Setting up a suitcase wire feeder

[Agroshield]

Anyone have experience of using a voltage-sensing suitcase wire feeder connected to a CC (constant current) power source (an inverter stick welder)?

Does varying the current on the power source have the same effect as varying the voltage on a standard MIG welder?

How does wire feed speed interact with current setting?

I have seen VJOs of the Miller suitcases and they have charts inside with basic settings. Are these or similar charts from other makers available as pdfs or jpg?

Many thanks for advice.

Id love some information on this too, Can i power a suitcase from another Mig source/ Multi process machine one that isn't suitable for work outside for example.

MMA to spool gun conversion: is it possible without a mig plant

OK, so after being sadly disappointed by the Draper MMA to Spool gun converter, which is just basically an expensive gas solenoid, gas coupling, mig wire speed adjuster and aviation socket in a metal shroud that needs to be plugged into an existing Mig plant. How feasible would it be to put all...

A voltage sensing, or “across-the arc” wire feeder is very popular and very misunderstood, so let’s start from the beginning.

running a suitcase on CC is bloody horrible. Like stick welding on a constant voltage powersource.
Some Suitcases have a CC mode, which does run better, but it's not great in my experience.
