Reconnect Procedure

A-3

INSTALLATION

A-3

Multiple voltage machines are shipped connected to the highest input voltage listed on the machine’s rating plate. Before installing the machine, check that the Reconnect Panel in the Input Box Assembly is con- nected for the proper voltage.

CAUTION

Failure to follow these instructions can cause immediate failure of components within the machine.

When powering welder from a generator be sure to turn off welder first, before generator is shut down, in order to prevent damage to the welder.

To reconnect a multiple voltage machine to a different voltage, remove input power and change the position of the reconnect board on the Reconnect Panel. Follow The Input Connection Diagram located on the inside of Case Back Input Access Door. These con- nection diagrams for the following codes are listed below.

1.For Single and Dual Voltage except 380/500 see Figure 1, (S17172).

2.For 220/380/460, see Figure 2, (M14358).

3.For 380/500, see Figure 3, (S17344).

4.For Voltages not listed, see the Input Connection Diagram pasted on the inside of the Case Back Input Access Door.
