I'm running a lincoln 140 with .035 Flux lincoln wire, but I feel I can use a better wire, what does everyone use??

does your rig have a purge setup? if it does, get a tank of argon and some solid wire. huge difference

I can hookup a tank eventually my goal is to run Flux with a argon co2 mix but at the current moment I can't get a tank the local supplier decided to fudge up something with their tank rentals

I haven't really messed with flux so I'm not much help. I use solid wire and 75/25% mix at home and co2 at work, definitely prefer 75/25.

Buy your tank if you can in your area. I own my own acet./oxeg., as well as my argon bottle. The argon bottles are only approx. 100 bucks + the gauge setup.

I can get a tank problem is no one will fill it. I've got arc3 gases here but they only fill their own tanks

Flux cored wire doesn't weld bad as long as you have your Polarity right . Alot of the machines are sent set up for solid wire / gas welding .. For flux cored wire , make sure you switch your +&- cables inside the machine. Lincoln makes an Innersheild NR-211-mp wire that welds very nicely . I keep a few rolls in my service truck for my spool gun . Pros of flux core vs solid wire is mainly the penetration . Whereas solid wire with a straight CO2 will give you the best penetration, but a not so nice weld appearance . 75ar/25co2 mix is the most common mix out there and just about everyone uses it . ER70-S6 is a nice all purpose soild wire also . If you want a really nice weld appearance , we use a Steelmix .. I think it 90% argon , 7.5% co2 and 2.5% o2

Btw i carry an ASME pressure vessel cert and a AWS D1.5 Bridge cert .. Feel free to pm any questions about anything welding related ..

The polarity is correct first thing I did when loading my wire and I also use the Lincoln 211 but it really seems to be sensitive to mill scale or any contaminant. It throws weld berries like no tomorrow! Also I found out very quickly it does NOT like to arc on any Flux.

Mig Flux core isn't bad, Just remember to Clean clean clean. The cleaner it is, the better the welds.

Yeah I've figured that, just some UGLY looking welds. Granted I am by no means a professional, but I'm learning when I can.
