Not too sure which helmet is right for you? Check out our welding helmet buying guide to help you choose!
Straight answers to the questions people ask most when choosing a welding or grinding helmet with a powered or flow-controlled air system.
A powered respirator unit is a belt-worn blower with a battery that filters the surrounding air and passes it to the helmet. A compressed-air system feeds clean breathing air from a supply through a flow-control unit.A battery unit gives freedom to move without a hose to a fixed supply. A compressed-air system needs a suitable air source and clean, properly filtered air, but has no battery to charge. Choose by the work, the site and what you already have.
A welding helmet has an auto-darkening filter for arc work. A grinding helmet has a clear visor and is built for impact from particles and sparks.If you do both, you can use a welding head for arc work and swap to a grinding head on the same blower, if the system allows. This is often easier than a single compromise helmet.
The shade range shows how dark the filter can go and how light it is in the clear state. A range that starts at a low shade is good for low-current work and for seeing before the arc starts, while higher shades are for heavy current.Choose a range that covers your processes and currents. A variable shade control gives more flexibility.
Larger filters give a bigger view, and more arc sensors reduce the risk that the filter fails to darken when the arc is hidden, for example in awkward positions. Advanced filters add features such as adjustable sensitivity and delay.If you weld out of position or at low current, look for a higher specification. For general work a simpler filter can be enough.
Most units have an indicator, an alarm or both to show low flow or a low battery. A flow test with the test device, or the method in the manual, should be done before each shift.If the flow is low, check for a clogged filter, kinked hose or a flat battery. Do not weld until the correct flow is restored.
Facial hair under a seal can let contaminated air in, so tight-fitting masks need a clean-shaven face. A loose-fitting powered helmet or hood does not rely on a seal, so it can be used with facial hair, but check the maker's guidance for your own helmet.Spectacles often fit under the helmet, but check clearance and comfort. Make sure nothing blocks the airflow around the face or lets contaminated air reach the breathing zone.
