+1 on the Trailblazer 302.
Had a Bobcat 250 for a few years now. Big improvement from the 225s I ran for years. Way more stable arc and more grunt for the bigger stuff. Most work is done with 7018 × 1/8" or 3/32" for the thinner stuff. Mostly structural steel. Mostly vertical or overhead position. Seems odd to do a flat pass on the odd chance I get one.
Always used a 10018 for the harder surfaces. Little higher tensile strength, but not what you need to fix a bar rail.
Less is definitely more there. Pay close attention to what others who are much more knowledgeable say about preheat and slow cool down.
That is the key to it being strong, not cracking, and being easier to dress.
Definitely would recommend a backer of some sort of dissimilar metal in the groove. It Will be difficult to dress if you don't.
