If the wire balls and acts as if it is going to burn back to the tip, increase speed. Starting with both voltage and wire speed at the 12 oclock position will get things started.įrom there, adjust wire speed and try to get a a good smooth sound with no stubbing and as little spatter as possible.
I used a chart on the inside of my welder but if you dont have a chart, you might have to get a piece of scrap and start trying things. Getting voltage and wire speed balanced is key. There are other self shielded wires with different chemistry in the flux that have better properties for multi pass applications but that is a conversation for another day. Home Depot, northern tool, and Tractor supply is e71-t11 selfĪ popular self shielded wire is Licoln Nr211 but Hobart and others make similar wire called Fabshield 21bĮ71t-11 wires are light duty wires designed for single pass welds. There are many different classifications of self shielded fluxcore welding wire but a very common type of flux core wire you will find in stores like Although sometimes its a good way to prop for tack welding. I found that puzzling.īut since no shielding gas is needed, a nozzle is not needed either. My first real encounter with fluxcore ( other than reading about it) was on a construction job.Ī sheet metal worker was welding on some brackets for duct work and he didnt have a nozzle on his mig gun.
#FLUX CORE WELDING PLUS#
Not needing shielding gas is a big plus for some folks. Wire mig but self shielded flux cored wire does not require Self shielded FluxCore welding does require some cleanup.

Like welding over light rust on a muffler, or outside when the wind is blowing.or for carrying to your brother in laws house to fix a lawnmower deck. Self shielded flux wire is good for certain jobs. In this video, and on this page, I am only addressing the Self shielded type. There are 2 basic types of fluxcore welding. Fluxcore welders never use shielding gasĪll of the above misconceptions are dead wrong.įlux Cored welding is used for high rise buildings, ship and bridge building, pipe welding, and more.Fluxcore welding is not a high quality welding process.Fluxcore is only used for those cheap welders you see at Harbor Freight and is not really good for much.Here are just a few misconceptions of fcaw: Maybe thats why there are so many misconceptions. Most folks only exposure to flux core welding is what they have seen in a small garage or muffler shop. Flux Cored Welding for Boy Scout Merit Badge using a Hobart 210mvpįlux Cored welding is often looked at as being inferior to bare wire mig.īut it aint wrong.
