Another throwback !!

I can't believe it!

First an empty welding gas bottle, then long waiting times for the last ali sheets to be lasercut, additional a lot of work in my enterprise and now problems with the welding machine. Damn'!!

What comes next?!

Yesterday i could bend and weld in the the first channel part (Center foot).

But shortly after that, the welding machine's transport system refused to continue the work. 

 I think i have found the problem. This roll has two small gaps in which the wire is transported.

And if you look closer, there is some fine debris of Ali all around. That comes from the structure of the gaps in the roll. A raw machined surface. Maybe the gaps are worn out? I cleaned the roll, i cleaned the bearing on the other side that is pressing the wire, but until now no success.

Better to order a new roll to get this job done. Meanwhile i will go to the metal Shop where i got the sheets from to ask if they might do the last welding for me.
