Spool Gun AL Settings…..Spray Transfer?

[BaitMaster]

I got a spool gun for my Lincoln Powermig 211i as me and a couple buddies are planning on building a couple AL plate boats…..

Anyway, testing out my new spoolgun last night, the “Magnum 100SG” meant for my welder as per Lincoln, and I was having some issues with the settings……

I was doing everything as per the book as far as DCEP, Pure Argon, cleaning, stainless brushing, etc.

I was using 5356 0.035 wire.

I was having an issue getting the “spray transfer” right. I couldn’t get spray transfer except for at the highest recommended setting which was for 3/16, even when I was testing on some thinner sheet metal.

The sheet metal it was doing the “globular transfer”.

Anyway, I don’t understand it. Help appreciated.

it wont spray until you are way up in the voltage, typically for thicker materials, so if you are trying to do spray on sheet metal its going to be cranked up, relatively

i would run some test fillet welds on coupon's of whatever material it is your welding and break them, check for penetration, go with the settings that give you good penetration and is controllable

Ok, so to make it spray, crank the voltage? Or the wire feed?

Can you turn down spray settings for thinner material? Or should it be doing short circuit or globular for thinner material?

short circuit for thinner stuff, but if you can control it in spray on the thinner material go for it. Your best bet is to just do a couple test coupons and see, those charts are a very rough suggestion to say the least, so dont put to much stock in them.

to spray normally you crank the voltage......but wire speed needs to go with it, you cant crank the one without turning the other up, they kind of go hand in hand, to much voltage with to little wire speed and it will burn back into the tip, especially in spray

Ok.

Ya I did some coupons and they were solid. It’s a lot more finicky in the settings it seems like to get it right, but once it works it’s lightning fast vs TIG.

My TIG does nicer work though, even with me operating the controls….

oh yea, not as nice but lightning fast comparatively , but you sure wouldn't want to tig a whole boat!

Would you mind sharing info about material thickness and machine settings?

I have the same spool gun and a Lincoln 180C so I’m guessing my settings would be very similar to yours. I have in no way explored the range of things that could be done with this setup.

@Tecnico does yours display in volts and in per min? Or is it just a number or letter?

@BaitMaster It’s numbers and letters, I’m guessing yours is volts & IPM just to make it more interesting………?

i believe if you check your manual it will have what letter/number correspond to what voltage and ipm
