I'm having problems with the wire feeding on my thermal arc 211. It seems to be sporadic with the feeding consistency. When welding the wire wire seem the get either held up or burn back. Using the recommended setting for .30 flux wire seems to be way to hot or the feed rate way to slow. I'm using a 2 pound spool of us forge that I got cheap. I thought maybe it's the way the spool is wound or possible just the cheap wire not having a consistant metal flux mixture and burning back because of it. I also have problems with the wire breaking off where the wire leaves the welder and enters the lead. I've had problems with that since I got the machine and can't weld for any extended amount of time with out it happening. The breaking issue happend when I was using two pound spools of Hobart .30 also. Wondering if maybe going to .35 on maybe a ten pound spool would work better. Any suggestion would be appreciated.
Reply:.030 in flux core will be a pain. I would go to the 10 pound .035. Unless you are welding really thin sheet metal your results should be much better.
Reply:Do you have the flux core rollers installed on the feeder? They have a wavy groove to grip the wire. Also, be sure the gun connector is deeply seated. Mine wasn't and I would get the same thing. Be careful loosening the thumb screw which locks it in. If you back it out too quickly, it will spin out of your fingers and fall deep into the machine.

Reply:Ended up buying a 10 pound spool of .35 seems to work a lot better. I haven't used flux much flat it welds good in the flat position I tried some in vertical and the amount of molten bits landing on my arms is ridiculous if I were to do it for an extended time I would need a leather welding jacket. I'm guessing this is normal with flux? Also the flux is pretty difficult to chip off and the head doesn't have the ripples in the vertical position that that was it does in the flat and suggestions?
Reply:Flux core is messy. When you say vertical, I assume you mean up. Gravity is not your friend. I almost always find a way to avoid it. I've even tipped the piece.Get a cheap grinder and a wire cup brush. Chipping FCAW slag is maddening. I have three Harbor Freight grinders with permanently mounted tools. One is the brush, the next has a flap disk and the third is for normal grinding. Irving, TX. Epicenter of the Metroplex!Using Tapatalk |
