Warning: Incorrect use of this product may cause serious injury.
a. All users of this helmet should read & understand this manual before using the
product
b. Use this helmet only for the intended application as described in this manual
c. Each time the helmet is used, it should be checked for correct operation: Use a ciga-
rette lighter or strong light source to check that the lens is activating correctly.
d. Stop welding immediately if the helmet lter/lens fails to darken when the arc
is struck. Do not continue use until the malfunction has been rectied. Read this
manual for further information and if in doubt, return the helmet to your Weldclass
distributor for further inspection.
e. This welding helmet does NOT provide unlimited protection. All appropriate PPE
and safety-wear must be worn, and safe work practices must be followed at all times,
in accordance with applicable industry OH&S regulations. Arc rays can burn eyes and
skin. Fumes and Gases can be hazardous. Noise can damage hearing. Flying particles
can cause impact injury or death.
f. Never use the helmet without the outer & inner cover lenses correctly installed.
Failure to do so will damage the Auto-darkening lter & void warranty.
Always keep clear cover lenses clean and replace them regularly. Dirty or scratched
cover lenses may cause the auto-darkening lter to malfunction.

3 / AUTO-DARKENING FILTER/LENS (ADF) CONTROLS & FEATURES
Note: ADF = Auto-Darkening Filter/Lens
a. FUNCTION BUTTON (FUNC.)
This scroll through Sensitivity, Shade and Delay settings. Press the Up and Down
buttons to adjust the Function that is ashing. Once adjusted, wait for the setting to
stop ashing to store the new value.
b. SENSITIVITY CONTROL (SENSI)
This adjusts the sensitivity of the arc sensors to best suit the welding task &
surrounding environment. Low sensitivity helps prevent the ADF from reacting
to other nearby light sources. High sensitivity may be required if welding on low
current &/or when TIG welding. Low to mid sensitivity is recommended for most
welding applications.
c. MODE BUTTON
This changes between WELD 9-13, WELD 4-8, CUT, and GRIND modes.
Also, press and hold this button to test/check ADF is operating correctly.
Grind Mode locks the ADF to “o”(Shade 3). If helmet has eternal grind button,
holding this for 3 sec will also turn grind mode on or o.
Cut Mode locks the ADF to the set shade level.

f. TIME DELAY ADJUSTMENTS (DELAY)
This adjusts the time the ADF switches from dark back to light when welding stops.
A short delay time is best for tack welding and short welds. A longer delay may be
required if welding heavier materials, where the welding pool emits bright light for a
brief period.
g. GRADIENT DELAY
Activate this by pressing the FUNC. Button for 2 seconds.
When this is active the shade will decrease from your preset shade setting to shade
3. This is best used for welding heavier materials so you can monitor the weld as it
cools.
h. MEMORY SAVE
.1 - You can save up to 10 of your favourite settings.
.2 – M/R = Memory Recall, this will display when you are trying to Recall a saved
Memory setting. M/W = Memory Write, this will display when you are Saving a
Memory Setting. The Number represents the Memory number slot you are saving to
or recalling. Use the Up and Down buttons to scroll through the memory Slots. Wait
for 5 seconds after selecting the desired memory slot to save or recall these settings.

REPLACING BATTERIES
When the batteries have become discharged. You can view the battery level status on
the Digital Display (h).
Remove the Front cover lens before removing the ADF. For the Promax 650 also remove
the Grind Switch by unscrewing the button retainer ring and pushing the button into
the inside of the helmet.
Remove the ADF by pressing down
on the 2 tabs (i) at the top of the ADF
while simultaneously pressing the ADF
forwards out of the front of the helmet.
Remove the screws holding the battery
holders in place and remove the holders.
Reverse these steps to re-assemble
the helmet once new batteries are installed.
REPLACING COVER LENSES
Replacing Front Cover Lens: Firmly pull 1
side of the Cover lens forwards. Once 1 side
is released the other side will come free.
Replacing Inner Cover Lens: Using the
access point at the top of the ADF, pull the
lens backwards so the lens bends and the
corners release from their holders.
NOTE: If you have the mag lens holders
installed, you may need to remove the
whole cassette rst. (see instructions in a
Replacing Batteries)
IMPORTANT: Use only original Weldclass
cover lenses to ensure correct t and
conformance to safety standards.

4 / REPLACING ACCESSORIES & MAKING ADJUSTMENTS – Cont’d
HEADGEAR ADJUSTMENT
Tightening Knob (Y): Expands or contracts the
main headband. Turn the knob clockwise to
tighten, and anti-clockwise to loosen.
Top Strap (W): Adjust the strap buckle
according to personal preference & head size.
Tilt Angle (X): The locating pin on the right
side of the helmet can be moved to dierent
positions to adjust the tilt angle of the helmet
when it is resting in the lowered position.
Horizontal Position (Z): Adjusts the distance of
the helmet from the operator’s face. Loosen
the headgear retaining nut to change position
(front, centre or rear). The same position
should be selected on both sides.
INSTALLING A MAGNIFICATION LENS
Install the 2 Magnication Lens holder clips
(supplied as separate parts with helmet) to
the mounting positions on either side of
the viewing window. These will click rmly
into place.
Any standard 108x51mm magnication lens can
be tted by inserting it into the retaining tabs on
the inside of the lens retainer frame (j), in front of
the viewing window.
Note: To prevent fogging, place the at side of
the magnication lens towards the ADF (auto-
darkening lter/lens).

6 / MAINTENANCE
7 / TROUBLESHOOTING
The helmet and ADF must be checked regularly. Defective equipment should not
be used. Parts that are broken, missing, worn, distorted or contaminated, should be
replaced immediately.
a. Inspect lenses frequently. Immediately replace any scratched, cracked, or pitted
lenses as they may impair visibility and reduce protection.
b. Inspect Helmet Shell and Harness Assembly frequently. Replace any damaged or
worn components immediately.
c. Keep the Sensors and the Solar Panel clean at all times. When cleaning the Welding
Helmet or Filter Lens do not use solvents or abrasive cleaning agents. Clean with a
soft cloth after use.
FAULT POSSIBLE CAUSES POSSIBLE REMEDY
The Filter Lens does not
activate at all (fails to darken)
Batteries are discharged Replace Batteries
Batteries are not tted correctly Check batteries (see section 4)
Battery or terminals are dirty Inspect & clean battery/terminals
The Filter Lens ickers or
intermittently fails to darken
Front Cover Lens is dirty or
scratched & is obstructing the
sensors
Replace cover lens
Sensors are dirty Clean the Sensors with a soft cloth
Sensitivity too low Increase sensitivity level
Momentary disruption to sensing
of the arc
Increase delay time adjustment (will
help compensate for
momentary disruptions)
Filter lens is dark when no arc
is present or stays dark after
the weld is extinguished
The ambient light level is too bright Reduce the ambient light level in
the area
Sensitivity too high Reduce sensitivity level
