(wisconsin)

how does flux core wire welding differ from regular .045 bare wire.

--------------------------------------------------

Settings and techniques differ.

There can be a lot of difference depending on welding position, thickness of metal , and whether a self shielded fire or a flux core wire that also needs gas shielding (dual shield)

Below are 2 links to Millers welding calculator for both bare wire and flux core settings.

these are good resources for a starting point.
