SHADE VALUE
4.4.1.
The shade value ranges are divided into two sections ( 5-8 or 9-13). The shade range can be set to either 5 - 8 or 9 - 13 using the
selector switch (fig.2.1).
4.4.2.
The shade value can be set using the control dial (fig.2.2). Check the shade guide table (above) to determine the proper shade
number for your application. The shade goes darker from 5 to 8 or from 9 to13.

SENSITIVITY CONTROL

4.5.1.
The sensitivity can be set from LOW to HIGH by using the sensitivity contgrol dial (fig.2.5). The LOW setting suits excess ambient light
or with another welding machine close by. The HIGH setting suits low amperage welding and welding in areas with low light conditions,
especially low amperage argon arc welding. Selections between LOW and HIGH are suitable for most of indoor and outdoor welding
operations.
4.6.

DELAY CONTROL

4.6.1.
When welding ceases, the viewing window automatically changes from dark back to light but with a pre-set delay to compensate.
The delay time can be set from MIN (0.2 sec) to MAX (1.0 sec), by shade delay control (fig.2.4). The minimum delay suits spot or short
welds. The maximum delay suits heavy current welding and reduces eye fatigue from the arc. Selections between MIN and MAX are
suitable for most of indoor and outdoor welding operations.
4.7.
GRINDING
4.7.1.
To select between grinding and welding, set the Grind/Weld select switch (fig.2.3) to "GRIND".
NOTE: It is important to return this switch to the WELD position when the grinding operation is completed.
