Welding rod question

The flux, which affects how you weld with it (the welding position, AC vs. DC, spatter, slag texture, etc.).

Wrong! That is rod meant to be welded using only your LEFT HAND!!!

:-)

GWE

The "1" designates an all position rod, as opposed to a "2" for flat position only .

The 8 designates the flux type. In this case, a Low Hydrogen flux.

Ernie: Doesn't it mean flux containing iron powder? Is a 7028 a low hydrogen rod? Or is that a 4 ending that means heavy iron powder, like a

7024?

*********** I was taught the '1' means 'any position' welding. Flat, vertical, overhead. If I remember correctly, I believe the '8' means DC only, reverse polarity.... but I don't remember that well anymore.

From Lincoln's web site:

One of their pdf files, you'll have to find it yourself. I renamed it and don't feel like searching for it right now :)

They do have a lot of good info on electrodes if you care to find it.

Use a fixed font so this lines up correctly.
