There were reservations about the $200 plasma cutter. But he picked it up easily and threw it across his steps. Started with thin tubes and worked up to a 1/2 inch slab. All powered by a 9000 watt generator and a pancake air compressor that I use on a trailer as a portable work tool around my farm. The book says the cutter requires 6cfm to run, but I've used both the cutter and compressor for as long as I wanted, at 2.6cfm. I've been wanting to buy a larger compressor and burner kit for my van but don't need it now. With this set of small welder, welding machine and my grinders and this gem, I can cut and weld my tubular fences effortlessly. Money saved on torch gas to pay for a plasma torch. Great offer!
