Lincoln Electric IM526-B manual Output Terminals Switch, Arc Force / Inductance Control

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 17V, may operate better in the FCAW mode. Voltage in the GMAW mode can become erratic when welding is attempted using voltages equal to or less than 17V DC+.

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 and K432 options or LN-7 which will allow the gun trigger to energize the welding terminals.

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 settings.

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

Recommended Arc Force / Inductance Settings

For Selected Applications

Full Range Is 1-10,

1 Is Very Soft, 10 Is Very Crisp

*1 = Lowest pinch, highest inductance and least spatter.

10 = Highest pinch, lowest inductance and most spatter.
