COMMON PROBLEMS AND REMEDIES

Auto-Darkening lter does not darken or ickers

• Front cover lens is soiled or damaged (Change the cover lens).

• Sensors are soiled (Clean the sensors surface).

• Welding current is too low (Adjust the sensitivity to a higher

level).

Slow response

• Operating temperature is too low (Do not use at temperatures

below -10º C or 14º F).

Poor vision

• Front/inside cover lens and/or the lter is soiled (Change cover

lenses).

• There is insucient ambient light.

• Welding shade number is incorrectly set (Reset the welding

shade number).

SELECTING SHADE LEVEL

Select the shade level you require according

to the welding process you will use. Refer to

the “Shade Guide Table” below for necessary

settings. Turn the shade control knob on the

lter to the shade number required.

SELECTING DELAY TIME

When welding ceases, the viewing window

automatically changes from dark back to

light but with a pre-set delay to compensate

for any bright afterglow on the workplace.

The delay time/response can be set to

“S” (short: 0.1 sec.) or “L” (long: 1.0 sec.). Set

as required using the variable dial knob

on the back of the shade cartridge. It is

recommended to use a shorter delay with

spot welding applications and a longer delay

with applications using higher currents.

Longer delays can also be used for low

current TIG welding in order to avoid the

lter opening when the light path to the

sensors is temporarily obstructed by a hand,

torch, etc.
