Auto-Darkening Filter
Welding Helmet
User’s Manual
MK6000
Warning: For your own safety, please read these instructions carefully before
using auto-darkening welding helmet!
The MK6000 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 MK6000 Auto-darkening welding helmet comes ready for 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 is covering
the two sensors in front of the filter cartridge. Also please check the inside cover
lens and the front cover retaining frame to make sure that they are 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 possible 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
the headband so that the helmet is seated as low as possible on the head and
close to your face. The angle of the helmet is adjusted upon the buckles,
fastened to different bumps.
DARK SHADE NUMBER SELECTION
The shade number can be set manually between DIN9-DIN13. Also if you need
for grinding, you can set the shade number to “GRIND”. Check the shade guide
table to determine the proper shade number for your application. Select a shade
number by the shade knob(Seeing the Shade Guide Table No.1).The shade
goes darker from 9 to 13 gradually by turning knob K1.
PRODUCT FEATURES
The MK6000 is designed & equipped with a special turn over(up & down)
headband mechanism. When the welder turns over the helmet to the welder’s
head top ,the headband mechanism makes the helmet’s gravity center to be
lower, to be coincided with the center of 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 1/10,000 sec.
The delay time from dark to clear is set between 0.1 s and 0.9 s adjustable by
delay knob.
Before welding, the user can press the “TEST” knob to darken the filter and
confirm it is functioning correctly.
The MK6000 utilizes high performance solar cells as power supply and 2
built-in 3V lithium batteries as power back-up. The power will switch off
automatically within 10-15mins after use. Under normal welding conditions,
the user can expect a battery lifetime of more than 3000 working hours. Once
the “Low Batt” lamp flashes, these back-up batteries must be
replaced. Open the battery compartment by pulling the battery tray out.
Replace the old battery cells with the new ones. The positive end (+) of the
battery must face up. Insert the battery tray back to the cartridge.
The MK6000 filter 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 always up
to Shade 16(DIN) making welders feel comfortable during welding.
