M-25 gun nozzles

[GilaSlim]

I have a welder with the Miller M-25 gun. Looking on CyberWeld at replacement parts for the M-25, I see there are five different nozzles:

.500 diameter, .125 recessed
.500 diameter, flush
.625 diameter, .125 recessed
.625 diameter, flush
.625 diameter, .125 stickout

My gun has the .500 diameter, .125 recessed.

So when and why would the other nozzles be used?

Thanks,
GS

For inside corner welding you may want a shorter nozzle so the tip sticks out more. For outside corner welding you may want the tip to be recessed or flush. Just some choices you have.
try http://www.htpweld.com Jeff may have a better price on tips and nozzles...Bob

Hey GS,
Bob Wright is correct and, in addition, sometimes you will get better results by changing from recessed to stk-out especially when using dual-shield. Many completely remove the nozzle when welding with flux-core. I use the .500 exclusively and have all three configurations since I simply turned back an xtra nozzle in the lathe to .125 stickout to make the 3rd. Try some differing methods with each to see if they help your needs..... Denny

The standard tip is the flush one. I use it for everything except spray transfer, when I would use the recessed tip nozzle.

Great info guys, thanks a bunch! I'm going to order some this week. HTP only lists the .625 flush unit and doesn't give a price.

Slim,

weldingsuppliesatIOC (eBay dealer) sells the nozzles, as does Welding Depot.

Cope, thanks for the pointers. IOC is a little cheaper than CyberWeld, but they only carry two of the five nozzles. Welding Depot is the place to go. They have all five, and are less than half the price of the other two places. But they charge for shipping...

Thanks!

Welding Depot is the place to go. They have all five, and are less than half the price of the other two places.

That's because Welding Depot doesn't sell genuine Miller parts, they sell "Miller Style" parts. Cyberweld is selling the real deal. Not saying they won't work, but that's why they're "less than half the price."
