WHAM10/WHAM30 Series Auto-Darkening Welding Helmet User Manual
MIN (0.1 second): Shorter delay is for spot
welding applications.
Selecting Sensitivity : The SENSITIVITY dial
(Fig 4. left) will vary the sensitivity from High
("HI") to Low ("LO").
Always set sensitivity at High when beginning
the welding process, and then gradually
reduce it until the filter reacts only to the
welding arc and not any ambient light
(e.g. Sun, artificial lighting, neighbouring
welder's arcs, etc.).
"HI" (High): Mostly for low current welding.
"LO" (Low): When surrounding light sources
create unwanted triggering of the filter.
Power: The welding helmet is powered by solar
energy, however it uses batteries to initiate
when necessary. Replace batteries when LOW
BATTERY light starts blinking. To replace the
batteries, remove the filter from it's holder
(Fig 4.) and slide the battery cover up (Fig 4).
COMMON PROBLEMS AND REMEDIES
Irregular darkening/dimming
Headgear has been set unevenly and there
is an uneven distance from the eyes to the
filter lens. (Reset the headband to reduce the
distance to the filter).
The filter does not darken or flickers
• Front cover lens is soiled or damaged
(Change the cover lens)
• Sensors or Solar Panel are soiled/blocked
(Clean all surfaces. Ensure no surrounding
obstacles are blocking the sensors or solar
panel (e.g. your clothing, etc.)
• Sensitivity is set too low, or delay time is set
too short (Adjust to required level);
• Make sure proper shade is selected, and
filter is not in Grind mode.
The filter darkens without arc being struck
• Sensitivity set too high (Adjust Sensitivity to
a required level).
The Filter Remains Dark After Completing a Weld
• Delay time set too long (Adjust Delay time
to a required level).
Slow Response
• Operating temperature is too low
(Do not use at temperatures below -10º C
or 14º F).
Welding Helmet Slips
• Headgear is not properly adjusted.
(Readjust the headband).
