Gasless Mig Wire 0.8mm

Self Shielded Mig Wire 0.8mm is a E71T-GS  self-shielding steel MIG wire . This self shielding wire is  ideal for DIY, Automotive repairs and maintenance applications use.  You do not need to use gas with mig welding with E71T-GS.

Remember : Select electrode polarity. Flux-cored welding requires DC electrode negative, or straight polarity.

.AVAILABLE ON .45KG, .9KG and a 4.5KG spool  select spool size above.

Self-shielded flux-cored welding can be an excellent process to use for welders of all skill levels who frequently need to weld outside or on dirty material. The E71T-GS  self-shielding is the best wire for gasless mig welder.

What is Gasless Mig Wire?

Self-shielded flux cored welding  is a wire welding process in which a continuous hollow wire electrode is fed through the welding gun into the weld joint. Self-shielded flux-cored welding differs from MIG welding in that it doesn’t require an external shielding gas, such as carbon dioxide or argon, to protect the weld pool from contamination.

Instead, a flux compound contained within the wire reacts with the welding arc to form a gas that protects the weld pool. Another process, gas-shielded flux-cored welding, does require a shielding gas. It’s often used in heavy-duty industrial fabrication and manufacturing and is not typically recommended for beginner and hobbyist applications.

Because the flux creates the shielding gas in self-shielded flux-cored welding, this process does not encounter the weld problems that can occur when a strong wind blows the shielding gas away when MIG welding outside. The flux contained in the electrode also allows the process to be more forgiving of base metal that is somewhat rusty, dirty or otherwise contaminated.

Flux-cored welding does produce a slag that sits on top of the finished weld and must be chipped off, similar to stick welding, and it also tends to produce welds that aren’t as visually attractive as MIG welds. For these reasons, if you own a power source capable of performing MIG and flux-cored welding, it makes sense to switch to the MIG process for welds that will be made indoors.
