3M Speedglas have been conducting extensive research into designing a welding helmet that is constructed to be reliable and extremely adaptable to a welder’s needs and situation. The result of their research is the G5-01 Welding Helmet. Please note that this product comes with just the welding helmet with neck and head protection, but no welding filter.

The G5-01 clear protective visor dimensions are 104 x 170mm, offering a massive range of viewing ability, plus its curves provide excellent views up, down and superficially. The model’s slim profile and ergonomic design make the G5-01 more lightweight and easier to squeeze into the tightest spaces whilst also retaining its comfort. Mould the helmet to suit your individual needs with 3M branded additional accessories such as different types of protection covers.

Built for heavy-duty, high-amperage welding and grinding, this innovative series of welding helmets are constructed to offer welders more control over their airflow direction. The design of the helmet allows the airflow to be directed to your face, your visor or a combination of both, whatever the welder prefers. All adjustments made to the airflow are possible whilst wearing the helmet. The helmet’s flip-up function allows an effortless switch between welding and grinding applications whilst also staying protected due to the powered air respiratory system.

Speedglas 9100 Adflo Parts FAQs

Straight answers to the questions people ask most when choosing and looking after spare parts for a powered air welding helmet with an auto-darkening filter.

How often should I change the outer protection plate?

There is no fixed interval. Change it when spatter, scratches or grinding dust make it hard to see through, or when it has pitted or cracked. A dirty or damaged plate forces you to lean in and strain, which is a safety issue as well as a comfort one.

Outer plates are the sacrificial layer that protects the filter lens, so it is sensible to replace them freely rather than risk scratching the lens itself. Heat-resistant and scratch-resistant types exist, and the right one depends on how much spatter and grinding your work produces.

How do I choose the right shade range for a replacement auto-darkening filter?

The shade you need depends on the process, the current and the brightness of the arc, so work from the welding procedure or your risk assessment rather than a guess. Many filters offer a fixed low shade for grinding or setting up and a variable range for welding.

A wide variable range covers most MIG, TIG and stick work. Check that the replacement has the same outline size as the original, and that any upgrade or replacement kit is listed as suitable for your helmet version, as the fittings can differ.

Which filters do I need for the powered air unit, and when do I replace them?

The unit normally needs a particle filter for welding fume. Where there are gases or vapours, such as solvents, a suitable gas filter can be fitted as well, and some systems use an odour filter or a spark guard for added protection. Choose the filter type from your workplace risk assessment, not from habit.

Replace a particle filter when it is damaged, clogged, or when the unit's airflow warning shows that airflow has dropped. Pre-filters trap larger dust and are changed more often, which helps the main filter last longer.

What does an airflow check tell me and how do I use it?

Powered air units are designed to supply a minimum airflow to the helmet, and the maker supplies a method of checking it, such as a flow indicator or a test described in the manual. Follow the instructions for your own unit exactly, and carry out the check at the intervals the maker specifies. Many users also check at the start of each shift and after changing a filter or battery.

If the airflow is low, common causes are a clogged filter, a part-charged battery, a kinked or damaged hose or a poorly fitted connection. Do not weld until the cause is found and the airflow is back to the level the manual requires. Never ignore a low-flow warning.
