Danny,
The Hobart 140 is listed as "Hobart 140 MIG & Flux Cored 140 Amp Welder". Does this mean that it CAN take flux-cored wire but is not REQUIRED to?
Still learning here... It seems that "MIG" means that the gas is supplied by the welder (via a bottle) whereas with "Flux-cored welding", the gas shield is supplied by the flux inside the wire? I looked up the differences between MIG and TIG but am still a little grey as to when/why I would use one or the other.
Rather than explaining here, pointing me to a good explanation of 'ALL' the differences between these would be sufficient. Thanks for your patience here.
[Edit:] I think I just found my answer at
http://www.northerntool.com/catalog/...guides/welding . A pretty good explanation of the differences here.
