spoolmate 200 trigger wont feed gas

[DDenny]

I have a brand new never used spoolmate 200 using it on a millermatic 251 with 100% argon for light aluminum work. Basically 14ga to 1/8" 2" square tubing to make light weight panels and small trailer repairs.
For some reason it will not feed the gas when I pull the trigger. I have it hooked up correctly, direct to the regulator. I have read through the owners manual and I cannot find cause or a cure for this. Has anyone out there experienced this. I dont see and adjustment for the tigger flow or anything at a loss.

thank you

Hooked from the machine to the regulator, correct? Then the spool gun plugs in the front of the welder. You don't have the spool gun hooked straight to the regulator, Right?...Bob

I'm sorta lost....
I thought a spoolmate 200 was the power source.
My 30-A hooks straight to the regulator, not to the machine. I don't know on the others.

There is a Spool-Mate 200 power source and a Spoolmate 200 gun. 2 different birds for sure...Bob

I assume he has a New Spoolmate 200 gun because he is hooking it up to a MM251..Bob

[aametalmaster]

Dang I have a new one on the wall maybe I better look at it..Bob

I hear ya.
The 30-A has a valve on the trigger.
Never took mine apart. Took some apart a hundred years ago at a regular job.

I have a 15a, 30a and Spoolmate 200. Guess I am thinking hookup for like my Spoolmate 185/3031 with a hose that goes to the machine first. I do remember now using a 30a on a MM252 and the line going to the regulator. My bad. Sorry...Bob

Manual says to hook it directly to the gas reg....(like a 30A)

but cannot tell from he parts diagram if it has a mechanical valve like my 30A or if it is a solenoid valve in the handle....

Here is the hookup chart

Correct it hooks up directly to the regulator. I thought maybe my regulator was faulty so I hooked back up to my mig and it works properly so regulator is good. I am just about to pull the hair out of my head have two weeks to get two panels built and this durn thing won't work. It's still in the 90 day warranty so have a call into miller about it as well. I don't see any adjustments or switches to adjust gas at the gun itself. The valve is in the trigger if it was an older gun I would take it apart but it is new.

Piece of lint in the gas hose....plugging the valve......??

Maybe disconnect and blow it out backward with compressed air............???????????????

Will give a try as soon as I get into the shop. Just blow air into barrel backwards correct?

Works the same way as the 30A. possibly too much gas pressure?

While working the trigger......

you might also remove the barrel.... to eliminate that as a possible bottleneck too...
