A friend bought a MVP about a month ago with spool gun and cart. We hooked it up and ran .030, 035 and 035 Aluminum on 230v & 50 amp breaker. We put DC tongs on the ground cable and we could only get 151 amps output. that's what I based my post on. I don't think there is an issue with the machine.. Not exactly sure why we couldn't get to the 200 amp output.

Stickout and movement and a few other thing will regulate voltage and amperage draw, Why you could only get the 151 amps on clamp on meter may be purely technique at the gun....

Na, Ive been at this awhile. We did vary the stick out a little but we were using real world welding techniques. Im not sure why we got what we got. I'm guessing it's all the machine had. Spec sheet also says Rated @ 150 amp output.

BUT that is 30% duty cycle... look at the spec 250 amp at 15% get away from charts on page 10 and look at graphs of page 11 and 12...

In the beginning we decided to put the tongs on because the new MVP machine didn't seem to have the snort of his regular 230v welder when set at 200 amps. ( bought MVP for 115V/230v portabillity ) That's how we discovered the discrepency. He's taking it to his LWS to have it re-tested.

I would do the same.
I like testing machines with an amp meter, backs up what I tell students when I set a machine and tell them it's correct (mig, stick and tig).
That way they see what the arc is supposed to look like - helps them when they set the machine.

Thursday I had a kid supposed to be at 150 amps with 7018.
His weld showed a little cold to me.
I tried it and told him he's about 140 - he protested.
We put meter on, got 141 amps.
Dialed up to correct amps and he was like "hey, this is better"

Respectfully, that is misleading.
Although they provided a rating at 150 Amps 30% duty cycle, the max is still 210 amps at 15% duty cycle.

Those numbers are normally at 40ｰc or 104ｰf and will be better as the ambient temp decreases.

Good call !!!!

Ummmm....

Don't think Hobart would put this out for whole world to see if there was not a bit of truth to it....

Here’s a link to a related thread.

Can I tell you I love me new Hobart 210MVP welder
https://www.tractorbynet.com/forums/showthread.php?t=405596

I’m very happy with mine. Most jobs get done on 120 with flu core but when I plug into 220 for the bigger stuff, it has worked like a champ.

The Spoolrunner 100 spoolgun just got here and I have to pick up a bottle of argon to test it on some aluminum repairs coming up.

I see there is a spoolgun for the Hobart 210mvp and 190 thats half the price of the spoolrunner 100. Anyone have any experience with it?
I still havent bought the 210mvp, I keep going back and forth on that and a multiprocess welder.
