??? for gas torch guys

[Timleech]

Get yourself a sheet metal (stepped) nozzle for that sort of thickness.

Well, I finally went out and got a gas rig. I've been wanting one for a while, but putting it off. Finally had to cut something I couldn't cut any other way.

My first try, and I know I need a class, but...

I was cutting 11 ga steel, and it started out real nice for about the first half inch or so, then I got this melted blob, and it just went bad from there.

Any comments on how to recover from that/ how to avoid the blob in the first place?

turn the gas up a little hotter, lean the torch into the work like it was a chisel, hit the O2 and move fast.

dont go slow.

You are using the cutting torch and tip?

[bob308]

for 11ga. you should be using a 00 tip and keep it clean.

neonman, I cut miles of this stuff for sawmill chuting etc. Set up your torch with the recommended tip size for the material.
Line up a preheater (one of the little outside holes) so it will be directly inline with the cut line. Then tighten the tip into the torch head.
Set the gas at 5 and 25 (I cut everything under an inch with this setting).
Fire up the torch and like Mike says...tilt the torch head about 20 degrees back and drag it towards you.
You are best off to use a straight edge so you can concentrate on keeping the preheaters about 1/16" off the metal. The rearmost preheaters will be a bit too close but they do little when tilting the torch head back anyway.

Yep, the thinner the material the harder it is to stay ahead. Pick up the speed and don't dilly-dally.

Thanks for the tips guys, I think I had the
gas regs set too low.

Since we're on the subject of gas cutting and welding will someone answer a question for me? I've seen propane used in place of acetylene for the fuel. Is there a problem or advantage with this? What about pressure settings?
