butane/propane welder?

[chopperrr]

I was just asking around about an oxy/acetylene set, and a guy showed me a set that had a mini torch with a bunch of mini precision tips. There was a peace of paper with some info on the tips, and apparently some of them are made for a butane+oxygen setup (or whatever you wan't to call it). The guy told me you can combine the two, and it was written that you get a 2700 degres Celsius flame (while with oxy+acetylene you get about 3200). So,as I already have a butane tank, I was wondering if 2700 degrees is enough to weld and cut steel?

Hi Stevan
I have seen those torches around, and they say you can cut and weld with them, but I never have use one.

This might give you enough info.

I really hope so. It will save me about 100 $ if I don't buy two tanks, but one (for oxygen).

I've got a propane/ oxy set up that I weld cut and braze with. Just need a 2 piece cutting tip for the propane. All the other tips are the same, it's a little slow to heat when cutting and you may have to go up a size on your welding tips but I've had no big complaints.
