Straight answers to the questions people ask most when upgrading a welding helmet to work with a powered air unit.
An upgrade kit is a helmet, or set of helmet parts, that is built to connect to a powered air respirator unit you already own. It adds the air duct and internal parts so that filtered air from the blower flows into the helmet, turning a standard welding helmet set-up into a powered air one.It is a way of adding respiratory protection to a welding helmet without replacing the whole air system, as long as the parts are compatible with your blower.
Check the make and model of your blower unit against the compatibility information published by the maker of the helmet and the blower. Connectors, fittings and approvals can differ between models and between older and newer generations, so never assume that two parts that look similar will work together.Look for the model number and any date or batch marking on the unit, and compare it with the maker's compatibility list. Some combinations may need an adapter and some may not be approved at all. If you are not sure, our team can help you check before you order.
Not necessarily, but check what you have. Filters have a limited life and should be replaced as the maker directs or if they are damaged, clogged or old. A breathing tube that is split, kinked or worn should be replaced, whatever the kit includes.Use only the filters made for your blower and suited to the hazard you work with. Fume and gas hazards need different filters, so check your risk assessment.
The helmet in a kit may come with a filter or without one, depending on the version. If it has no lens, you will need to choose a suitable auto-darkening filter that fits the helmet and suits the welding you do.Think about the processes, the current range and the shade you need. Filters are matched to a helmet's frame, so make sure the one you choose is intended for it.
