What are Pyrex TIG cups for?

With an Arc-Zone Gas Saver Pro™ Kit you can produce high-quality welds on a consistent basis for a variety of TIG welding applications. The Pyrex glass nozzle offers excellent visibility of the weld puddle and the tungsten electrode– ideal for inside corners, pipe and tube clusters etc.

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.

What size TIG Cup do I need?

The standard #5 cup is a go to cup for a lot of really good tig welders. One of the main benefits to using a #5 cup is argon savings. a setting of only 12-14 cfh works in most situations. For me, the #5 cups work great for 1/8″ and thinner aluminum.

How are TIG cups measured?

The gas outlet or “orifice” of a TIG gas nozzle is measured in 1/16” (1.6mm) increments. For example a #4, is 1/4”, (6.4mm). TIG Nozzle & Cup Types: Pink Gas Cups: The most popular TIG cups, made from premium “ZTA” (Zirconia Toughened Alumina) oxide for general purpose applications.

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.

How do you pick a TIG cup?

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 do you pick a TIG Cup?

Why is my TIG arc yellow?

Issue 4: Yellow Powder or Smoke on Cup—Tungsten Discolor Incorrect shielding gas or mixture. Use argon gas. Helium or Argon/Helium blend gasses are also acceptable but not required.

Why is my TIG welder melting my tungsten?

Too large of tungsten for the given amperage can cause the arc to rotate around the tip, while too small of tungsten can melt and cause the arc to become unstable. Always follow the manufacturer’s recommended welding parameters for each tungsten electrode diameter.

What is GREY tungsten used for?

Grey electrodes perform well in DC applications and are great for welding titanium, copper, magnesium, aluminum, and nickel alloys, as well as non-corroding and stainless steels.
