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 does the knob on TIG torch do?
Use the knob to select how long you would like your pre-gas to flow before the arc ignites. Start amps: these allow for a lower or higher amp start, depending on your material.What are the basic parts of the torch of oxy acetylene what are their functions?
- Torch. The basic oxyacetylene torch comprises: …
- Hoses. Hoses between the torch and the gas regulators should be colour-coded; in the UK: red for acetylene, and blue for oxygen. …
- Gas regulators. The primary function of a gas regulator is to control gas pressure. …
- Flame traps.
What equipment do you need to TIG weld?
The TIG Set up includes a torch, your choice of an electrode, your choice of hand control or the pedal, and your choice of gas you will be using for your shield. You will also need a grinder to take off any paint or to smooth the surface where you will be welding. TIG is also known as gas tungsten arc welding (GTAW).
What gauge pressure should acetylene never be set above?
Never use acetylene at pressures above 15 psi. Using acetylene at pressures in excess of 15 psi gauge pressure (or about 30 psi absolute pressure) is a hazardous practice.
What does the foot pedal do on a TIG welder?
The foot pedal gives you complete control without having to stop in the middle of a weld and readjust. They can only be used while TIG welding, as stick welding uses an electrode holder rather than a torch and MIG’s amperage is dictated by the wire feed speed.What is a WP17 TIG torch?

This Weldcraft TIG torch is covered with Miller’s True Blue 3 Year Warranty! … A-150 Valve Torch Body. Handle.
What is the switch on a TIG torch?There is just no substitute for precise amperage control without the risk of moving the torch. That said, there are times when a torch switch can be pretty handy. A torch switch is basically an on/off switch so whatever you have the amperage set on the machine is what you get when you press the switch.
Article first time published onWhat 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.
Which are common tungsten electrodes?
- 2% THORIATED.
- AWS Classification: EWTh-2/WT20.
- Principal Oxide: 1.7–2.2% Thorium Oxide.
- Color: RED. …
- 0.8% ZIRCONIATED.
- AWS Classification: EWZr-8/WZ8.
- Principal Oxide: 0.7– 0.9% Zirconium Oxide.
- Color: WHITE.
What are the four types of alloying elements used in tungsten electrodes?
Some of the compounds that can be used with ceriated electrodes include non-corroding steels, carbon, nickel, aluminium, magnesium, titanium and copper alloys. Properties include longevity, excellent arc stability, low erosion rate, good ignition and re-ignition. They should be used at low amperage ranges.
What are the 2 things that are put into the acetylene cylinder other than acetylene?
Fuels. Oxy-fuel processes may use a variety of fuel gases (or combustable liquids), the most common being acetylene. Other gases that may be used are propylene, liquified petroleum gas (LPG), propane, natural gas, hydrogen, and MAPP gas.
Why gas cutting is not possible in stainless steel?
Metals such as aluminum and stainless steel cannot be cut with Oxy/fuel due to the formation of an oxide that prevents oxidation from fully occurring.
Which colour hose pipe is used in acetylene cylinder?
The function of hoses is to provide the passage for gases from pressure regulator to the welding torch. The oxygen hose pipe is coloured black and acetylene hose pipe is red in colour.
When shutting off the torch which needle valve should be closed first?
OXY-ACETYLENE We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel.
Can you store oxygen and acetylene together?
Oxygen storage. Oxygen cylinders shall not be stored near highly combustible material, especially oil and grease; or near reserve stocks of carbide and acetylene or other fuel-gas cylinders, or near any other substance likely to cause or accelerate fire; or in an acetylene generator compartment.
What is the PSI of a full oxygen tank?
A full cylinder will read about 2000 psi (pounds per square inch). the gauge reaches the flow rate your doctor prescribed. the regulator. Secure oxygen cylinders in your vehicle so they do not roll or bump against other cylinders or objects.
What is the first thing to do before setting up TIG welding?
- Connect Torch. When using an air-cooled torch, use the adapter from your accessory package and plug the torch into the front of your machine. …
- Connect Remote Control. …
- Connect Work Clamp. …
- Select Polarity. …
- Prepare Tungsten. …
- Assemble Torch. …
- Install Tungsten. …
- Check and Connect Power.
Can you TIG weld without gas?
Simply put, NO, you can’t Tig weld without Gas! Gas is required to protect both the Tungsten Electrode and the weld pool from Oxygen. Most Tig Welder torches are also cooled by the gas, so not using gas would risk burning out the Torch. … You might also find my article Can you use the same Gas for Mig and Tig useful.
How do I start TIG welding?
- Use The Minimum Power. …
- The Angle Of The Torch. …
- Keep The Materials Clean. …
- Don’t Melt The Filler Rod Directly. …
- Wear Protective Gear. …
- Use The Correct Type Of Tungsten. …
- Working With Stainless Steel.
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).
Are all TIG torch consumables the same?
Torch Sizes TIG torches come in a number of set sizes: 9, 17, 18 & 26. … Each torch uses the same types of consumables, which each have their own sizes that fit inside when put together.
How do I know what 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 gas is best for TIG welding?
The normal gas for TIG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades.
How far should the tungsten extend out of the cup?
Tighten the torch down so just 1/16″ or less past the tapered portion is visible outside of the cup. This setup is a good way to get you in the ballpark and it will work for welding on flat butt joints and many other common weld joints.
How far should a TIG electrode stick out?
The theoretical formula – if the groove depth permits – the stick-out should measure 2 to 3 times the diameter of the electrode.
What is DC in welding?
What is DC Welding? Direct current is an electric current that has a constant polarity flow in a single direction. This current can be positive or negative. With DC welding, since the magnetic field and current of the arc are constant, stable arcs are produced.
What is welding machine inverter?
Inverter welder apply electric drive semiconductor power devices, it can precise control of the size of the current in the microsecond range. Control to improve the accuracy significantly improved precision welding and cutting, meet the needs of a variety of welding methods.
