The statement below says " up to 3/16" with MIG welding and 1/2" with gas-less flux-cored welding. "

Why can you weld up to 3/16 with normal gas welding and with flux core you can weld 1/2? I thought you would get a better penitration the other way around. Why is this? Also doesn't flux core spatter more?


Lincoln Electric
Pro MIG 180

It’s a portable wire welder designed for use with industrial 230 volt input power, so you can weld on thicker material — up to 3/16" with MIG welding and 1/2" with gas-less flux-cored welding.

Great arc starts make getting started easy.
Wide voltage ‘sweet spot’ gives you a very forgiving arc, so setting controls is a snap.
Wide 30-180 amp welding output range
Unit Includes: Six spare contact tips, Gas and gasless nozzles, work cable and work clamp, Adjustable gas regulator and hose (for argon & Ar-blend gases)

just kiddin man...


ya... it doesnt make much sense to me either... unless it was duel shielded flux core...

there would be pin holes and diddy ***** all in that 1/2" steel without gas...

 

That sounds right.

 

I am not 100% on this, but I believe the extra 1/16th inch of penetration is due to the lack of gas cooling the bead the whole time, as you have when shielding. The flux core bead is going to be a little bit hotter.

 

Flux core is going to be a hotter weld.

In the structural steel industry, flux core is highly considered to be a much stronger weld (especially gas sheilded metal core wire).

Where I work, we are authorized only to use gas sheilded flux core for critical structural joints.

We can weld up to 2" plate with flux core. Theres no way your going to do that with standard ER70.

In terms of the automotive application of welding, standard ER70 wire is more than enough (don't even think about using fluxcore wire).
