Does TIG cup size matter?
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.
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.
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.
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 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.
Can you walk the cup with a glass cup?
Due to the nature of the glass, “walking the cup” is not recommended with the glass Furick Cups. The FUPA 12 is recommended for mild steel, stainless steel, chromoly, titanium, inconel and other space grade alloys.
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.
Why does my TIG tungsten turn black?
If the tungsten electrode turns from its normal color of light gray to a shade of purple or black, that is an indication to increase post-flow time even more. In addition to causing various weld puddle troubles, contaminated tungsten electrode is also the leading cause of an unstable arc.
Can I use GREY tungsten for aluminum?
However, pure tungsten electrodes can only be used in DC for welding aluminum. 2.) 2% ceriated: Seen in the grey coloured label, these electrodes consist of 2% cerium. Usually, these electrodes are used for aluminum in lower amperage DC welders.
How do you ride a TIG welding Cup?
When the cup is inside a groove on inside the 2 members of a fillet weld, the torch handle is just slightly rotated back and forth with very light pressure on the cup. When the cup turns it moves along at an even progression provide a very uniform rate of travel speed.
How do you tell if your tungsten is contaminated?
Tungsten electrode contamination is another common pitfall that can occur during TIG welding. Indications that tungsten electrode contamination has occurred are: one, the weld puddle appears dirty; two, the filler rod does not join or melt smoothly into the weld puddle; and three, the arc becomes erratic.
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.
