The only way to tig is to have your ground clamp hooked to the positive side of the welding machine. The negative lead will go to the tig torch. If it is reversed you will find out very quickly when you strike an arc. Most metals will be welded using this Polarity (straight). Most Aluminum TIG welding is performed using A C current.

Properties of Bright Drawn Mild Steel?
Bright mild steel is an alloy. It is usually used to make hammer heads and shears, and it has a smooth, but tough surface.
What is the yield stress of a twisted bar as compared to an ordinary mild steel bar?
Tensile yield strength in a steel bar is the amount of pressure exerted before the bar begins to bend. Tensile steel is used for a variety of construction projects.
Why CO2 can not be used as shielding gas in GTAW?
CO2 is an oxygen compound or a non-inert gas,the purpose of a shielding gas is to shield the weld and the electrode from oxygen. argon, nitrogen and helium are the most common gases used for GTAW
What type welding current may be used with GTAW?
A C, with high frequency superimposed, when welding Aluminum. D C straight polarity on almost everything else.
What is mild steel used for?
for rc works
What rod should be used to weld mild steel to stainless steel?
309
Why is mild steel not used on pushchairs?
duev to its ductility
What metal is hard and is used the most?
mild steel.
What material used for galvanizing mild steel is?
Zinc
What materials are used in making rivets?
mild steel
Which is harder mild steel or copper?
Mild steel is harder than copper as it has a higher hardness level on the Mohs scale. Mild steel is commonly used in construction and manufacturing due to its durability and strength, while copper is known for its excellent electrical conductivity and malleability.
What is the purpose of a gas shield use with GTAW?
GTAW is commonly used to weld thin slections of stainless steel and non-ferrous metals luike aluminum, magnesium and copper alloys. The gas shield is never removed to prevent oxidation of its surface and contamination of the weld.
Why is mild steel used to make chains?
Because hard steel would be brittle and break.
Which stress is used during the tensile test of mild steel?
During a tensile test of mild steel, the bar is tested until it breaks. It measures how much stress the mild steel can take before it finally breaks under the pressure.
Is carbon steel the same as mild steel?
both of these are same In some places they are used interchangeabl low carbon steel has 0.05-0.15% carbon mild carbon steel has0.16-0.29% carbon http://www.metalsupplies.com/
