Dc motor off ac power

I have an old engine driven welder I just got running decent and now I'm wondering about the feasibility of putting this wire feeder on it for occasional sheet metal work. My welder has a 110v outlet at 50 hz. This wire feeder I believe has a DC motor, is there a simple way to run it off the welder?

You would have to convert the AC to DC by using a power inverter. However, an inverter that size could end up costing quite a bit.

It would help to know the DC power requirements for the wire feed, or the make and model #.

Does the wire feed welder run off belt drive or is it plug in? (guess I should've asked that question first)

If the motor is speed adjustable, and all I have seen are adjustable to allow for thicknesses and changes in amps, it would not be reasonable. If (and only if there are no (zero) electronics in the motor drive, and if the motor is a universal motor with brushes, you could put a variable voltage supply into the motor. If it runs (and many brushed motors accept AC or DC) it might work. If it just hums, or there are electronics in the circuit, nope. Jim
 
Are you sure its 50 Hz? The only engine-driven Hobart I ever dealt with put out DC on its 110 outlet. (It was, admittedly, much older than yours.) If you only ran portable power tools off that outlet, you wouldn't know it was DC since those tools usually have brush-type universal motors than will run on AC or DC.
 
You can easily make 110 dcv using 4 diodes, build a bridge rectifier. Google bridge rectiflow.
You might have to, add a large capacitor.
