Getting porosity by using Flux Core Gasless welding wire …

You also need a different polarity setting on the machine to run gasless flux-cored wire, so this can’t be run on a standard gas only mig. (you need the Dual-Purpose ‘EN’ models). In practice you will find that the standard gas set-up runs much better, especially on thin sf.

Flux core wire - Miller Welding Discussion Forums

Polarity Hey Metalmeltr, Ok as I understand you only need to rev polarity on gasless wire and only gasless wire That how I read it. I hope this helps. I run dual sheild and mig wire on the same mach works fine. I run .045 I also heard of .035 dual sheild but I like .045

Gas metal arc welding - Wikipedia

Flux-cored wire is considered to have some advantages for outdoor welding on-site, as the shielding gas plume is less likely to be blown away in a wind than shield gas from a conventional nozzle. [59] [60] A slight drawback is that, like SMAW (stick) welding, there may be some flux deposited over the weld bead, requiring more of a cleaning process between passes.

How to use a wire feed welder without shielding gas

It’s necessary because the hollow flux-cored wire is a lot softer than regular MIG wire, with that comes the problem of damaging the flux-cored wire, it also affects the feeding speed. Also, you need to change the polarity of the welder form DCEP to DCEN, meaning from electrode positive to electrode negative.

What is Flux-Cored Arc Welding?

Flux-Cored Arc Welding was introduced in the 1950s. It is a process that is very closely related to Metal Inert Gas Welding. Both processes use similar equipment and continuous wire feeds, and both MIGW and FCAW use the same type of power supply.

2008/9/10· Hello Kenny, by your description I am making the assumption that you are using a self-shielded flux-cored wire to weld these rails. If you go with the "copper" colored wire, this would actually be considered "solid wire" and has a different classifiion and requirements than the wire …

What’s The Best Flux-Cored Wire for Mild Steel? Found it!

To be honest, I am not a big fan of FCAW method since I mostly work indoors and flux-cored welding process produces a lot of nasty fumes, (It is important to work in a well-ventilated area or even better, in the open air) but because it seems to be an upcoming trend among beginners, since it is a very forgiving and fairly cheap welding method, I did some digging to find the best wire for Flux
