I have a Millermatic 35 I use for general purpose welding on mild steel
usually 1/4 and less thick. Since buying it 30+ years ago, I have always
used .035, ER70S-6, and CO2 gas. I tried some Argon mixes years ago, but
IIRC, I didn't get enough penetration to suit me. I have never been real
happy with it's penetration qualities, but it's so much faster than stick.
The machine has never seemed quite smooth enough either. No matter where I
set the wire speed, it still seems a bit lacking.
Obviously things have changed a good bit over the years, and I'm revisiting
my choice of wire and gas. So I thought I would check the consensus of the
group.
Current recommendations friends and suppliers have been:
CO2 gas with ER70S-6 wire, but go with the .030 as opposed to .035.
CO2 or 25/75 gas with E71T-1M, or E71T-E7, .030.
No gas and E71T-GS, .030.
Would welcome any and all suggestions. All position would be nice, but I
need at least vertical down. Good penetration on hot rolled steel (without
pregrinding) would be a must. |

A Miller 35 is a great old machine.
I am surprised you say you can get penetration, since if you run that
machine balls-to-the-wall you can switch into spray mode (using C25
gas) and weld 1" plate.
I recommend using 0.035" ER70S-6, and C25 gas (75% Argon, 25% CO2) for
light gauge work (1/4" and below)
For heavier plate move up to 0.035" ER71T-1 (gas shielded flux core)
with a C25 gas shield.
For really big stuff over 1/2" thick, move up to 0.045" ER71T-1 with
the C25.
For work outdoors go to 0.035" or 0.045" ER71T-8 (self shielded flux
core) |

Well, like I said, I haven't experimented much with it. Just CO2, and the
..035, ER70S-6. I think the mix I tried before was either 25% Argon or 50/50,
and running this wire with CO2 only, and balls out to get the penetration,
you get some pretty big dill berries. I'll get a bottle of C25 this week for
sure. It sounds like gas alone might cure 90% of what's ailing me.

I would have never thought of anything bigger than 035 on a MM35, but will
keep it in mind. Can't imagine ever need to weld enough thick material to
justify a roll of it though. But I will try the 035 for sure.

I'm assuming gasless here. How is this for vertical up, or a wide gap? Would
another wire be better for all position?

What would you recommend for welding the thinnest possible sheet metal with
this machine?

Have you ever used E71T-E7 or 1M?

Thanks for taking the time Ernie, I really appreciate it. |

Jumping gaps is a balance of voltage to wire speed to travel speed.
If you do a classic triangle weave with gasless flux-core you can climb
fast and jump a moderate gap.
E71T-8 is all position, E70T-8 is flat only

0.030" is the thinest wire I would run in that machine, mainly due to
the gun and it's liner.
If you want to run 0.024" wire you would have to get a smaller gun
liner.

E71T-1M is a lincoln wire and I HATE it.
My favorite flux-ciore wires are made by ESAB, Dual-Shield and
Core-shield 8.

Coreshield 8, however, is not made in sizes smaller than 1/16".

Some of the dualshield stuff comes as small as .045". Most of the ESAB
wire, though, seems made for bigger machines.

Getting dual-shield wires in small amounts is hard.
Harris is the only company that sells these wires in small spools.
http://www.harrisproductsgroup.com/consumables/alloys.asp?id=12
What I usually do is buy a 30 lb spool of ESAB wire and spool it
myself, if I want to use it in my spoolgun.
You can buy ESAB 7100 Ultra, Dual-Shield wire in sizes down to 0.035".
7100 Ultra is the best Gas Shielded Flux Core wire I have ever used. |

I have the 175T and it doesn't show on my chart either. I think it's a good bet.
The machine can feed .035 wire and it can supply gas. What more do you need?

A beefier gun.
Dual shield beats the crap out of small guns.
It is why I have HUGE 40 amp guns on my Betamig 250 at home and the
Millermatic 300 at school.
Would it be ok to use .045" dual shield wire with a M25 gun on my
Millermatic 251?
In a few weeks I'm going to be putting together a power hammer out of 1/2"
H-beam and was planning on using .045" dual shield.
