Having made this connection, it is permissible to set one transformer at its maximum and the other at its minimum capacity. By this arrangement a very wide range of current flow is available.

It is entirely self-contained, is well built and delivers 40, 50 and 60 amperes to the arc. CAUTION: Before installing see that the voltage rating and cycles on the name plate correspond with that of the current supply.

Any other location will greatly lessen the value of amperage control.
