Thicker then you think. Now, move along.

My small tractor service business occasionally requires me to weld occasionally. I use acetylene now but was looking at something more convenient and cheeper.

Requirements:
1. Metal not more then 1/4 inch thick.
2. More portable the better.
3. Hoping to be able to use my honda 2000 watt inverter generator.
3. Rusted metal but I do have grinders.
4. Speed is not a big issue because I only weld 5 or 6 hours a month for repair and fabrication.

From what I see flux core can weld thicker materials using less input. Also can weld without doing quit as much grinding as mig. Are those statements true. Hopefully I could get away without caring around the bottle of gas.

Any suggestions?

what i am wanting to do is have a back up on my truck if i run low on gas i carry plenty of rod and am pretty good at using them but i like mig a little better

I would use gas-shielded fluxcore, if you can. It's an all around better wire then the self-shield fluxcore.

agree I just switched today to a shielded wire today and i am so happy I could just poop. I wish I was not so cheep and would have bought the gas tank along time ago. W00T

Gas shielding is costly. Flux core wire is costly. What is the benefit of putting both together?

I always thought it was one OR the other.

Don't worry guys..... I'm starting a welding course at the local JC in a few weeks.

Man this is a rare thread on this forum. Usually people just check their egos at the door and share their direct knowledge... Lets get back to that!

my experience with 211 is it can crack so i use a 212 045 wire on smaller stuff. i also use 232 068 for larger stuff and for flat out speed. i can absolutely smoke 3-5 stick welders with 232. ive also used 233 but its a softer wire and can back up and birdcage in your drive roller mechanism. so i generally use 232 or 212 wire and that covers everything i do. btw im a structural welder. also do equipment welding. all my welding is outside in gale force winds

I've just bought a new Miller 211 and I am new on this welding area. Just start learning...
Presently, I don't use Gas for welding but use only Flux Core wire. Do I need to change the Polarity that presently set up as: (DCEN)
- Work Clamp Lead connected to +
- Wire Drive Lead is connected to -

Please help me to do with it or just let it defaults to factory set up?

Thanks

If you currently are running DCEN then that is correct for almost all gasless fluxcore wires. On the box of wire it should tell you what polarity to run that particular wire on. If not you can look up the parameters on the web. Most gasless wires run DCEN.
