The best Tack welder?

Are tack welers worth the expense? Which is best?


Joyal I feel is the best, it’s a commercial unit not a toy like
other units I have tried. I understand this is what Stuller uses in
their shop although they sell another brand. This units new sell for
approx. $2500. If anyone is interested, Joyal is in north New
Jersey. I do have a unit for sale, I got a laser and don’t have a
need for it anymore. I’m asking $1500.
