  • Slag...not forming...bad technique?

    I was watching my Wall Mountain video again (for about the 12th time) and the bead that is demonstrated (FCAW) has a nice dome of slag that is chipped away.

    Now, it appears that the welder is using a more powerful unit than my HH140...don't know if this is the difference but my beads don't form this slag covering...maybe it's not supposed to and/or maybe nothing to worry about.

    But if I'm doing something wrong in this area, I'm not sure the weld is correct. Is gun angle an issue or ......?

    I presume that you are using FC also?

          I love E71T-11(I run Lincoln NR-211 5/64), it gives a nice clean bead just like 7018. I just hit it with the wire wheel and it is nice and shiny. I was running it all day today putting a cutting edge on a big Volvo loader, smooth as silk and a nice clean weld.

            Thanks Massey...yeah, I brush mine off...I guess if the weld holds, that's all that matters...just thought I wasn't doing something right.

              Tozzi...I'm using the E71T-11 and that's what is used in the video...I just need more practice.

                Like Tozzi said,the Lincoln NR-211 is good wire.It don't smoke near as much as the other wire. I have been getting it at Home Depot in Lake Worth, cheaper than any other place I've found.

                  Well, that's a nice new store...I'll take a run over there from south Fort Worth and check it out.

                  I think after the inital spool ran-out from my 140, I've been getting a "Weld it" brand from Northern...didn't know the brand would make that much difference but I'll see.

                  thx

                    nr232 would probably give you a better quality weld
                    nr211 not rated for over 1/2"

                      Who do you think makes Weldit? Hint, click the products tab at the top left and look at the fourth choice down...

                        Don't want to get too far OT, but since you brought it up, seems I remember a discussion about the HB28 wire and Weldit wire. With my MM180, I got a 2# spool of HB28, and it looks like the Hobart logo at the bottom of the label is the same as Hobart Welders. So, is the Weldit brand just for storefronts while the HB stuff is for a different market?
