Ok first off I'm new to using a cutting torch. Back in the summer I finally got a nice set of Victor torches. Just by doing some practicing and a lot of reading I was pretty pleased with how it was cutting. Nice and clean. I actually shocked myself. Today I was working on a project and was cutting 1/4 inch plate of steel. I was cutting along just fine but occasionally it would stop cutting. I'd release the trigger and squeeze it again and all would be good for a while then it would do it again. Any idea what could cause this? The last time I used it it did it a couple times but not as bad as today, I'm running around 3 pounds on the acetylene and about 10 on the oxygen. It worked flawlessly before with this setting. Any higher the cut was real wide and rough and would fuse its self back together behind the flame as I went along.
