Ok I was planning on doing
paid work today, but in order to do that I need 3ph 480V, so I return to my monster RPC project. It's only half done-up, sitting on a cart, haphazardly wired and pretty much an embarrassment. Sooner or later the customer will be here to witness the panel I'm building, and I don't want this questionably dangerous eyesore to be an example of my work. so instead of getting comfortable using the RPC in this state, I'm going to go ahead and build a skid for it with forklift/pallet jack pockets, and wire it up properly.
This will be a fair amount of stick welding, and I'm using mostly scrap metal which is painted, rusted, and everything else. I have 7018 and 6011. I should use the 7018, right? Mostly this will be 1/4" and 1/8" steel. What amp settings do you recommend? Do I need to grind off paint/rust? I heard stick just burns through it, so much less prep is required; does that mean
no prep is required?
