The welders that we use at my school are Lincoln idealarc 250's any idea for how many amps on those machines or just use the same amperage as you described earlier?

Lately I have been practicing vertical up stick on a 3/8 inch Tee-Joint with an 1/8 7018 for an up coming project in the welding class I take at my local tech school. When I was done I noticed alot of the bead was just random blobs here and there. I was doing some research the day before on a websit...
