Power source only mate... They do make one with an integrated feeder but as I already had my suitcase feeder going unloved since my ranger died, I figured go for the power source only.

I had a chance to run a few more beads with this machine yesterday before switching over to running a spool gun job off the might side. It lays a hot weld and doesn't seem to care that I've got it running on the end of 80m of 4mm2 sea off a 6kw Lister diesel... The v/a curve (slope) is adjustable which is interesting and makes for quite an adjustable arc.
Moved onto the aluminium job, 3mm outside corners. Settled on 20.5v, pulse percentage of 35% either side of that and 35% duty cycle on a 75Hz pulse (I think)... Seemed to get some acceptable results with those settings. Outside corners and Ali mig aren't exactly the best joint/process relationship, especially for a rookie like myself with a new machine.
I've got some heavy fillet welds to do next on some 6-8mm, will see how I can get the settings dialled in for that.
So far, happy with the machine for the cost.

You set the voltage, with the P.op parameter set to 'off' you get that voltage and the pulse is disabled - set that P.op parameter to a value and you get that value as the percentage of the set voltage above and below the setpoint.
Example:
20v, P.op set to 20%, you'll pulse between 16-24v
It works the same way on CC mode except the P.op value now represents a percentage of the preset CC value as opposed to a CV value

In a traditional Pulse Mig the pulse Amperage can be 600-700A at peak for a millisecond. Does this do the same?

I would have to check that with a scope and a shunt to confirm...

I did not buy mine from allweld_supplies, as their cart was not accepting PayPal. I bought mine from the seller I showed in the above picture...

That looks very well constructed for the price

It's nice to pay Chinese money for better than Chinese build quality

Smashed out some outside corners on 3mm, my first time doing that position with mig, seemed to lay a flat weld that punched in well.
Just picked up a teflon liner so I can move back to an mb25 instead of the spool gun. Should get some hood time this weekend
Any further thoughts on the Paton? Especially interested in how it handles pulsed mig and stick electrode. If it works acceptably, it's a bargain as I'm looking at US$570 for the power supply and under US$1000 with the 4 roll feeder, plus duty and some additional bump on the shipping.

I haven't put many hours on it, but I did do a little pulse aluminium job with it a while back.
What I will say, don't buy a vdi and expect to power an external feeder, the vdi omits the 24v auxiliary drive PCB. You need a psi model to power the feeder.
Thanks for the heads-up on that useful bit of info. Since I hadn't seen anything specific in their manuals explicitly mentioning the extra board on the vdi, I assumed that it simply had the power connector accross the board on all the pro series power supplies since it seems like they all have MIG settings available.

The vdi has all the settings there but the connector on the rear is wired as a 2pole instead of a 4 pole. It's still a 4 pole CB connector, but it just has the contact closure wiring for the mig wire hot/cold control.
The psi manual shows the 24-28v on pins 1&2, the vdi manual omits the wiring details for the connector.
