TIG Tungsten Size question

Oct 31, 2004 4 Replies

What are the consequences of using tungstens that are larger than the minimum size? I commonly use 1/8" for most of my welding and was curious if I would see any noticable improvements from dropping down to 3/32 or even 1/6 when possible. As long as the area to be welded is clean, I don't see any arc stability problems.



Thanks in advance,



Bob


1/8" tungstens are more expensive and will tend to make the arc wander more at low amps. 3/32" is the most versatile tungsten size. It covers a comfort range from 20 ga to 1/4"

The smaller the tungsten the less amps you have to use so your workpiece won't heat up as bad. I use .040-.125 all the time. Iowa883

How come you can't use low amps with thick tungsten ?

It takes more amperage to get the same penetration. Which heats up your workpiece which is bad in my profession. I am a journeyman tool and diemaker an weld tool steel all the time and heating the block produces stress related problems. Iowa883
