(1)
As a rule of thumb, start with a shade that is too dark, then go to a lighter shade which gives sufficient view of the weld zone without going
below the minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow light, it is desirable to use a filter lens that absorbs
the yellow or sodium line the visible light of the (spectrum) operation
(2) These values apply where the actual arc is clearly seen. Experience has shown that lighter filters may be used when the arc is hidden by the
workpiece.

FILTER PLATE AND LENS REPLACEMENT
Replacing Front Clear Cover Lens: Replace the front cover lens if it is dam-
aged. Remove ADF holder assembly per Figure 1. Remove front cover lens from
helmet assembly. Carefully remove gasket from cover lens. Install new cover
lens into gasket and assemble to helmet shell. Make sure to assemble cover
lens and gasket into helmet shell the same way as it was removed.
Change the Filter Plate: Remove ADF holder assembly from helmet shell. See
figure 1 for removal. Flex top end of the ADF holder to allow for Retaining Frame
and Filter plate to be removed from ADF assembly. Install new Filter Plate into
ADF holder per figure 2 below. Install Retaining Frame into ADF holder making
sure Retaining Frame Holding tabs are facing towards the Filter Plate. Install
ADF holder assembly into helmet shell.
INSTALLING AN AFTERMARKET MAGNIFYING LENS:
Simply slide the magnifying lens into the short rail located on the sides of the
ADF holder per Figure 3.
