3.NA-5- Set the DC-1000 mode switch to the process being used - CV(I) Innershield or CV(S) Sub Arc. Set the DC-1000 machine/remote switch in the remote position. Set the OCV control four volts higher than the welding voltage and the inch speed at 1/2 the welding wire feed speed for the initial test weld. Adjust the OCV and inch speed as required for optimum starting. Refer to the NA-5 instruction manual for data regarding the setup of controls and modes on the NA-5.

4.LN-8- Set the LN-8 mode switch (located on the CC board) to the CV position. Set the DC-1000 mode switch on CV(I) Innershield or CV(S) Sub Arc according to the process being used.

5.LN-7, LN-9 and other constant wire feed units - Set the DC-1000 mode switch on CV(I) Innershield or CV(S) Sub Arc according to the process being used. If using an LN-9, refer to the LN-9 instruction manual for further instructions on its use. If using an LN-7, it will be necessary to use either a K775 Remote Control or operate the DC-1000 with the machine/remote switch in the machine position.
