Kevin W Posted March 9, 2012 Share Posted March 9, 2012 What do yall think about welding stainless with a lincon 125 plus. 1/4 inch by 2 1/2" flat - no gas, flux core? Also we' re using the gun that comes with the machine. What-cha -think?? Quote Link to comment Share on other sites More sharing options...
Scary Mc Posted March 9, 2012 Share Posted March 9, 2012 Shouldn't be a problem. You'll have to do at least two passes so just be sure to clean the slag off between them. Edit: I missed the stainless part.... Be sure to use stainless wire! Quote Link to comment Share on other sites More sharing options...
mike-hr Posted March 9, 2012 Share Posted March 9, 2012 Loaded question. By definition, 'welded' means as strong or better than the parent parts. Are you hoping that less than that will be okay? I'd like to give myself a lobotmy from time to time, do you think a couple beers and a 110 buck knife would work? Quote Link to comment Share on other sites More sharing options...
Kevin W Posted March 9, 2012 Author Share Posted March 9, 2012 Yea , MC Just feeling around last night b-4 buying the stainless wire today. I've actually had sucess welding stainless with mild mig wire, of course it rusts and isn't as strong as it could have been -- DEfinately not the kind of thing I'd do for a customer , but arround the shop, well. Mike, piont well taken. The 125 is only rated for 6 or 7 gauge single pass, but I've been using this machine for a long time and we understand eachother, the machine and I. The little gantry crain I built to move the 50# Little Giant was welded up with this machine - My material rack - my lay out table... I love my little machine ( and would trade it in for a bigger one in a heartbeat ). The material size is in this case determined by form, not function, strictly aesthetic, it is (1/4' x 2 1/2") certianly overkill structurally. Really I guess I was asking about the differience between welding carbon and stainless as far as amperage goes. Perhaps my original post was a bit nebulous. "lobotmy... do you think a couple beers and a 110 buck knife would work? " Maby, you'd think the drill press would be the best choice, but, the handle always slips away at the moment if contact" Quote Link to comment Share on other sites More sharing options...
jeremy k Posted March 9, 2012 Share Posted March 9, 2012 . The Stainless will need more amperage comparatively than mild steel. You may find the limit to your machine quick. Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 10, 2012 Share Posted March 10, 2012 Have a stick welder? A 125 fluxcore wire feed is pretty light to be welding 1/4" 304 without a lot of messing about. I've done too heavy welds with my Hobart 120 Handler but not with fluxcore, I run 75/25 so multiple passes without a lot of chipping are just burn it in till it's full. Frosty The Lucky.

Ten Hammers Posted March 11, 2012 Share Posted March 11, 2012 Fluxcore with a shielding gas, grind the root till clean and top passes. 1/8 proud on the weld. Jeremys point is well taken as are Frostys. The rack on my 63 was built with a Lincoln 100 weld pac and fluxcore and no gas. Single pass (mild steel tubing). Stainless will make a difference yes. Stick would be quick. Quote Link to comment Share on other sites More sharing options...
