I have a plasma cutter not really portable as need 220 and air supply its about the size of a small wire feed welder. pretty slick when needed. use it to cut 1/4 inch aluminum when i bought it.Does anyone have one of those portable plasma cutters ? I bought one last fall and still haven't rigged it up yet but watched some YouTube and I was impressed. Another question , what do you guys pay for Oxy Acetylene tank lease and fill ? I cancelled my lease when I retired because it seemed spendy but I sure miss it.
