TIG Gas Lens Back Cap Collet Body Assorted Size Kit Fit PTA DB SR WP 9 20 25 TIG Welding Torch 63pcs

These work great for reasonable price

I am a beginner TIG welder at Los Angeles Trade Technical College about to complete my A.S. in Welding.For the past few months, I have been welding with a traditional ceramic cup that comes with most machines and it has worked out fine. I bought this kit because I plan on specializing on TIG and I'm anticipating exotic metals.In class, I tested this kit on a Lincoln Precision TIG 275 with a wp20 water-cooled torch. I was welding 3/32" aluminum and using a green tipped tungsten.With traditional cups, I always noticed a red-ish color around the tungsten while the electricity is ionizing the argon gas. The red was from uneven flow which would usually go away once more amperage is applied. So it takes a little more amperage to get to the "sweet spot".With the gas lens, I never saw that red-ish color. The gas flow was perfectly even around the tungsten even at low amps. It also helped a little bit with arc stability and shielded the weld pool nicely.I played with stickout. Depending on angle, I got a half and inch stick out on a t-joint and was surprisingly able to get adequate gas coverage.With a closer or regular stickout, the arc is very stable and does not wander as much.This product is awesome. It will not make you a better welder. But if you plan on doing a lot of TIG welding just buy this right now.But it will give you the ability to weld more types of metals (the big cups I think are for titanium, stainless, chrome-moly, etc...), the ability to weld in tight places a little easier, and it will generally make your welds more consistent because the gas flow is consistent.

I bought the 63 piece kit. The cups all look fine and there is an excellent assortment of them. I have had issues with the gas lenses. On them same torch, if I use a regular collet, it welds OK. But when I switch over to the gas lens, it welds like there is contamination. This is using a CK200-RG torch in a water cooled welder. My tungsten rods were burned to the tip.I did contact the manufacturer. Their did respond and were fairly quick on the response, but no resolution. I ended up purchasing CK gas lenses and the issue was resolved.

I thought I would never use some of these but I was wrong! Some of these are so useful it’s crazy that I didn’t buy them a long time ago! Had them for 6 month now, only one broke after dropping the water cooled lead (heavy) 6 feet!
