VII. DARK SHADER SELECTION
•
Select the shade level according to the welding process and the value
of the welding current by turning the potentiometer knob for the shade
selector.
•
The shade number can be between DIN9 to DIN13. Select a shade
number by turning the shade knob until the arrow points to the required
setting (See Shade Guide Table)
•
ALWAYS use suggested shade numbers instead of minimum shades.
•
Provide additional task lighting that suits welders' needs.
•
ALWAYS use the same shade as the welder's if you are directly
observing the welding arc.

*As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives sufficient
view of the weld zone without going below the minimum.
