SENSITIVITY CONTROL

The sensitivity can be set from LOW to HIGH using the dial knob. 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.

DELAY CONTROL

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 (0.1 sec) to MAX (1.0 sec) using the dial knob. 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 indoor and outdoor welding operations.

SELECT THE GRINDING SETTING

The headshield has a ‘Grinding’ setting on the selector panel. When set to

‘Grind’ the auto darkening function is disabled. The headshield then provides

eye and face protection for sparks and airborne particles created during

grinding activities. DO NOT WELD WITH “GRIND” SELECTED.
