RIVERWELD TIG Gas Lens Collet Bodies 10N 45V series Large Diameter Long Alumina Nozzle Ceramic Cups 10N 54N series Assorted Size Kit Fit QQ300 PTA DB SR WP 17 18 26 TIG Welding Torch 50pcs

Application is a 2016 AHP AlphaTIG, which has the 17 series torch. Everything looks high quality, and the shorter backers will work nicely for fitting into tight areas. I have no actual data to support better gas coverage (although I've seen pictures online demonstrating the difference in flow between the two types) but I've experienced no issues, so it seems to be working just fine. Definitely worth it if for no other reason than to have spares when you break something, and definitely worth having the shorter caps available.

Perfect kit to restock my welder with a verity of cones

My son thinks they are a great value and work perfectly.

Very large assortment,should last a long time.

I got a nice full set of gas lenses with all of the associated collets and cups, along with a new plastic ring for my torch even though the lenses fit with my old one (stock torch from AHP 200 tig/stick welder).I noticed an immediate improvement in gas coverage compared to not using lenses, and actually held a more consistent arc than my original collets.Very impressed and worth the money imo.

The kit works fine its just kinda pain to deal with, you need to use multiple insulators to make certain cups work. If youre in a pinch and cant or wont spend the money on a good kit this kit would do fine. It would he a good kit for someone that wants to try different style cups before making an expensive commitment or if you have a job that requires a few of the oddball cups in this kit.

All the TIG torch parts I’ve purchased over the last several years have been Riverweld. I notice no difference between them and the much more expensive ones that come with the blue machines, except the labels.

Works and fits great and nicely priced
