This morning, I was trying to get a piece of 1.5" mild steel dialed in by cutting thin, 1/2" strips. Our machine can cut 1.5" material with a 150A head on an edge start. I finally found a setting that was cutting beautifully (more info below), and I proceeded to cut an entire strip (4 feet long) with the new settings so I had a clean edge
Much to my surprise, the torch head started glowing, then melting, so I turned everything off. The plasma burned a large gap in the consumable stack (see photo). I not entirely too sure what could have caused this catastrophic failure, but I was wondering if anyone could offer any suggestions. It would be great to not have this happen again!
Settings are as follows:
150A Head
O2 Plasma, Air Shield
Preflow - 80 psi
Plasma Ball - 62
Plasma (psi)- 120 psi
Shield Ball - 62
Plasma (psi) - 120 psi
Arc Voltage - 175
Cut Height - 0.160"
Travel Speed - 8 ipm
I have already purchased a 200A set of consumables that should here before the end of the week that will hopefully run a bit easier.
