TIG Torch Gas Lens Kits
If you are looking for a TIG torch gas lens , the first thing you need to know is what style tig torch you have.
The easiest and quickest way to identify your tig torch is to take a quick look at the collet and collet body.
If your Collet body is almost 2 inches long, then you have a 17,18,26 style tig torch.
...and if your collet body is slightly less than 1 inch long, then you have a 9 or 20 style torch. ( and a 9/20 weldmonger gas lens kit is the kit for you)
If you have an air cooled tig torch, odds are it's a 17 style because that a 17 style air cooled torch the most common torch that comes with a 200 amp and under tig welding machines.
Standard cups with standard collet bodies work OK with short tungsten stickout but sometimes you really need to extend the tungsten to reach a weld.
Along with being able to use a longer stick out, Better gas shielding is a big benefit.
When stainless steels and other alloys are not shielded enough, the puddle gets oxidized.
Then the puddle gets sluggish and does not flow easily.
That makes for a dark grey weld that might even lose it's stainless properties.
In other words, a weld turned dark but polished might start rusting within a few weeks or months.
Welders who regularly work in the sanitary stainless industry can not afford to get a bad reputation from stainless welds that rust later.
The #8 stubby gas lens does a much better job than a standard #8 cup with the tungsten extended 1/2" on both.
And a jazzy #10 cup with secondary diffuser screens will work even better than the #8 cup making a very clean weld with very little discoloration.
Discoloration on plain carbon steel weld might not be a problem at all.
But excessive discoloration on a stainless weld can compromise the stainless properties.
A tig torch gas lens kit can help.
