Warning
serious
personal
injury
A risk of exposure to toxic elements, like zinc selenide, may result
when certain optical or beam delivery components are damaged. In
the event of damage to laser, marking head, or beam delivery optics,
contact SYNRAD, Inc. or the optics manufacturer for handling
instructions.
When the application requires air (instead of nitrogen) as an assist gas, we recommend the use of breath-
ing quality air available in cylinders from a gas or welding supply company, Because compressed shop air
contains minute particles of oil and other contaminants that will damage optical surfaces, it must be care-
fully filtered and dried before use as a purge or assist gas. Refer to Table 3-1, Assist gas purity specifications, in
the Technical Reference chapter for filtering and drying specifications.
