PUK C440 Pulse Arc Welder


#1

Is anyone using the PUK C440 on sterling silver? If you are, please let me know how it works. If you prefer, contact me off line at rmeixner0526@gmail.com. Thanks…Rob

I use a ag/pd alloy with my PUK 5 (recommended and works better). Silver is terrible to PUK, it reacts the opposite way to gold and other metals. Best try to PUK it fixed and solder the rest.
