Jim you are starting to get on my nerves here! what are you a text book welder? I probably use more welding process then you so far in my life! Let me tell you so of the welding I done a few years ago I welded a seam that was about 100 feet or so with FC duel shield 75/25 mix and it was in the winter! I had to use a JLG you know what those are don't you Jim? Well It was a little windy so I manned up JIM I thought out side the text books I got visqueen you know what that is Jim? I use that as a wind break around the rails of the JLG warmed it up with the propane torch and laid BEADS!. You see Jim you have NO EXPERIANCE out side of the text books! but I do! that separate's me from you CLUELESS Jim!

Yep, I'm clueless. So clueless, I'll post a pic of my current MIG rig that I've only had about 8 years.

Hey, wait a minute! You don't use MIG on job sites because FCAW is better... You just said that yesterday!

Please tell us how to use 7018 on aluminum. I'm all ears to learning new tricks dude.

I did mention it. Hauling a power supply, feeder, bottle, and still having to run a power cord up to the work area. SMAW is by far the most portable method of arc welding, it also uses the fewest moving parts.

I stand (sit) corrected. Missed that.

Mig is HARDIRE JIM and FC has the flux inside or you can use it without the flux and you can run it hotter then MIG! so you get more penetration!. Your right I like Smaw and that's what I have in the pole barn! Like I said yesterday mig is ok for body shops and hobbyist but if you have a serious weld job that's need good bead appearance and penetration then you pick stick or FC GOT IT?. Also when you use FC with co2 that's also gives more penetration unlike argon and hardwire.

Both textbooks and real world experience show that MIG can provide penetration equivalent to stick. You can choose whichever you prefer for the working conditions, but penetration is not the issue.

Its comments like this that show you dont have a clue about mig. And make me think you only have experience with 110v machines

Never seen a bodyshop with a 450a mig welder. So just what are those made for?

Again, its NOT about the process, its about the proper welder and consumables.

A mig can run too hot or too cold. So can a stick. There are mig welders that will flat blow through a 1/2" plate as if it were 22 gauge steel.

If you are lacking penetration trying to weld thick metal with a mig, turn up the heat. If the heat is already all the way up, your welder is too small, get a bigger one. Same thing with stick. Would you attempt to weld structural iron 1"+ thick with a 90A inverter stick machine running on 110v? I would hope not. You would choose a machine large enough to do the job. Why can you not admit that you can ALSO choose a mig large enough as well?

FCAW is a variant of MIG and I used the terms correctly in my previous posts. When I was referring to FCAW it was actually regarding dual shield FC, because that's where things get really interesting in the puddle and the heat can be ramped way up depending on shielding gas used.

Hey LD I was not talking you you ? so go sit in the truck and don't touch the radio

Basically the penetration must be sufficient. With more or less penetration you need to choose the appropriate weld prep, or configuration of your weld joint.

To assert that more penetration is better, or inevitably produces a stronger stronger weld seems like a rookie thing to say/write. It's too simplistic, almost ridiculous sometimes. It probably shouldn't enter the conversation without the specific joint type or joint prep included.
