What does the number on a TIG Cup mean?
Why use a different TIG cup size? Different sized cups have their pros and cons. The larger the cup, the more gas is available and the harder it is to move around. The smaller the cup, the more mobile it will be and easier it to maneuver in tight spaces.
What determines TIG cup size?
if i am welding 1/8″ or thicker, i often use a 4 or 5 cup and only 10-12 cfh and it works fine on carbon steel. the size cup is largely determined by accessibility to the weld and material type. for example, titanium requires an extremely large cup because it cant tolerate oxidation of the weld pool at all.
What do the numbers mean on TIG torches?
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).
How is the opening of a TIG cup measured?
The gas outlet or “orifice” of a TIG gas nozzle is measured in 1/16” (1.6mm) increments.
What size tungsten do I need to weld aluminum?
The Electrode Size for TIG Welding Aluminum You often need to consider a 1/8” electrode for welding aluminum in order to get enough heat and to create a stable arc. Too small an electrode will create a sloppy weld. If you’re working on AC with a lanthanated electrode, you may be able to use a 3/16” or 3/32” electrode.
How do you clean a TIG Cup?
Cup can be cleaned up. Use sandpaper ONLY to clean it up. Break the tungsten off with a pair of pliers above the contaminated area, then resharpen.
What color tungsten is best for aluminum?
Green
Pure Tungsten (Color Code: Green) Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium.
What is 2% Lanthanated tungsten used for?
What Are Lanthanated Tuingstens Used For? Lanthanated tungsten can be used for all of the DC welding applications with excellent arc stability at low amperages while maintaining its sharp point well and minimal burn rate in high amperage situations.
What color tungsten is for what?
Pure Tungsten (Color Code: Green) These electrodes form a clean, balled tip when heated and provide great arc stability for AC welding with a balanced wave. Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium.
