Acid welding..... Hydro flux acid welder

A friend is selling a Hydro Flux / Agua Weld for fine jewelry

It uses acids for welding and I know nothing about it.

It sells new for $900 and this hydro flux welder is like new and he
is asking $550.

Call Joe at 760 - 2 4 1- 0 8 9 4… He lives in Victorville Calif.

Good Luck
