INTERNAL SET UP CONTROLS

Precision TIG 275 models which have an Advanced Panel (K2621-1) option installed* have the following additional control features which are set up using the DIP Switch (S1) provided on the internal panel of this option.

Access to this internal panel is obtained by removing the two screws securing the top corners of the Precision TIG front control panel and swinging the con- trol panel down to reveal the panel mounted on the sur- face of the Precision TIG Control board:

CAUTION

THE CONTROL BOARDS CONTAIN STATIC SEN- SITIVE COMPONENTS

To avoid possible damage to these components

be sure to ground yourself by touching the machineʼs sheet metal while handling or making settings on the internal control box components.
