INTERNAL SET UP CONTROLS

Precision TIG 375 Advanced Panel has 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

machine’s sheet metal while handling or making settings on the internal control box components.

PRECISION TIG ADVANCED PANEL

(Internal Panel)

•Switch #7 Arc Force Level – Prevents "stubbing" of the electrode by providing extra output current if the arc voltage drops below the level required to sustain the welding arc. High (+65%) and Low (+12%) factory set levels are selectable which are good for most stick welding applications.

ON – Higher for a "crisper" arc, often desired for 6010 type electrodes.

OFF – Lower Arc Force (as shipped) for a "softer" arc with 7018 or general type electrodes.

• Switch #8 (NOT CURRENTLY FUNCTIONAL)

TIG WELDING FEATURES

The following DIP switch feature selections function only when the Precision TIG is set to TIG mode (See Item 3):

•Switch #1 Preflow/Postflow Time Extension* (See Item 9)

ON – Doubles the time ranges.

OFF – Standard time ranges (as shipped).

STICK WELDING FEATURES

The following DIP switch feature selections function only when the Precision TIG is set to Stick mode. (See Item 3):

•Switch #6 Hot Start Level – Provides an extra out- put "boost" pulse at the arc strike to enhance arc starting. This is factory set for a level (about 50% extra) which is usually good for most stick welding applications

ON – Hot Start level is used (as shipped). OFF – No Hot Start.

•Switch #4 (NOT CURRENTLY FUNCTIONAL)

•Switch #5 Crater-Fill Level (See Item 7)

ON - Level is minimum rating of the machine (2A) OFF – Level (as shipped) is Minimum Output setting

(same as Start level).
