The CRUXWELD PulseGem 100 is a jewelry spot welding machine that makes tiny, argon-shielded pulse-arc welds with a fine tungsten electrode. Clip the piece, touch it to the tip and the pulse fires on contact — for permanent jewelry, chain and ring repair, and dental and orthodontic work.

Closing a permanent bracelet on a customer’s wrist, re-joining a broken link or tacking a wire on an orthodontic appliance — these joints are millimetres across and sit next to stones, solder or skin. A flame heats too much; the PulseGem 100 does not.
It strikes a short pulse of arc — 3 to 30 milliseconds — from a sharpened tungsten electrode under argon, so the heat stays in a pinpoint. You set the power and time, or pick one of five presets, then touch the work to the tip. The weld fires on contact and the electrode retracts.
The retract (deflate) time is selectable — 0.5, 1 or 1.5 s — to suit your hand speed.
