[TheForge] mig welding

[terry l. ridder]

hello;

I use a millermatic 185. i have only used shield gas. my friend, Paul,
runs dual shield all the time. he repairs bobcat skid loaders. he rents
them out and they come back severely abused.

Perhaps if i had more time to experiement i would try 0.035 dual
shield. I would have to experiement with it for a while to get the hang
of it.

the millermatic 185 has served me well. never had an issue with it.
