I've spent hours reading through the newsgroup and have found lots of
great information. However one issue I have found many conflicting posts
about is the practicality of using 100% argon for mig welding regular steel.
I've read posts that stated is works great to posts that said absolutely
The reason I ask is because I have a free unlimited source of 100% argon
and a new Millermatic 175. Right now the only use I have in store for it is
welding mild steel and I just want to know the advantages/disadvantages of
using 100% argon rather than 100% CO2 or 75% Argon/25% CO2.
I ran some practice beads and did a few butt joints on 1" square tubing
for practice with the 100% argon and it seems to work just fine. However
I'm a beginner so what might look fine to me may not be acceptable.
Thanks for any information.
