how much wind is to much?  i have some work to do on an old truck frame and i will be working outside.  i just bought a hh 187 and it came with flux core wire.  should i just go a head and use this or invest in a bottle?   i would prefer to stick with the flux core for now so i don;t have to buy a bottle.  will the flux core be sufficient?  thanks.

Reply:so are you thinking somewhere between 5 to 10 mph?  i understand your concern and it is well taken.  this vehicle is a $400 POS that i will use on the farm.  a good runing toyota with a bad frame.  typical.    this is not my first welding experience.  i've doen alot of stick welding.  i've alslo done quite a bit of mig welding.  just always in a garage without the threat of a breeze.  that is why i was wondering about the effects of the wind.  i'll keep looking.  thanks
Reply:I'd say that as long as you don't have to lean into it, you should be ok as far as wind and flux core.BTW, that's mighty bold of you to use that handle on a welding forum.Good luck with your project!Two turn tables and a microphone.
Reply:Originally Posted by DSWIf you have to ask these questions, you probably shouldn't be welding on vehicle frames. There's a lot more to it than pointing the gun and squirting metal at it. This isn't a beginner DIY project.First you need to learn to do code quality welds in position. Most new welders can't make decent welds in the flat position, let alone vertical and over head. This will take you more than a weekend or two of practice. Expect to spend some serious hours under the hood burning wire. If this is to be done on the vehicle, also expect to spend some time on your back practicing this under real world conditions as well. Second you need to do some research and find out just what the manufacturer recomends and the procedures to do this. Many manufacturers don't recomend welding on frames on newer vehicles. The frames are high tensile alloy steel and are often heat treated. They require special wire/rods as well as specific preheat and post heat requirements. Just welding away on these with any old wire without the proper procedures will destroy the frames structural integrety. It's no longer like the old days where it didn't matter, and hasn't been that way since maybe the 70's.Simplest way to "fix" a frame issue is probably to just buy a new or decent used frame and use that. If thats not an option, you need to look for a shop thats familiar with these procedures and have them do it. Chances are by the time you invest in the training and practice to develop the skills this will require, you probably could have bought a new truck and still saved money.

Reply:build a windbreak,a tarp or a sheet of plywood should be okay unless its tornado time...
Reply:i just picked out my handle because i had a hobart welder.  i'm not trying to insinuate anything.  experienced yes, expert absolutely not.  sounds like i need to by a bottle.  i'lll check into this next week.  i'll practice with the fluxcore to get the feel and go from there.    DSW, pm sent.  thanks
