Yes. Also known as “self-shielded”Hi,
By ‘gasless’, do you mean flux cored?
You know, I’ve read this before. Is it quality of wire?They type of wire makes a huge differance
Oh this is fascinating!!! Thank you for this. Firstly, I didn’t know that about needing to reverse the polarity (still don’t fully understand this?) and secondly, it’s the destructive tests that I’d like to compare with MIG.I tried some Lincoln Innershield NR211-MP yesterday (yes I vanished into the shed on christmas day), I'd bought a small spool just to try out, and I was pleasantly surprised. You have to reverse the polarity of your welder or it makes horrible spatter everywhere.
Once I got it dialed in (the Lincoln charts were spot on for WFS and voltage) it makes a lovely soft sound, a very visible weld pool, and made some very nice beads with a soft slag covering. You can weld any position with it too - I did overhead and vertical up with no problems like you normally get with solid wire.
I cut and etched one piece and it was biting into the metal nicely, unfortunately it failed a bend test but I think it was more to do with too small a bead size.
Friend of mine was using a cheap Harbour Freight flux core 120 amp wire welder, welding some brackets on his hot rod frame. He was about to weld on a scruffy bit of metal, with rust and some paint splitter on, and I fully expected the weld to fail miserably.
Nope, he put down a very solid looking run, lots of spatter and noise, but it was a good weld. If I had tried that with my Sip 130 Mig the bracket would simply have fallen off.
Pretty sure they do for exterior work.I was going to (and still might) post a thread asking why welding production companies don’t use FC instead of MIG, if the benefits are so many?
Think I should do this?
Gosh, not one of the ones I know. I’ll have to get asking.Pretty sure they do for exterior work.
