I was cutting some 3/4" plate the other day and I was almost done with my cut when I noticed a small flame coming out between the retaining cap and the shield. My nozzle went at the same time. I did do a edge start on the plate. Any Ideas Jim?



Another thing is I can not get this thing to cut very straight holes. I am getting almost .030 taper on a .375 hole in 1/4". My powermax45 would do .015" taper on the same hole. I have tried different cut heights and speeds. I tried 45 and 65 amp nozzels. My 45 was way better at taper on 1/4" and 3/16" but the 65 does very nice on 3/8" and 1/2" I get a good positive bevel with the 65 no matter what height or speed I run.
