How do I know what size TIG torch I need

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).

Are TIG torch collets interchangeable?

The TIG collet body screws into the torch body. It is replaceable and is changed to accommodate different size tungsten electrodes and their respective collets.

What are the different types of TIG torches?

There are two main categories of TIG torches: Air/gas cooled and water cooled. The main TIG torch types are detailed below.

How do I know what kind of TIG torch I have?

Most tig torch manufacturers stamp a model number on the neck of the torch. The numbers are often preceded by letters, WP, SR, ER for example. These letters can usually be ignored as it is the number that is important when selecting the correct parts from this section.

What size is a t2 TIG torch?

What makes a good TIG torch?

The TIG welding torch needs to be rated to at least the same amperage as the welder, preferably higher. So if your TIG machine is rated at 250 amps, you need a torch with at least a 250-amp rating. Otherwise, it’s going to overheat, causing a failure and possibly even burning you.

What is scratch start TIG?

The scratch start TIG welding arc is initiated by scratching the sharpened tungsten against the steel being welded. Similar to starting a stick arc, it is a quick scratch and then a lift to initiate the welding arc. … Once this is done, the welder pushes the foot pedal or switch to initiate the arc.

What is a Euro TIG torch?

ERGOTIG is the standard range of TIG welding torches. ERGOTIG is the historical range of TIG welding torches by Trafimet and was the first to adopt new ergonomic solutions such as the handle ball joint, the same solution that is now adopted by the TOP of the range as the torches TPRO.

How far can you extend your tungsten beyond the cup?

You can use gas lenses to weld all materials is you want; they also allow you to stick your tungsten up to 1” out of the cup by increasing gas flow. Sometimes you need to extend it just to reach a tight spot.

What is tungsten electrode?

Introduction. Tungsten electrodes are used when arc welding with the Tungsten Inert gas (TIG) process or when plasma welding. … A tungsten electrode is used because it can withstand very high temperatures with minimal melting or erosion. Electrodes are made by powder metallurgy and are formed to size after sintering.

What is a water cooled TIG torch?

Weldcraft Water-Cooled Torches are ideal for welding amperages above 200 amps at a high duty cycle. Weldcraft Water-Cooled Torches are made with the highest quality components to maximize the durability and performance of the machine. …

What is the smallest TIG torch?

MR70 MICRO TORCH™ GAS COOLED The Micro Torch is the smallest and most versatile TIG torch on the market! These torches come complete with kit and accessories to help make your job easier.

What is a TIG gas lens?

Gas lenses are a TIG welding accessory which improve the gas flow through a TIG welding torch. Improved gas flow is achieved by use of various types of openings through which the shielding gas passes on its way through the TIG torch.

How are GTAW torches rated?

What is up with the numbering system of tig torches? A small air cooled tig torch rated for 125 amps is called a #9 style. The same size torch in a water cooled model is a #20 style torch and its usually good for 250 amps. The same size torch in a water cooled model is a #18 and its usually rated around 350 amps.

Why is my TIG torch getting hot?

Running a torch beyond its recommended amperage rating can cause it to overheat. … Lack of sufficient gas flow (air-cooled torches) or water flow (water-cooled torches) will result in an under-cooled torch. Using a power cable gauge that is too low will cause the wire to heat up and melt.

Are CK TIG torches good?

Our standard line of TIG torches are high-quality adaptations of the industry classic torches, made by The Linde Group, such as the 9, 17, 18, 20, 24, and 26 styles. … MasterTIG torches are the highest quality TIG torches available on the market as they include the most cuttingedge designs created by CK Worldwide.

Can you use a water cooled TIG torch without water?

Do not try to use your water cooled torch without running water through it or you will burn it up even at very low amps. An air cooled torch is made with a heat sink to dissipate the heat for cooling. The water cooled torch does not have that.

What does Wp stand for in TIG welding?

Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium).

Can you TIG aluminum without high frequency?

The short simple answer is for transformer type TIG welding machines and normal aluminum welding, yes you need continuous HF stabilization in conjunction with and adjustable AC waveform. With inverter type TIG machines the polarity changes so rapidly that continuous HF is not necessary to maintain the AC arc stream.

What does lift arc TIG mean?

Lift-Arc™ is a method of starting the arc when TIG welding that enables the operator to touch the tungsten to the work piece, lift it off the work piece, and then have full welding current begin flowing.

Can you TIG weld aluminum with a DC TIG welder?

DC GTAW can work very well on aluminum, so don’t be afraid to try it. Just be aware that the technique is different than that used for AC.

How far should the tungsten electrode be sticking out of a number 7 ceramic cup?

As a general rule, I would have around 5-6mm of the Tungsten sticking out of the Ceramic Gas Shroud. The important thing is that gas shield integrity around the arc is maintained.

What is the difference between red and green tungsten?

Color code and what it means The main colors/varieties of TIG electrodes and their American Welding Society abbreviation are as follows: Green (EWP) = Pure Tungsten, Orange (EWCe-2) = 2% Ceriated, Red (EWTh-2) = 2% Thoriated, Gold (EWLa-1.5) = 1.5% Lanthanated, Brown (EWZr-1) = 1% Zirconiated.

How many types of tungsten electrodes are there?

Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding (GTAW). In addition, tip preparation is critical. The electrode choices are pure tungsten, 2 percent thoriated, 2 percent ceriated, 1.5 percent lanthanated, zirconiated, and rare earth.

Is purple tungsten good for aluminum?

This rare earth tungsten offers excellent ignition characteristics and consistent welding properties. They are universal and suitable for all applications in the whole range of AC and DC welding of non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys.

What is an advantage of a water cooled TIG torch?

Water cooled torches have longer duty cycles without damaging the equipment. A water cooled torch is easier to hold and the welder doesn’t have to rush to finish the weld before the torch gets hot.

Can you use antifreeze in TIG cooler?

Salty, Distilled water is factory recommended for temperate climates. Hooda, green and other auto antifreezes have a problem with “robbing” HF, making starts more difficult. RV or the stuff made for tig coolers is the only recommended product.

What is an advantage of liquid cooled torches compared to gas cooled torches?

Water-cooled welding torches use a radiator cooling system to circulate coolant, ambient air, and shielding gas in order to expel heat from the torch. Cables for water-cooled torches contain less copper than air-cooled, making them lighter and more flexible to work with.

What is micro TIG welding?

Micro TIG welders are also known as Pulse-arc welders. Pulse-Arc welding or micro TIG welding uses electrical energy to create a plasma discharge. The high-temperature plasma, in turn, melts metal in a small spot. This process takes place in milliseconds.
