  1. G. Richardson

    So far it’s a good machine. Cut 22″ diameter 12 gage stainless duct with ease

  2. Cj

    Great little handy plasma cutter, does everything I need it to do. Small enough to carry around but powerful enough to do the job

  3. Mark A. Schwarting

    Very cool little unite. I have never use a plasma cutter before, but have used oxy acetylene for many years. I will never cut metal again with gas. (Providing a have electricity) First cut was 2 inch 1/8 square tube cut like butter. Second cut was 3/16 Ar 500 plate steel. It did have to work but i cut 27 inchs in less then 5 min. Probably was me not really knowing what i was doing. But still quicker and cheaper then oxy acetylene.

    I am VERY HAPPY with how this machine runs! I was worried to buy such a inexpensive machine but the budget is a little tight and I had a job to do. I needed to cut down a full size truck flatbed to fit on a short bed. I bought the unit and set it up. I plugged it in and went to work. It came with extra tips and I preferred to use the longer ones for better visibility of the arc. The items i was cutting was up to 3/8″ plate. It cut great and even cut through doubled up plates in some spots. I used a timer when running the machine because I did not want to burn it up. The metal i was cutting was rusty and dirty but still powered through. I was running it on 220v. The shielding on the torch lead is not very durable and you will need to watch that you don’t send hot sparks at it. It is small light weight but works great. I recommend this for home owners and do it yourself type of people.
