im thinking about investing in a cutting torch, had a stihl chop saw before but it was stolen. i have 2 very large pieces of farm equipment in a tough spot i need to cut up and i figured it will pay for itself after 1 of them and used a lot more in the future. any tips on purchasing one, the gas i need? im pretty sure they use oxy-acetelyne but not positive any advice would be great im a rookie when it comes to these things. noticed a lot cheap on craigslist
