hello all,i have a 3 phase sabre arc 40i plasma here which was working fine cutting light material, i went to cut some 10mm plate and it stopped cutting after about 3 inches in. the machine had the red overload light on i turned it off and turned it back on the red light stayed off until i tried to cut again the air come on but a couple of seconds after so did the overload light i changed the tip but still no start this happened a week ago and i have tried it a number of times since. would anyone know where the over load temp sensor is located on theses machines. or any other ideas would be very welcome thanks
