Warning: For your own safety, please read these instructions carefully
before using auto-darkening welding helmet!
The MK8000 Auto-darkening welding helmet is designed to protect the
eyes and faces from sparks, spatter, and harmful radiation under normal
welding conditions. The Auto-darkening filter automatically changes from
light to dark state when the arc is struck and returns to the light state when
welding stops.
The MK8000 Auto-darkening welding helmet comes ready to use. The only
thing you need to do before 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 it is clean and no dirt covering
the four sensors on the front of filter cartridge. Also please check the inside
cover lens to make sure it is secure.
Check all operating parts before use to see if there are signs of wear or
damage. Any scratched, cracked or pitted parts should be replaced
immediately before using again to avoid personal injury.
Check for light tightness before each use.
Select a shade number by the shade knob (Check the Shade Guide Table
No.1). Be sure that the shade number is the correct for your welding
application. Adjust headband so that the helmet is seated as low as
possible on the head and close to your face. The angle of helmet is
adjusted upon the buckles, fastened to different bumps.
DARK SHADE NUMBER SELECTION
The welding shades are available in two ranges, shades 5-8 and 9-13.
The shade section can be chosen by the switch K4. Also if you need for
grinding, you can set the Grind/Weld select （K5）switch to “GRIND”.
Check the shade guide table to determine the proper shade for your
welding application. Select a shade number by the shade knob(Seeing the
Shade Guide Table No.1).The shade goes darker from 5 to 8 or from 9 to
13 gradually by turning knob K2.

PRODUCT FEATURES
The MK8000 is designed & equipped with a special turn over (up & down)
headband mechanism. When the welder turns over the helmet to welder’s
head top, the headband mechanism makes the helmet’s gravity center to
be lower, to be coincided with the center of the welder’s head. The design
of the welding helmet greatly reduces the fatigue of the welder’s head (&
neck) leading to a greater overall comfort when welding.
Upon striking the welding arc, the filter automatically changes from clear to
dark in only 1/25,000 sec.
The delay time from dark to clear is set between 0.2s and 1s adjustable by
the delay knob.
The helmet utilizes high performance solar cells as power supply and 2
built-in 3V lithium batteries as power back-up. The power will be off
automatically within 10-15mins after use. Under normal welding conditions,
users can expect a battery has a lifetime of more than 1 years. Once the
battery power is off, operators can use the lithium batteries of same sizes
for replacement.
The product is in full conformity with related DIN, ISO, EN safety standards
and ANSI Z87.1-2010 standards.
The ultra-high performance of UV/IR auto-darkening filters provide full
protection for the user’s eyes & 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, making welders feel comfortable during
welding.
