i got a question, im using my miller 225 welder and welding 2 3/8 pipe to 3/16th plate using 7018 rod, its ok, but i have the welder set at the arc sign,where i usually weld fence pipe, and its looking strange and i dont think its penetrating the plate much as i dont see a burn circle on the other side, it does seem to weld the pipe fine and will burn through it if i linger with the puddle. although i havent been able to knock the plate off the pipe with a small hammer should the welder be set at + ? or what, im making 18 underground mounts for new park benches that the rich people didnt think to order, and id hate to have it fail and dump some rich old lady on her fanny
