Hello Ladies and Gentlemen..
Recently I purchased a wireless foot pedal control for a welder which wasn't as wireless as I would have liked. Apparently I have to plug the wireless remote to a 120V AC to 15V DC adapter. Which means another extension chord and other unnecessary hassle. So I though I would stuff my own AC to DC power supply into the welder chassis and eliminate the external one that came with the unit. Seams easy enough but not for someone like me. My electrical knowledge is limited to 2 wires and 12V automotive circuits.
So in any case the welder operates magically with either 240 or 120V AC. It is a Lincoln Square wave 200 for anyone interested. The AC to DC adapter that comes with the welder is rated at 100 to 240V input and 15 VDC output. So I found a board mounted AC to DC adapter with what I believe to be similar ratings CUI inc VSK-S15-15U T. Specs and circuit diagrams are in the attached PDF.
Unfortunately this unit seams to require additional capacitors and MOVs and other stuff that I could hook up as shown but I found many different variations of these parts and don't know what to order. For example what voltage capacitors, and what type. So I'm wondering if its all necessary and there is an optional EMC recommended circuit is that also shown in this application. The Welder does operate with a high frequency arc that occasionally trips my GFIC circuit breakers.
If all this is necessary, can any one recommend components by part number and a source to get them. Or another adapter that has this stuff already buit in.
My other option is to solder two wires to the plug terminals on the unit that came with the welder and tie wrap it inside some where. Not what I like to do.
Any help would be appreciated.
Thank You
John
