Can you post a picture of your mig gun? Looks like a gas issue. Might be plugged up in the gas nozzle.
I have more questions than answers

I agree, but I've run a fair share of mig with no gas due to idiocracy, diagnosed at birth, and that is part of it but there is something more. Another good question is what kind of steel and where did you get it from. Could be some weird alloy that does crazy stuff or has some weird contaminant.
A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none.

Sure, when it is daylight out I will post a pic. When I press the trigger, I can feel the gas coming out. In response to someone else, the metal I am using to practice was purchased at Lowes.



Thanks

Here ya go... Doesn't look like it in the pics but there is an opening around the nozzle the gas comes out of. There is definitely gas coming out of it.

So, that black cap is called the diffuser cover. The diffuser cover prevents spatter from destroying the diffuser when using self shielded flux core wire.

The diffuser evenly distributes shield gas within the nozzle to create a laminar gas pocket around the weld pool.

You have to take that black cover off and put a standard nozzle for that type of gun on to have gas coverage of your welds.

You should also clean the nozzle every so often to prevent blockage and maintain adequate shield gas coverage.

Wow..... you are one hundred percent correct. Just looking through the manual and I found what you are talking about. I don't find the other nozzle anywhere. Going to lowes to see if they carry it... Thank you very much.

:) Thanks, but to be fair, it was Polands idea to get the pic.

You should be good to go with some clean steel. Happy welding.

ps. You'll want to turn down those settings back into a more normal range for that wire too.

Yesterday watched a video about his welder, the boring guy there stated, that that machine comes with flux core tip on gun, as I have never welded flux core, kept my 2 cts in pocket.

The video -> https://www.youtube.com/watch?v=x6WzZ_LoDSg

That is pretty decent. I'd try stacking them side by side for a nice even pad. From there its on to different joint configurations, positions, bevels, tube, pipe etc.

A nice bead is like the keys to the kingdom. Once you have that, you can take it as far as you want.

that is a pretty common mistake when you are in a hurry to play with a new toy, I did the same thing and had to go back to the manual and when a friend was telling me about his problems when he was knocking the new off of his 180 he had done the same thing, it's amazing what a difference it makes. I read the manual a little before firing up the next machine.

good welding.

the heck with the duty cycle on the welder, tell me about the duty cycle on that grinder !!

I have watched everyone of his MIG videos. They have been a big help....
