While we're on the subject I'd like to ask you what you think of
Bernard guns.

I'm having a heck of a time keeping tips on my 400 amp Tweco style
gun when I'm in spray mode. I want a good gun but my supplier hasn't
even heard of Tregaskis but the do stock stuff for the Bernard. So
that leaves me with the Miller guns or Bernard.

I don't like them.
Unfortunately Miller's Parent company ITW recently merged Bernard with
Oxo.
Oxo is one of my all time favorite MIG gun companies.
They still make Miller's Roughneck guns.

ITW bought Tregaskiss last year, but they have a history of buying
companies and yet leaving them alone.

ITW owns 5 MIG gun companies, 4 TIG torch companies and 3 Plasma cutter
torch companies.

From that list go with Miller Roughneck.

Good. Thanks. I've been doing a lot of research. I want to get a
good gun since I've been doing more spray mode lately.

Well, I picked up this today:

Btw, how well does the ESAB 7100 Ultra work with a moderate amount of
rust? The plate I'm using for the baseplate is somewhat pitted as well as
rusted. The pits don't look to be deeper than .025" deep, but my 4 1/2"
angle grinder is taking a long time to work it down. Since I've never use
the Dual Shield wire before, I'm not sure how well it deals with rust.
Spending a moderate amount of time, I seem to be able to clear about 50%
bare metal. Getting 100% will be quite a bit longer.

7100 ultra can eat a small amount of rust with no problems.
Just get off all the loose rust and scale with a twisted wire cup brush
on your grinder.
