I have the two berner one. they work good but you would want to buy some hotter fire blanket for it. It comes with 2300 I got some 2700, some Ensen tuff and Itc 100, it works good but is not as fual efishent as most. It takes about 15 psi to get welding heat. A 20lb tank will last about 6-8 hours less if your welding.
