half-life

[Guido]

Hello everyone,

I address to those who have experience with mig/mag welding as I would like to know which is the optimal distance between the tip of the wire and the piece to be soldered, obviously mediating between the various machine settings.

If I get off the piece, say 20 mm, can I still handle the welding?? or is the gas dispersed?

Thank you.

depends on the parameters of the machine. to get away you must increase the gas flow and it is not said that with your nozzle can do it.

the distance between the tip of the wire and the piece to be soldered I would say that it is almost zero since you have contact to trigger the electric arc. the distance from the nozzle to the piece depends on the speed of advancement of the wire and the current, as well as the conditions of the material to be soldered, thicknesses, cyanfrines, full penetration, aesthetic cord and the position itself of welding.

are parameters that basically depend on the practice of a good professional welder. You can do tests. However normally the distance from the nozzle to the soldering piece is about a centimeter in the most abundant conditions.

I don't think there are universal parameters.
