I'm looking to finish a project of mine, a 20 ton Shop press, bottle jack H-frame variety. I need to weld the upper cross braces to the upright beams. I've angle (45 deg.) the pieces where they will be welded together.
I have a HarbourFreight 140 stick welder, the docs say it can do 140A but the welder is only marked at 110A, go figure.
I cranked it up as much as I could and ran some practice beads of 70183/32, it produced a nice looking weld, at least for my abilities.
I'm looking for answers on which rod should I be using for this application. Currently, I have 6011-3/32, and the 7018-3/32.
Should I be more concerned with the penetration depth or the strength of the weld, 60 or 70 psi(?) rating of the rods. I've read that the 6011 is a deeper penetrating rod then the 7018, but the 7018 is a stronger weld.
Any comments, suggestions?
