REMOTE OUTPUT CONTROL OPTIONS

The Multi-Weld 350 is provided with a 6-pin remote receptacle to permit use with the 25 ft.(7.6 m) K857 or

100ft. (30.4 m) K857-1 Remote Output Control options. The remote receptacle can also be used with the LN-25 equipped with the K444-1 Remote Control option. These remotes have single-turn resolution on a Minimum to Maximum numbered dialplate.

CV MODE WIRE WELDING

The Converter in CV mode was designed for use with an arc-powered wire feeder like the LN-25. The Converter output is always “hot” when the mode switch is not OFF. Therefore it is recommended that the LN- 25 model be equipped with the internal contactor in order to have a “cold” electrode when the gun trigger is released.

The CV mode recommended processes are positive

(+)polarity wire welding within the output capacity of the Converter, including:

Flux Cored Arc Welding (FCAW)

Innershield: NS3M (5/64-3/32)

NR305 (.068)

Outershield: OS-70 (1/16-5/64)

OS-71 (.045-1/16)

MC-710 (.045-5/64)

Gas Metal Arc Welding (GMAW)

Carbon Steel: L50/56 (.030-1/16)

CCMODE STICK WELDING AND GOUGING
