With these considerations in mind, how can a CNC plasma operator wear glasses as dark as a welder’s shield and still see enough to get anything done? the arc is moving, and the operator is not always looking in that direction.the operator needs to be able to see the machine control as well as the overall machine while the arc is on.

the operator needs to move around, so he must be able to clearly see his surroundings (it would be rather unsafe to walk around the shop under a welding helmet).the operator is often much farther away from the arc.Operating a CNC machine is a little different: So how do you apply that to operation of a? When you are welding, you pretty much stand still and look at the weld zone through a helmet, so you can manually operate the welding torch that is just inches away from your face. Then, go to a lighter shade which gives a sufficient view of the weld zone without going below the minimum”.īy comparison, the ANSI recommendations for SMAW, GMAW, and FCAW welding are all in the shade 10 – 14 range also. In both cases, the recommendations offer the rule of thumb to “start with a shade that is too dark to see the weld zone. The protective shade numbers refer to the darkness shade of safety glasses or welding shields, the higher the number the darker the glass.ĪNSI and the American Welding Society (AWS) publish a slightly more detailed chart, in ANSI Z49.1:2005 Safety in Welding, Cutting, and Allied Processes. The following information comes from the OSHA Fact Sheet “Eye Protection against Radiant Energy during Welding and Cutting in Shipyard Employment”, and also references the ANSI numbers. There are a few sources of recommendations that everyone should be aware of. Recommended eye protection for plasma cutting Needless to say, looking at an arc that intense can easily cause eye damage, including permanent damage leading to blindness. Plasma cutting arcs can also be very intense, because the arc current is typically anywhere from 100 to 800 Amperes. A plasma cutting arc, like any electric arc, gives off a broad spectrum of electromagnetic radiation, which extends all the way from Infrared light (IR), through the visible spectrum, and into the Ultra Violet (UV) range.
