Frankensteining two welders together

[Ducem Barr]

Hello dear internet folks!
I'm rigging a drive motor that's a bit oversized for the cheaper harbor freight machine. The circuit that drives the 24v DC motor produces only 22v that's not enough particularly when I add the gas magnetic valve. My all purpose power supply makes the motor happy with 0.65A and 25V , the gas valve pulls about 0.4A .
I'm having hard times uploading pictures .
It seems 24v AC coming in drives a big 220v contactor that switches the power to the main transformer, some of that 220v gets down to 24dc by a rectifier? 892h-1ch-c no7/nc5A. Wich drives the motor. The speed I'm guessing is changed by a triac jrf730 and potentiometer B470k there's a tiny IC I can't make out the numbers of and some capacitors and passives I don't think matter but IDK I'm a noob:/
Any help much appreciated! !!

Pictures? Schematics? Your description makes no sense without them.

Thank you, I got one picture up and now it tells me my "activities are spam like" :/
I guess I'll update once I get home on a computer

Nope - that's a relay.

A wider view of the board would help - better still a full schematic.

It's quite common to drive the wire feed motor using a simple triac circuit - often driven by the ubiquitous 555 timer device (IC) but sometimes the pulses are generated using a quad pack op-amp/comparator like the LM324.

If you're driving a larger wire feed motor the supply CURRENT has to be up to the job. Since the welder takes an AC input you could add your own power pack that was suitably rated - I'm sure there's space for it!
