What is TIG gas lens?
A gas lens will replace the collet body in a TIG torch. Together with the collet, the gas lens will hold the tungsten in place to create the electrical contact needed for good electrical conductivity. Usually, a gas lens is composed of a copper/brass body with layered mesh screens of steel/stainless steel.
What is the best tungsten for TIG welding?
Ceriated and lanthanated tungstens hold up better for AC TIG applications than 2% thoriated tungsten. While thoriated tungsten remains the most common in DC TIG, because of concerns about radiation, most experts strongly recommend ceriated or lanthanated electrodes for AC and DC TIG.
How do I know my TIG cup size?
The size of the weld area will determine how big of a cup you need. A large weld area will require a larger cup size as more gas will be required to fill the puddle. A small weld area can use a smaller TIG cup size as less gas is needed to weld the joint.
How many CFH do I need for TIG welding?
While gas flow rates for TIG welding are typically between 10 cfh and 35 cfh, the rate is impacted by the consumables being used and atmospheric conditions. First, be aware of how the shielding gas interacts with atmospheric gases.
What are the different TIG torch sizes?
TIG torches come in a number of set sizes: 9, 17, 18 & 26. These, generally, are in numerical order, in that 9 is the smallest size torch and 26 is the largest. ‘Generally,’ because the size 20 torch is the water-cooled version of the size 9 (but UNIMIG doesn’t sell that torch).
What is the best tungsten for welding aluminum?
In summary, follow these three recommendations: Use a pure tungsten or zirconiated tungsten electrode when AC welding aluminum. Don’t use a 2 percent thoriated tungsten electrode. Make sure you use a tungsten electrode large enough in diameter to carry the welding current you plan to use.
Why are TIG cups pink?
The most common TIG cups are made of Alumina Oxide and are “pink” in color. Alumina is a high- temperature, nonconductive pink ceramic material. This material is injection-molded and mass-produced, which is why the alumina nozzles are less expensive than those made with other materials.
How do you pick a TIG cup size?
What is the purple tungsten?
Rare Earth (Purple) Electrodes The innovative Rare Earth Blend tungsten electrode contains 98.34% tungsten, 1.5% lanthanum, 0.08% Zirconium, and 0.08% Yttrium. It is the perfect substitute for red thoriated electrodes.
Is TIG stronger than MIG?
Bottom Line. TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.
