Hi everybody,
This is my first actual post but I have been frequenting this site for years just lurking. I am welding some 1-1/2 sch 40 black pipe and am having a terrible time with the 7018 cap. I know there is a better way of doing it but this is it. I don't have any problems with the root and could weld it out with the 3/32 6010 no problem but when the 3/32 7018 comes out it just gets down right ugly. I could see rolling it out maybe but this is in position 5g, 6g and some 2g. I have been trying to run around 80-85 but it is just too much heat, super convex stringer, falling out around 3:30 and just flat out unacceptable. I have tried running towards the bottom of the 3/32 7018 weldable range which for excalibur is 70 amps dcep, but even than it is too hot and hard to handle. I think I should be using a smaller 7018 but I haven't really seen anything smaller than 3/32 for 7018. Any help would be awesome.
