Machines

Back to Soldering & Melting Gateway

What is a tacking machine? There are 2 basic ways to hold pieces together so that they can be solder to each other.   One way is to wrap them together with binding wire, the other is to tack them.   That's where a tacking machine comes in.  By running a very high energy, low voltage current between the two pieces of metal, a tacking machine "tacks" (lightly welds) the metals together.  A "tack" is not a permanent weld.   It's purpose is to hold the pieces together in the proper position for subsequent soldering.  If the position of the pieces when tacked is wrong, the tack can then be easily broken and retacked,  with no damage to the work.  Most work is actually held in the hand when tacking, so getting the right positioning is very easy and accurate.   It's a tremendous time saver when soldering settings, hollowware, etc. 

These tacking machines also fusion weld-  When using "fusion type findings" and using the fusion offset pencil option, you can permanently fusion weld earring posts, tie tack nails, lapel pin nails, joints and catches, and any other findings that are available with a fusion nib.  These fusion type findings are readily available from any of the leading finding houses that you may be buying from now.

Tacking machines are not stock items (special order) and take about 2-3 weeks to build.  

	Tack I-  Tacks and fusion welds.  For gold, nickel silver or stainless steel.  Tack ear posts, settings, ring prongs, wires, joints, catches or hollowware. Energy: 17,000 MFD @ 12 to 70 volts DC Dimensions:  8" x 8" x 4�" Price:  $795
The difference between Tack I and Tack II-  Their purpose is the same, but their power is not.  Tack I is a lower power tacker and is excellent for gold and a few other metals.  Tack II, on the other hand, is much more powerful and is designed to handle metals that Tack I cannot- platinum, silver, brass, titanium etc. Tack I & Tack II Instructions
	Tack II-  Tacks and fusion welds.  For brass, gold, silver, platinum, aluminum, titanium, nickel silver, stainless steel.  Fusion weld ear posts, joints, catches, tie tack pins.  Tack position settings, joints, catches, prongs chain repairs. Energy: 62,000 MFD @ 12 to 70 volts DC Dimensions:  8" x 12" x 4�" Price:  $1,295

Tack III- The Tack III is designed to perform 3 very distinct operations:

1. Tack II has proven invaluable for the finish welding of one piece cast connector links that are used in multipiece cast bracelets and necklaces.  Bombing and pickling chemicals are typically used to remove fire scale and discoloration created when using torch brazing for soldering of these joints.  By using the technique of welding with the Tack III,  the need for costly and dangerous pickling and bombing operations is completely eliminated.  By simply placing the Tack III's weld pencil tip on the joint and stepping on the foot pedal, you instantly, electronically weld the joint closed.   This process brings the material up to the melting point and fuses the materials together in milliseconds.  Using the Tack III, you also eliminate the need for costly solder paste, solder wire and flux.  The job is much easier and faster with the Tack III so inexperienced operators can now be trained to perform operations that, before, required highly paid solderers.
2. The Tack III can be used to weld closed joints on jump rings and also weld closed cast bails with the same efficiency and process as outlined above.   Repair flat "S" chain without wicking the solder and greasing the links.   Weld bracelet hinges without freezing the joint or removing the stones.
3. In addition to the above operations, the Tack III also serves its original purpose-  to provide a simple method of putting two hollowware shell halves together for soldering.  The old method was wither wire wrapping or using metal clips to hold the halves together.  Wire wrapping is labor intense and using metal clips, if not applied with the proper tension, causes dents and miss miters.  Using the Tack II, the two matched shells are simply held together in your hand and placed on the grounding plate with the tip of the weld pencil at the joint.  When you step on the foot pedal, the shells are instantly tacked together for brazing.

Tack III-  Tacks and pulse-arc welds.  For fusion welding chain links, chain mail, jump rings, hollowware, findings, bracelet hinges, chain repairs without solder.  Tack position findings before soldering to eliminate tweezers and clamps. Energy at 3 levels: 450/3,100/15,000 MFD. 10-9 volts DC Dimensions:  16" x 15" x 7" Price:  $3,900 Tack III Instructions
