MODE SWITCH

GTAW Optimized for both scratch start and Hi- Freq kit use.

CCSOFT Best for EXX18 thru EXX28 stick elec- trodes.

CCCrisp Use this mode for stick welding with EXX10 thru EXX14 electrodes. Non- welding applications such as resistive heating or output tests with resistive loads should be done in this mode with Arc Force Control set to minimum.

CV FCAW This setting has been optimized for Innershield® and Outershield® flux-cored electrodes.

CV GMAW Short circuit, glob and spray transfer solid wire and gas welding are done in this mode. Low end procedures, less than 16V, may operate better in the FCAW mode.

ARC FORCE/INDUCTANCE CONTROL

This control functions in all modes except GTAW. For

CCmodes, this control acts as an Arc Force adjust- ment. The arc is soft at the minimum settings and more forceful or driving at the maximum settings. Higher spatter levels may be present at the maximum set- tings.

For CV modes, this control will set the degree of “pinch effect” which predominantly affects short circuit trans- fer. In FCAW, the maximum setting is generally pre- ferred. With GMAW, the upper half of the range is pre- ferred with CO2 or high content CO2 mixed gas. The lower half is for inert gas mixes.

OUTPUT TERMINALS SWITCH

For processes and equipment that require energized machine terminals (stick, TIG, air-carbon arc cutting or hot tip LN-25), set the Output Terminals Switch to “ON” position.

Set to the REMOTE (OFF) position when using LN-25 with K431/K432 or K624-1 options or other wirefeeders which allow the gun trigger to energize the welding ter- minals.
