3 phase bandsaw question
It seems to me that a static converter would nicely run one of the surplus 3
phase vertical metal bandsaws that I often see on Ebay. But does anyone know if it would also run the on-board blade welder? If not, has anyone come up with a reasonable solution? TIA |
I do not know, but I strongly suspect the on board blade welder runs on
single phase. The reason is that if it were to be a three phase welder, it would require extra hardware to transform the three phase into DC to do the welding.

Why do you think the welder is DC? It certainly could be, but I don't think
mine is. My guess is it's a single phase unit, just as almost all coolant pumps on 3 phase lathes are single phase. - GWE wrote: I do not know, but I strongly suspect the on board blade welder runs on single phase.

Simply pull off two of the three lines and run the blade welder. Use any two of the three..though L1 and L3 are best (the two non generated legs) This does NOT work with a VFD. Use the single phase 220 line before the VFD. (and yes..a VFD works very nicely on a band saw) Gunner Rule #35 "That which does not kill you, has made a huge tactical error" |
I do not think it is a DC welder. But if it were a 3 phase welder, it
could not be an AC welder unless one added a lot of components. It would require adding fewer components to have it be a DC welder, but there would be no advantage and it would cost more.
