i am using a 1989 miller dialarc hf
Been practicing on flat steel plate 1/2”
I am having a problem running stringers on a 45 degree on 1/2” thick 3 by 3 angle iron
What is the key to getting straight tight stringers?
With 7018 on flat plate, what is key to getting the slag to peel off on its own?
Thank you very much
 
Lol. Might have.
5/32” 7018 is a big rod to run. Lots of molten slag while welding and plenty of metal too.
Unless you have to use 5/32” I think you’d be much better off buying 5 pounds of Lincoln
7018 in 3/32” size. It’s the size most often used on pipe welding jobs. Much easier to control. 6” schedule 120 is where I would typically start using 1/8” 7018.
1/8” 7018 on 3/8” thick (or thicker)plate. Otherwise, 3/32” will do anything you’d want with a lot more control of your bead width etc. it’s just easier to run and you’d be in the 80 amp range. Give or take.
Can you post some pictures?
