*Edit* As opposed to starting a new thread for every question, I'm going to collab them all into one thread; I'll just change the name when something new comes up! To make a long story short, I'm currently doing my "A" level welding course here in British Columbia, and when I have a question about a weld procedure or I'm looking for advice or input on something, I'll post it here. The course consists of 7018 roots on pipe and plate (9018 fill and cap, the college teaches it on mild due to cost restrictions), stainless SMAW and TIG on pipe; later on, at least one pressure test and the BCP-100. :)
Suffice, the question of the title will be in my latest post. :)

(was titled "7018 root problems")
Mainly in the overhead position and stop/starting issues. Right now we're just doing them on plate in all four positions.
Regardless, the plate Specs. 1/8" opening, 1/8" land, 60 degree included angle.

Amperage/Machine specs.
Running 1/8" 7018 at 90 amps DCEN for root only. Rod angle is straight on with a SLIGHT push angle; no weave.
Results.
