variable shade welding lens model YC-K is presented for distributor and industrial sourcing review. Use the product image and available specifications to define the request, then ask for a current quotation and written confirmation of the supplied configuration.
An auto-darkening filter has several procurement variables that should not be collapsed into one label. The available information may include viewing area, shade states, control method, arc sensors, switching time, power supply and a matched helmet. Read each field separately. A similar external size does not establish interchangeability, and a listed helmet pairing does not establish cross-brand compatibility.
Wide shade coverage with digital adjustment
YC-K lists a 75 by 112 mm viewing area, four arc sensors and digital display controls. Its ranges are divided by task: DIN 3 light and grind states, DIN 4-8 cutting shades, and DIN 9-12 or 13-15 welding shades. A buyer should state which range matters instead of requesting only a variable shade welding lens.
The source also lists two CR2450 batteries, solar-cell battery assist, sensitivity adjustment from 1 to 10 and a dark-to-light delay from 0.1 to 1.0 second. Ask whether batteries are included, how the memory or digital interface is configured in the quoted version and which helmet shell is proposed with the filter.
Compare, assess and request
The wider auto-darkening filters catalog helps buyers compare model identities within the same family. Similar names, dimensions or photographs do not establish interchangeability. Review the related product or family record before selecting a configuration.
Product identification is separate from workplace selection. OSHA publishes welding eye and face protection requirements and shade-selection guidance. Read the welding helmet shade guide and the underlying OSHA welding requirements. These safety references do not certify a catalog model.
Prepare the RFQ
Name YC-K, the planned process, desired controls or viewing area, quantity, destination and document requirements. Confirm minimum order, lead time, package contents, spare components and any helmet or filter pairing. If you are replacing a part, include the current model and measured dimensions. Then send a model-specific request so sales can respond against a defined scope.

Questions for YC-K
Is the pictured configuration the standard package?
No package is inferred from a photograph. Ask sales to list the included model, controls, headgear, filter, lenses, PAPR components and accessories for the quotation.
Does this model fit another brand or helmet?
Provide the target model and dimensions for written compatibility confirmation. Similar appearance or dimensions do not prove fit.
Are the required documents current?
Request the current document set for the quoted model, configuration and destination. An older product-page label is not a substitute for document review.
