Auto-Darkening Filter Welding Helmet
User’s Manual
WARNING: Read and understand all instruction before
using!
This Auto-Darkening filter Welding Helmet BARRACUDA (S777C
model) is designed to protect the eyes and face from sparks, spatter,
and harmful radiation under normal welding conditions. Auto-
darkening filter automatically changes from a light state to a dark
state when an arc is struck, and it returns to the light state when
welding stops.
Auto-Darkening filter Welding Helmet comes ready for use. The only
thing you need to do before your welding is to adjust the position of
the headband and select the correct shade number for your
application.
BEFORE WELDING
Check the front cover lens to make sure that they are clean, and that
no dirt is covering the four sensors on the front of filter cartridge. Also
check the front/inside cover lens and the front lens retaining frame to
make sure that they are secure.
Inspect all operating parts before use for signs of wear or damage.
Any scratched, cracked, or pitted parts should be replaced
immediately before using again to avoid severe personal injury.
Check for light tightness before each use.
Select the shade number you require at the turn of a shade knob
(Seeing the Shade Guide Table No.1). Finally, be sure that the
shade number is the correct setting for your application.
Adjust headband so that the helmet is seated as low as possible on
the head and close to your face. Adjust helmet's angle when in the
lowered position by turning the adjustable limitation washer.
DARK SHADE NUMBER SELECTION
The shade number can be set manually between 9 - 13. Check the
Shade Guide Table to determine the proper shade number for your
application. Select a shade number by turning the shade knob until
the arrow points to the required setting (See Shade Guide Table
No.1).
PRODUCT FEATURES
This model is designed & equipped with a special turnover (up &
down) headband mechanism. When welder turns over the helmet to
welder’s head top, the headband mechanism makes helmet’s gravity
center to be more lower, and be coincided with the center of
welder’s head. The design of welding helmet greatly lowers the
fatigue of welder’s head (& neck) and make welder feel more
comfortable than before while at working.
At the moment of starting welding, it automatically changes filter
screen from clear to dark in only 1/30,000 sec.
Dark to clear delay adjustment: Operator can vary the time for the
filter to return to clear state.
Outside sensitivity adjustable can make the operators more
convenient while operating.
At the moment of stopping welding, the filter screen automatically
changes from dark to light state according to your per-set delay time.
(Turning the time-setting switch to the "short" position--then, it can
vary at 0.25s ~ 0.35s; Turning the time-setting switch to the "middle"
position--then, it can vary at 0.35s ~ 0.5s; Turning the time-setting
switch
.
to the "long" position -- then, it can vary at 0.5s ~ 0.8s).
“WELDING”/ “GRINDING” can be selective.
The helmet utilizes high performance solar cells as power supply and
has two 3V lithium batteries as power back-up (batteries can be
replaced). No change of battery is required. And the battery life is
raised to a new limit. Under normal welding conditions, users can
expect a battery has a lifetime of more than 6 years.
Variable shade (DIN) from DIN9 (9) to DIN13 (12) is adjusted at the
turn of a shade knob (shade variable).
The product is in full conformity with related DIN, ISO, EN safety
standards and ANSI Z87.1-2003 standards.
The ultra high performance of UV/IR Auto-Darkening filters provide
full protection for the user's eye & face against UV/IR radiation during
the entire welding process, even in the light state. The UV/IR
protection level is up to Shade 16 (DIN) at all times. It makes welders
feel comfortable in welding working.
