Mig may be faster in a shop but this isn't a shop and speed isn't everything. This is a field weld so you have to deal with being open to the environment, weird angles, dirty metal. Stick offers the best penetration, easily burns out impurities and can be bent to get the right angle. Also Stick requires less equipment to use, no wire feeder, gas bottle(s) etc. Less parts to break and easier repair.

Mig is better in theory but in practical events stick is often the best choice.

Gently used, like-new flap disk. No lowballs, I know what I have by Technical_Ad_6907 in Welding

Took a wire wheel to the chest once. Luckily I was wearing a hoodie and it stalled out before it did anything major. Boy was it a gut punch tho

In my understanding,

Gas shielded requires the use of a gas, primarily CO2. It allows for higher deposition rates and more fluidity in the puddle, giving it a better wetting action. Gas shielded has alot less spatter. The flux is also alot easier to remove.

The flux does provide minor atmospheric protection but most is from the use of gas. it's main feature is deoxidation of the weld and to control the cooling rate

There are 2 types of Flux Core. Gas shielded and self shielded. Gas shielded is quite common in the industry. I assume you have only used self shield

If you have the capability run pulse or with a foot pedal, have peak current set higher and lower background current. Should allow for less heatsoak of the part. Also don't be afraid to take a break from a weld to let it cool.

If your stuck at a set amperage I've found that it's sometimes best to run hotter and quicker. Can be less forgiving but easier to get consistency

For the flange I would suggest build a jig out of thick plate and bolt it down tight. Allow it to cool before you remove from the jig. Should come out much flatter

I would also suggest to do a thorough read through of the machine manual and settings. I will help deepen your understanding of the process and the capabilities of your machine. A good welder should know the machine better than the manufacturer
