With the Speedglas G5-01, you move from welding to grinding without changing equipment: once the welding shield is flipped up, the inner visor is what stays in front of your eyes. The 46-0700-51 is that replacement visor. It carries a dual anti-fog and scratch-resistant treatment, designed for the two common causes of poor visibility during finishing: fog forming inside the helmet and marks left on the surface. When the original visor is scratched, pitted or cracked, replacing it restores a clear view of the grinding wheel, the tool and the edge of the workpiece. It is a part of the helmet itself, separate from the plates that protect the welding filter.

Features and benefits for the welder

• Anti-fog and scratch-resistant coatings on the same visor, for a clear view during finishing work.
• Smooth switch from welding to grinding on the G5-01, with the same protection on your head.
• Clear polycarbonate: a sharp window on the wheel, the tool and the workpiece edge.
• Bag of 5 visors to maintain several helmets or plan the next replacements.
• Targeted replacement: the marked visor is changed on its own and the rest of the helmet stays in service.

Applications and assembly compatibility

This visor is designed for the G5-01 (RG501) welding helmet, used in general manufacturing, industrial maintenance, metal processing and heavy infrastructure sites. It supports grinding, metal repair and metal processing as well as the welding phases. For the welding optics, the inside covers of G5 auto-darkening filters remain separate parts, chosen according to the filter fitted in the shield.

Fitting and checking 46-0700-51

The G5-01 instructions describe how to replace the inner visor. Place the visor in its frame, engage every retainer, then close the assembly and check that it is properly locked before getting back to work.

Care and replacement

Clean the visor gently to preserve its coatings. If an area stays cloudy after cleaning, or if a crack, pit or scratches interfere with your view, fit a new visor. Use the opportunity to check the condition of the frame that holds it.

Safe use

The visor protects your face during grinding in the complete G5-01 helmet; for welding, lower the shield fitted with its filter. A cracked visor is replaced before any further use.

FAQ: the 46-0700-51 part

Which helmet does the 46-0700-51 visor fit?

The Speedglas G5-01 helmet, where it replaces the original clear inner visor.

Is it the same part as a filter inside cover?

No. The visor covers the helmet window for grinding, while the 06-0200-21 and 06-0200-40 covers protect the matching G5 filters directly and are ordered separately.

Why an anti-fog and scratch-resistant visor?

Fog and scratches are two common causes of visual discomfort during finishing. The two coatings help keep your view clear, especially during long grinding sessions.

How many visors are in the bag?

The bag holds 5 visors, enough for several replacements or to maintain several G5-01 helmets in the shop.

Which other G5-01 parts should I check at the same time?

The visor frame, the hinge mechanism and the headgear are worth a look too; these replacement parts appear in the suggestions below.

Complementary suggestions

Behind the G5-01 grinding visor, the welder keeps SecureFit SF202 glasses (YASF202) and a flame-resistant Nomex cap (V308). Split and full-grain leather welding gloves (G602), MAX earplugs (OA1100) for grinding and a flame-resistant FR-Tech shirt (V129) complete the outfit. During grinding, the welding shield may be raised, but the clear grinding visor must remain lowered in front of the face. Check the stability of all equipment worn together.

To maintain the same G5-01 helmet, inspect the outer visor frame (R46-0700-63) and the hinges (R46-0400-56) when replacing the visor. The headgear (R46-0400-51) is replaced separately to maintain the helmet fit. The face seal (R46-0099-28) and the comfort headrest (R46-0400-55) complete the components to examine before returning the helmet to service.
