Definition - What does Hand Shield mean?
A hand shield is a type of welder’s mask. Like a standard welder’s shield, it covers the face from the lower jaw to the brow line, with an opening to accommodate standard welder’s protective lenses. However, rather than being a wearable piece of safety equipment – one is equipped with a headband which allows the welder to work hands-free – the hand shield has a handle attached to it. The welder grasps the handle and holds the hand shield over their face.
Trenchlesspedia explains Hand Shield
The hand shield has limited usefulness. Because it doesn't allow a welder to work with both hands, it's most useful when making spot or repair welds. Under limited circumstances, a hand shield may be used when making welds with MIG or similar gun-type welding machines. The hand shield is more useful to persons who – while involved in the welding process, such as supervisors, inspectors or quality assurance personnel – don't participate directly in the welding process.
