here's my tip for you in all seriousness.
buy the little calculator cards. I still have them in the drawer with all my consumables and pull them out often. Miller has them for all processes. I don't have room in my 46 year old brain to remember all the different amperage and filler specs for all different metals, so it's nice to have a handy cheat sheet all the time.
Second tip. don't get lazy. clean everything. before, during and after. including your equipment.
a near-death experience is just god following "catch and release" regulations...
