Weld Shields
Figure 186 - Weld Shield Dimensions
The GuardShield safety light curtain weld shields are sold in the same lengths as
the protective field heights of the GuardShield safety light curtains. These
polycarbonate weld shields are designed as disposable devices whose purpose is to
help protect the front window of the GuardShield safety light curtain from
damage.
One weld shield reduces the operation range by approximately 10%. For a 450L
with finger resolution with a weld shield that is installed on each stick, the
maximum range of operation reduces to: 7.0 m (22.97 ft) x 90% x 90% = 5.67 m
(18.61 ft). The installation of the weld shields does not affect the minimum
operation range.
