SHADE CONTROL (fig.10)
4.15.1.
Select the shade DIN 9 to 13 based upon the welding process you will use by consulting the"Shade
Guide Table" based on EN 379. The variable shade control knob is for external adjustment. Grind
mode DIN 4 prevents filter lens from auto-darkening for grinding use.

SENSITIVITY CONTROL (fig.11)
4.16.1.
The sensitivity can be set from MIN to MAX by using the infinitely dial knob. The MIN setting suits excess ambient light or with
another welding machine close by. The MAX setting suits low amperage welding and welding in areas with low light conditions,
especially low amperage argon arc welding. Selections between MIN and MAX are suitable for most of indoor and outdoor welding
operations.
4.17.
DELAY CONTROL (fig.11)
4.17.1.
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 SLOW(0.8s) to MIDDLE(0.5s) to FAST(0.2s), by the DELAY switch.The minimum delay suits spot
or short welds. The maximum delay suits heavy current welding and reduces eye fatigue from the arc. Selections between SLOW-
MIDDLE are suitable for most of indoor and outdoor welding operations.
