TIG Welders

Filter


Welding is used across a wide range of industries, including aerospace, automotive, energy & construction. During this process, pieces are united or fused using heat and / or compression so that they form a continuous whole. Heat is usually generated by an arc flame created by the welding power... source. The fusing of the pieces can occur solely based on the heat produced by the arc, so that the welding pieces melt together.Read more

TIG Welders

Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW), is an arc welding process that produces the weld via a non consumable tungsten electrode. TIG welding must be carried out using a constant current power source (either DC or AC), which is essential for avoiding excessively high currents being drawn when the electrode is short circuited onto the workpiece surface. This could happen either deliberately during arc starting or inadvertently during welding. TIG welders are ideal for joining metals like stainless steel, aluminium, nickel & copper alloys, cobalt and titanium. These welders are used for producing spatter free weld seams.
Raptor Supplies offer a broad range of TIG welders from brands like American Weldquip, Hobart, Lincoln Electric, Miller Electric & Tweco. Miller Electric TIG welders come with a power source, an external water cooler with coolant, running gear, a water-cooled TIG torch, a TIG consumables kit, a working cable with a clamp, a flow gauge / regulator, a gas hose, and either a wired or wireless foot control. The lightweight design of these TIG welders offers portability for moving from one workstation to another. They also have digital meters for displaying actual voltage & current ratings and adaptive hot start for providing arc strikes without sticking. Lincoln Electric TIG welders are equipped with an AC Auto Balance feature that allows the unit to automatically adjust for the optimal mix of cleaning and penetration. The operator simply has to select polarity, process and desired amperage to begin welding. Choose from a wide range of TIG welders, available in one & three phase variants on Raptor Supplies.

Uses

The most important applications for TIG welders are pipeline and pipe welding. TIG welders are also used in the aviation & aerospace industries for welding particularly thin materials or special materials such as titanium. They are suitable for both manual and mechanised welding.

Features

  • These TIG welders use a non consumable tungsten electrode for producing an arc on the workpiece.
  • They have an adjustable AC Auto Balance feature which increases or decreases the cleaning action.
  • They also enable the TIG pulser to minimise material distortions caused by excessive heat output.

  • These 230V AC / DC TIG welders feature a unique, single knob control for quick and easy set-up & use.
  • They have a lightweight, inverter based design that includes foot control.

Working Mechanism

While using TIG welders, the required current is supplied via a tungsten electrode, which is temperature resistant and does not melt. This electrode emits an arc that heats up and liquifies the material. There is a nozzle for shielding gas around the electrode. This protects the heated material from chemical reactions with ambient air. Noble gases such as argon, helium or mixtures thereof are used for this purpose. The inert (i.e. non reactive) gases prevent chemical reactions with the liquid weld pool and the heated material. This ensures high quality weld seams. As the tungsten electrode does not melt, the filler material is fed in by hand or in mechansed form by an external wire feeder.

Standards and Approvals

We offer TIG welders that adhere to ISO 9001:2015, AWS and OSHA standards.

Frequently Asked Questions

What are the advantages of TIG welding?

Due to the low amperage required for this process, TIG welding is ideal for welding thin materials. The TIG weld process can be controlled, owing to the independent arc and filler metal applications. This allows the production of very high quality welds having an excellent appearance. In contrast to MIG and MMA welding, TIG welding does not produce spatter, so clean-up is minimal.

How to select the shielding gas?

Shielding gas is selected according to the material being welded. The following guidelines might help:
  • Argon - The most commonly used shielding gas, which can be used for welding a wide range of materials including steel, stainless steel, aluminium and titanium.
  • Argon & Hydrogen (2 to 5%) mixture - The addition of hydrogen to argon makes the gas slightly reducing, assisting the production of cleaner-looking welds without surface oxidation. As the arc is hotter and more constricted, it permits higher welding speeds. The disadvantages to using this mixture include the risk of hydrogen cracking in carbon steel and weld metal porosity in aluminium alloys.
  • Helium and helium / argon mixtures - Adding helium to argon raises the temperature of the arc. This promotes higher welding speeds and deeper weld penetration. The disadvantages of using helium or a helium / argon mixture are the high cost of gas and difficulty in starting the arc.

What should my shielding gas flow rate be set at?

Shielding gas coverage is very important during TIG welding and you need to make sure you have the correct settings on your bottle, so that you have clean welds and so that you don't finish up a bottle of Argon gas in a few hours. A good baseline to start your settings at is 15 to 20 cfh, and you can increase it if needed.

Why is my Tungsten getting consumed so quickly?

If you believe tungsten is getting consumed quicker than usual, the following problems might have occured:
  • inadequate gas flow
  • welder set to electrode positive
  • improper diameter tungsten for current
  • overheating tungsten
  • gas not shielding after the arc
  • the use of the wrong gas

How to know when to use AC and when to use DC TIG welders?

Steel, stainless and iron alloys are usually welded with DC and negative polarity. Aluminium and magnesium are welded with AC, and sometimes with a square wave AC current.

Which is better - TIG or MIG welding?

TIG welds are better for thin metals and small projects because they produce precise and clean welds. MIG welds work well for large projects with thick metals that need long & continuous runs.
