Tungsten Inert Gas(TIG)
How does a TIG welder work?
TIG stands for tungsten inert gas and is technically called gas tungsten arc welding (GTAW). The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. An inert gas, typically argon, protects and cools the tungsten and weld puddle. TIG welding is similar to oxy-acetylene welding in that you use a filler material for build-up or reinforcement.
In race car fabrication, we use TIG welding for aluminum and 4130 chrome-moly steel. If you are going to weld either of these materials, you need a quality TIG welder. Miller offers products to accommodate anyone — from a home hobbyist to an advanced user.
If you have ever welded with an oxy-acetylene torch, you can easily weld with a TIG machine. The TIG process uses an electric torch, and the welder hand feeds filler rod into the molten puddle.
The ability to soft start and soft stop the heat makes the TIG process different from other types of electric welding. Some people like the accelerator pedal to control the heat if they are working on a bench and others like fingertip remotes on the torch if they are working in out-of-position areas. The remote adjusts the heat while you are welding.
Watford (/ˈwɒtfərd/ ⓘ) is a town and borough in Hertfordshire, England, 15 mi (24 km) north-west of Central London, on the banks of the River Colne.
Initially a small market town, the Grand Junction Canal encouraged the construction of paper-making mills, print works, and breweries. While industry has declined in Watford, its location near London and transport links have attracted several companies to site their headquarters in the town. Cassiobury Park is a public park that was once the manor estate of the Earls of Essex.
The town developed next to the River Colne on land belonging to St Albans Abbey. In the 12th century, a charter was granted allowing a market, and the building of St Mary's Church began. The town grew partly due to travellers going to Berkhamsted Castle and the royal palace at Kings Langley. A mansion was built at Cassiobury in the 16th century. This was partly rebuilt in the 17th century and another country house was built at The Grove.

The Grand Junction Canal in 1798 and the London and Birmingham Railway in 1837 resulted in Watford's rapid growth, with paper-making mills such as John Dickinson at Croxley, influencing the development of printing in the town. Two brewers, Benskins and Sedgwicks, amalgamated and flourished in the town until their closure in the late 20th century. Hertfordshire County Council designates Watford to be a major sub-regional centre. Several head offices are based in Watford. International conferences and sporting events have also taken place in Watford, including the 2006 World Golf Championship, the 2013 Bilderberg Conference and the 2019 NATO summit which all took place at The Grove.[2]
Watford became an urban district under the Local Government Act 1894 and a municipal borough by grant of a charter in 1922. The borough, which had 102,246 inhabitants in the 2021 census (up from 90,301 inhabitants at the 2011 census, an increase of 13.23%), is separated from Greater London to the south by Three Rivers District. Watford Borough Council is the local authority with the Mayor of Watford as its head – one of only 18 directly elected mayors in England and Wales.
