Hi, well i think you will find most of the welders that have the moving core
system either the amperage handle is sticking out front and moves verticle,
or is a wheel on the top of the welder. Monkey wards welder has the lever
out front and is the moving core type. once worn it will move to the low
current position all by its self! cul brian f.
