Just wondering if this is the same wire as the Hobart Excel Arc 71? I tried searching the net for information on it and came up empty. There was 2 boxes of it sitting in the fridge for a long time. The welder that re-tired got it in and didn't like it. I gave him a call and ask him about it and he told me that it was an inner-shield wire and that it had to be run DCEN. I didn't want to argue, but the only thing that I could find on the net was the Hobart Excel Arc 71 that is a dual shield wire. I tried the wire DCEN with no shielding gas as I was told by my re-tired welder and things didn't go very well. Then I tried it with C25 mix and DCEP and it was a little better. I figured that the wire was exposed to the elements for to long and opened up the other sealed box and gave it a try with the C25 DCEP and man what a dream to run. I have not run any of the dual-shield before but this stuff runs like butter and is allot easier to run vertical then the solid wire and inner-shield that I am used to. To make a long story short I would like to get some more of this or something similar for in the shop welding but cannot find any information on it. Any information would be greatly appreciated

Reply:excel Arc 71 is hobart wire. Was it Corex?
Reply:Lars, No it's marked on the spool and was marked on the box Airco Excel Arc 71 Easy Arc 3.I don't know how old the wire is, it's been sitting for a long time. It's no wonder my re-tired welder didn't like it trying to run it as a self shielding wire and on DCEN just didn't work so well. He was one of those guys that pretty much liked to stick weld everything and when the results of this wire was not what he was looking for it was an easier way out to go back to stick welding then to try and figure it out.Like I mentionedf earlier, the first roll that was opened must have been exposed for to long, not sure, but it had porosity problems but the sealed roll runs like butter and the slag pretty much removes itself. |
