[QUOTE="patooyee, post: 430430, member: 483"] I swung by the shop tonight on my way home just to give roll cage tubing a try with the little machine. This was 1.5 x .120 HREW with 3/32 filler, 1/16 thoriated, 100 amps, #5 cup with gas lens. [IMG]https://lh6.googleusercontent.com/-_v0WpXxF2-0/VB-APxj0bnI/AAAAAAAARCQ/jDIszd4iuVQ/w579-h865-no/IMG_20140921_204928786_HDR.jpg[/IMG] It was a bit too hot but the 3/32 filler rod was already sticking a little bit and when I went down to 80 amps it felt about right but then the rod was sticking really bad. I feel like I would have done a lot better with 1/16 filler dabbing more often but I don't have any at the moment. For the most part though I was pretty happy and everything was going good until the tip of the cup shot off with a loud pop. [IMG]https://lh3.googleusercontent.com/-9Qb5CQaRFt4/VB-AYx5FdkI/AAAAAAAARCY/3rpdtNaFBjQ/w1598-h667-no/IMG_20140921_204949474.jpg[/IMG] I'm guessing it just got too hot / was too small? I think a #6 cup would have done better anyway but what causes that to happen? That was my only cup for that torch too so I guess I'm going shopping tomorrow. [/QUOTE]
