This process used in combination with the inert gas welding covered.
Nowadays, the welder prefers to use argon gas so called Argon welding which similar with gas welding by using both hands,
one hand is holding the welding torch and another hand holds the wire.
In case of welding without welding wire, it will use the heat from arc melt 2 work pieces to completely connect
which called apply welding suitable for 0.5-2.5mm. work piece.
The welding process requires to use welding wire is called TIG filler welding.
The welding process requires to use welding wire is called TIG filler welding.
Thyristor welding machine able to supply both AC and DC power. And another type is inverter welding machine which has either Mosfet or IGBT
