Understanding TIG Welding and the Role of TIG Consumables

TIG welding is a process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas, usually argon or helium. TIG consumables include items such as tungsten electrodes, nozzles, collets, collet bodies, and gas lenses. These components are critical for ensuring smooth and efficient welding operations.

Frequently Asked Questions

What tungsten electrode types does Lincoln Electric carry and which should I choose?
Lincoln's PIM catalog lists three Premium Tungsten lines: 2% Lanthanated (gold band, KP4721 series), 2% Ceriated (gray band, KP4722 series), and WX Multi-Oxide (KP4723 series), all available in diameters from .020 in. to 5/32 in. in 7 in. lengths. Lanthanated tungsten is the most versatile choice for both AC and DC welding on aluminum, steel, and stainless. Ceriated is excellent for low-amperage DC applications (thin stainless, aerospace parts). WX Multi-Oxide is a non-radioactive thorium alternative that handles a wide amperage range on DC. Neither lanthanated nor ceriated contain radioactive thorium, making them the preferred options over older thoriated electrodes for indoor shop use.
What is the difference between a gas-cooled (air-cooled) TIG torch and a water-cooled TIG torch?
Gas-cooled (air-cooled) TIG torches are cooled by the flow of shielding gas through the torch body and are rated for continuous use up to approximately 150–200A, per the Air Products Welders Handbook. At currents above 150A, the torch body and nozzle require water cooling. Water-cooled torches are rated for 300–500A continuous, and some large models handle up to 1000A for mechanized welding. Choose a water-cooled torch any time you are welding above 200A continuously or running long, repetitive passes.
What sizes and types of collets and nozzles should I stock for a Lincoln PTA-17 TIG torch?
The PTA-17 series (K1782 family) is a medium-duty air-cooled TIG torch that accepts standard 17-series consumables, which include collet bodies, collets, alumina cups (sizes #4 through #8 are the most common), and gas lenses. Match the collet and collet body bore to your tungsten diameter — for example, a 3/32 in. tungsten needs a 3/32 in. collet. AWS Table 3.1 shows medium torches accommodate electrode diameters of 0.040 in. to 5/32 in., aligning with the PTA-17's capacity.
When should I use a gas lens on my TIG torch?
A gas lens replaces the standard collet body and uses a stainless mesh screen to diffuse shielding gas into a laminar, turbulence-free column. This significantly improves shielding coverage, especially on stainless steel, titanium, or aluminum joints where oxidation is a concern. Gas lenses also allow you to extend the tungsten further from the cup for better visibility in tight joints. The tradeoff is slightly higher gas flow requirements and a larger cup diameter compared to standard setups.
How do I sharpen a tungsten electrode for DC TIG welding, and does tip geometry matter for AC?
For DC TIG welding (DCEN, used on steel and stainless), grind the tungsten to a sharp point with the grind lines running lengthwise — not circumferentially — to improve arc initiation and directional stability. A taper of roughly 2.5x the electrode diameter is a common starting point. For AC TIG welding aluminum (used on most aluminum with AC TIG machines), the tungsten forms a balled end on its own due to the EP half-cycle; starting with a freshly prepared balled or slightly rounded tip avoids the ball forming off-center.
What shielding gas flow rate should I use for TIG welding with a standard air-cooled torch?
For most manual TIG welding on steel and stainless with a standard alumina cup (size #6–#7), argon flow at 15–25 CFH (7–12 L/min) provides adequate shielding. For aluminum, run 20–30 CFH (9.4–14.2 L/min). When using a gas lens, you can often reduce flow by 20–30% and still get excellent coverage. Excessive flow causes turbulence that draws in atmospheric air and actually worsens shielding — more is not always better.
