Lincoln Electric IM708 manual Hidden Middle Control Panel Process Set Up Panel, Thermal

B-2 OPERATION B-2

5. THERMAL

•This status light indicates when the power source has been driven into thermal overload. If the output terminals were "ON", the "ON" light will blink indicat- ing that the output will be turned back on once the unit cools down to an acceptable temperature level. If the unit was operating in the "REMOTE" mode, the trigger will need to be opened before or after the thermal has cleared and closed after the machine has cooled down to an acceptable temperature to establish output.

6. CONTROL-REMOTE , LOCAL

•Two status lights indicate the location of output con- trol as pre-determined by the power sources auto- configure system.

•The LOCAL display will be lit when control is at the power source.

•The REMOTE display will be lit when a remote pot/control is detected.

These Output Control configurations can be overrid- den (switched) with the CONTROL push button. When changed, the unit will power up in the configura- tion it was in when it was last powered down.

Hidden Middle Control Panel – Process Set Up Panel

The middle control panel is removable to allow for upgrades (see Field Installed Options/Accessories). Additionally, this panel is hidden by an access door to reduce appeared complexity and provide protection to the controls.

7. WELD MODE SELECT

The Mode Control button selects the following welding modes desired.

CC-STICK SOFT: The Stick Soft process features continuous control ranging from 5 to 425 amps. This mode was intended for most SMAW applications, and Arc Gouging.

•Arc Gouging: Setting the output of the Stick Soft mode to 425 amps will enable the arc-gouging mode. The actual output current will depend on the size of carbon used. The recommended maximum size carbon is 5/16".

•The Hot Start control regulates the starting current at arc initiation. Hot Start can be adjusted from min- imum (0), with no additional current added at arc start, to maximum (10), with double the preset cur- rent or 425 amps (max of machine) added for the first second after arc initiation.

•The Arc Control regulates the Arc Force to adjust the short circuit current. The minimum setting (-10) will produce a "soft" arc and will produce minimal spatter. The maximum setting (+10) will produce a "crisp" arc and will minimize electrode sticking.

CC-STICK CRISP: The Stick Crisp mode features continuous control from 5 to 425 amps. This mode was intended primarily for pipe welding applications.

•The Hot Start control regulates the starting current at arc initiation. Hot Start can adjust starting current up or down by 25% of the preset value. The recom- mended setting for Hot Start is 5 where the initial current is equal to the preset current.
