Reply:Are you worried about the plate warping?
Reply:If you have a d c stick machine , try 7018 3/32 and  after  you got it tacked , then back step it . should work fine .[SIZE="5"Yardbird"

Reply:weld the plate (thicker) to the tube (thin)start on the thicker and work puddle to the thinner
Reply:Watch the puddle! Watch the puddle!
Reply:It will also be a lot easier to have the plate on the bottom if you can...  3/32" 7018 will work nice.Me!
Reply:Thicker to thinner. Okay.The plate is vertical. And I'll be up a ladder. Oh well.

Reply:Watch your arc length.  Keep the arc short, about 3/32" with 3/32 electrode.  Too long an arc will raise the heat and increase your chances of burning through.
