Find the Correct Welding Helmet Spare

Different helmet components perform different functions.

Outer cover lenses: Protect the specified optical assembly from surface contamination & wear.

Inner cover lenses: Form part of the approved internal lens arrangement.

Auto-darkening filters: Provide the required welding shade function in compatible helmets.

Grinding visor lenses: Allow clear viewing during approved grinding operations.

Retainer frames: Secure specified lens components in position.

Sweatbands: Support comfort within compatible headgear.

PAPR components: Form part of an approved powered respiratory protection system.

These components are not interchangeable simply because they look similar.

PROMAX 850R Replacement Outer Lenses

The Weldclass WC-06707 is listed as a clear outer lens for the PROMAX 850R.

Its specified dimensions are 220 × 135mm, with five lenses per pack.

A replacement may be appropriate when the existing cover plate becomes scratched or otherwise unsuitable.

Before fitting it, inspect the surrounding helmet components.

Check the filter assembly, mounting points, headgear & any relevant respiratory equipment according to the manufacturer's instructions.

A new cover lens does not make a damaged helmet serviceable.

PROMAX 500 Cover Lenses

The WC-05324 is listed as a clear outer lens for the PROMAX 500.

It measures 137 × 117mm & is supplied in a pack of ten.

This differs substantially from the PROMAX 850R replacement.

For workshops operating several helmet models, separate storage locations can help prevent incorrect parts being fitted.

Label replacement packs with the helmet model plus product code.

PROMAX 600, 650, 680 & 680R Lenses

Selected compatible helmets within these series use a listed 178 × 130mm outer cover lens.

However, shared dimensions do not establish universal compatibility.

The mounting arrangement, manufacturer part number & complete helmet configuration must still match.

Always check the exact replacement listing.

Avoid cutting, modifying or forcing a lens into an unsuitable frame.

Inner Cover Lenses

An inner lens is different from an outer protective plate.

The collection includes P7-CL10546/5, a 105 × 46mm inner lens pack listed for a specified Cigweld Weldskill helmet reference.

This demonstrates why buyers should identify the manufacturer plus model before ordering.

A product described simply as a welding helmet lens may be unsuitable for the intended position.

Check whether the replacement is an inner cover, outer cover or optical filter.

Auto-Darkening Filters Explained

An auto-darkening filter, or ADF, performs a safety-critical optical function.

It is not the same as a clear protective cover.

The PROMAX 100 WC-04094 is listed as a fixed shade 11 auto-darkening lens measuring 108 × 51mm.

It is intended for specified compatible flip-front welding helmets.

The range also includes a PROMAX 200 ADF cassette for suitable PROMAX 180/200 models.

Confirm the approved filter configuration before use.

For related precision-welding equipment, explore TIG Welders.

When Should an ADF Be Replaced?

A filter that fails its required checks must not be used for welding.

Warning signs may include inconsistent darkening, physical damage or abnormal optical behaviour.

Follow the manufacturer's inspection procedure before every use.

If the filter is defective, remove the helmet from service until the issue is properly resolved.

Do not attempt to compensate for a malfunctioning ADF by adding an unsuitable cover lens.

Grinding Visor Replacement Lenses

Some helmets incorporate a separate grinding visor.

The Weldclass WC-06709 is listed as a 220 × 120mm inner grinding visor lens for the PROMAX 850R.

It is supplied in a pack of five.

A clear grinding visor serves a different purpose from a welding shade filter.

It must never be treated as an adequate substitute for the approved welding filter.

Retainer Frames & Mounting Parts

A correctly specified lens still needs a secure mounting arrangement.

The WC-05330 retainer frame with hook/latch is listed for PROMAX 180, 200 & 350 helmets.

If a retainer is cracked, loose or damaged, replacing only the cover plate may not resolve the problem.

Inspect the frame, clips, latches & surrounding helmet structure.

Use only manufacturer-approved replacement components.

Never rely on improvised fasteners to secure protective lenses.

Magnification Lenses for Detailed Work

Some operators benefit from magnification during fine welding tasks.

The Weldclass P7-ML20 is listed as a 2.0-dioptre magnification lens measuring 108 × 51mm.

A compatible insert may assist with close viewing.

However, magnification is not a substitute for the required welding filter.

Confirm the approved mounting arrangement plus suitability for the operator's visual requirements.

Sweatbands & Headgear Comfort

A helmet should remain securely positioned during work.

The Weldclass 7-FFSB is listed as a replacement sweatband for specified flip-front helmets & faceshields.

Replacing a worn sweatband may help maintain comfort within compatible headgear.

However, a sweatband cannot repair damaged adjustment mechanisms.

Inspect the complete headgear assembly whenever fit or positioning becomes unreliable.

PROMAX PAPR Filters & Spares

Powered air-purifying respirator systems require particular attention to compatibility.

The collection includes selected PROMAX R50 components:

• WC-06705: Carbon prefilters, pack of five.

• WC-06704: Main particle filter.

• WC-06695: Lithium-ion battery.

• WC-06699: PROMAX 850R face seal.

• WC-06711: PROMAX 680R face seal.

These are not universal respiratory accessories.

Use only manufacturer-approved parts & follow the complete system's inspection, maintenance, airflow & operating requirements.

Replacement Lens or Complete Helmet?

A worn outer cover may only require an approved replacement if the remaining helmet is serviceable.

A damaged retainer may be replaceable when the correct part is available.

A defective ADF requires appropriate assessment & replacement.

Damage to the shell, headgear or essential protective components may require more extensive action.

If the helmet cannot be restored to its approved configuration, it should not be used.

Five Checks Before Ordering Helmet Spares

Identify the helmet model

Check the exact PROMAX series or other manufacturer reference.

Find the original part number

Use the manufacturer's replacement code wherever possible.

Confirm the component type

Outer cover, inner cover, ADF, grinding visor & retainer are different items.

Check the dimensions

Measurements help confirm a match but do not prove compatibility.

Review the pack quantity

Some replacement lenses are sold in packs of five or ten.

For related equipment components, browse Weldclass Torches & Accessories.

Cleaning Welding Helmet Lenses

Correct cleaning helps maintain visibility without unnecessarily damaging optical components.

Inspect the lens before wiping it.

Grit or abrasive contamination can scratch protective surfaces.

Use only cleaning materials approved for the specific lens.

Avoid unsuitable solvents, aggressive scrubbing or excessive heat.

Store unused replacements in protective packaging.
