Weldclass Promax 180 Electronic Welding Helmets User Manual
BEFORE YOU START – IMPORTANT INFORMATION
Warning: Incorrect use of this product may cause serious injury.
- All users of this helmet should read & understand this manual before using the product
- Use this helmet only for the intended application as described in this manual
- Each time the helmet is used, it should be checked for correct operation: Use a cigarette lighter or strong light source to check that the lens is activating correctly.
- Stop welding immediately if the helmet filter/lens fails to darken when the arc is struck. Do not continue use until the malfunction has been rectified. Read this manual for further information and if in doubt, return the helmet to your Weldclass distributor for further inspection.
- 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.
- Never use the helmet without the outer & inner cover lenses correctly installed. Failure to do so will damage the Auto-darkening filter & void warranty. Always keep clear cover lenses clean and replace them regularly. Dirty or scratched cover lenses may cause the auto-darkening filter to malfunction.

AUTO-DARKENING FILTER/LENS (ADF) CONTROLS & FEATURES

-
POWER SUPPLY
Promax 180, 200: Solar powered with internal re-chargeable, non-replaceable battery Promax 350, 500: 1 replaceable battery, plus solar assistance via a solar panel on the front of the ADF which absorbs energy from the welding arc. The solar panel supports the battery to extend battery life whilst the helmet is activated, however it will not power the helmet alone. The batteries are not re chargeable – if the batteries are discharged, they must be replaced with new batteries. -
ON / OFF
(Excludes Promax 180) When the switch is in the ‘WELD’ position, the ADF is ready to weld at any time.
IMPORTANT: For maximum battery life, switch the ADF to ‘GRIND’ position when the helmet is not in use. This will turn it off & prevent any nearby light sources from activating the ADF and discharging power. To conserve power, the ADF will automatically switch to ‘sleep mode’ if it does not detect an arc for a period of 10 minutes, and will automatically switch on as soon as an arc is detected. [Promax 350 & 500 only]. -
SENSITIVITY CONTROL
This adjusts the sensitivity of the arc sensors to best suit the welding task & surrounding environment. Low sensitivity helps prevent the ADF reacting 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. -

DELAY ADJUSTMENT
This adjust the time the ADF takes to switch from dark back to light when welding stops. Short delay time is best for tack welding and short welds. A longer delay may be required if welding heavier materials, where the weld pool emits bright light for a brief period. -
WELD/GRIND SWITCH
(Excludes Promax 180) Switching to ‘Grind’ mode will ‘lock’ the ADF into the light shade mode so that it will not activate whilst the operator is grinding.
WARNING: Never use the helmet for welding whilst the ADF is switched to ‘Grind’.
WARNING: Always wear safety spectacles or goggles under the helmet when grinding.
REPLACING ACCESSORIES & MAKING ADJUSTMENTS
-
REPLACING BATTERY [Promax 350 & 500 only] When the batteries have become discharged, the LED light will turn on indicate that the batteries should be replaced immediately. [Refer to diagram under section 5] Unfasten the plastic clip on the bottom of the lens retainer frame (6) & remove the ADF & frame (2+6). Remove the ADF (2) from the frame (6). Slide open the battery cover & replace the battery. As indicated on the battery cover, the battery should be placed with “+” side upwards (closest to the battery cover). Reverse these steps to re-assemble the helmet.
-
REPLACING COVER LENSES
[Refer to parts diagram under section 5] Replacing Outer Cover Lens: Unfasten the plastic clip on the bottom of the lens retainer frame (6) & remove the ADF & frame (2+6). Remove the outer clear lens (1) & replace. Reverse these steps to re-assemble the helmet.
Replacing Inner Cover Lens: Unfasten the clip on the bottom of the lens retainer frame (6) & remove the ADF & frame (2+6). Remove the ADF (2) from the frame (6). Remove the inner cover lens (3). Fit new cover lens & reverse these steps to re-assemble the helmet.
IMPORTANT: Use only original Weldclass cover lenses to ensure correct fit and conformance to safety standards. -
INSTALLING A MAGNIFICATION LENS
Any standard 108x51mm magnification lens can be fitted by insert it into the retaining tabs on the inside of the lens retainer frame (6), in front of the viewing window.
Note: To prevent fogging, place the flat side of the magnification lens towards the ADF (auto-darkening filter/lens). -
HEADGEAR ADJUSTMENT
Tightening Knob (Y): Expands or contracts the main headband. Turn 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 different 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 operators face. Loosen the headgear retaining nut to change position (front, centre or rear). The same position should be selected on both sides.

MAINTENANCE
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.
- Inspect lenses frequently. Immediately replace any scratched, cracked, or pitted lenses as they may impair visibility and reduce protection.
- Inspect Helmet Shell and Harness Assembly frequently. Replace any damaged or worn components immediately.
- 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.
