TIG welding parameters in direct current (DC).
Filling material
Filling material can be wire or rods; metal strips cut from the same weld piece metal can be used, in that case the
filling material must always be well cleaned.
The composition of the weld material must not generate porosity; it must be selected according to the basic
material to be worked on.
If suitable material is used, with uniform movement, the seam must be smooth, no porosities and look good.
