18826AED-BB93-4626-9AA9-C89282FE9F6C.jpeg I’d recommend some light reading. Hey fellow dude, I downloaded the book you recommended. Haven't really read through it just yet as it seems the more retired I am the busier I apparently get. LOL. Thanks for the recommendation [emoji106]. Sent from my SM-S...

So this is a bit random but it's not that easy to achieve what you want as the foot pedals / thumb wheels / buttons etc are using components that handle a few milliamps to signal a control board on inverter welders controlling the output - your welder appears to require a mechanical lever to be mov...

As a side note if you didn't want to use a foot pedal in this build have you heard about or seen a tig button? I have no clue if it would be easier or harder to get wired up to your machine but more options are usually nice so I figured I'd mention it. Sent from my S60 using Tapatalk Thanks dude. I...

Thanks. I appreciate the info. I'll call them 1st thing in the morning.... depending on what time zone they're in. LOL

Would it be possible to use a potentiometer in line with the tig torches power supply to control your arc? Sent from my SM-S727VL using Tapatalk i have to ask why? all tig power supplies have power control anyway. a Rheostat of that sort of amps is usually big and usually not exactly accurate for u...

I didn’t mean don’t do it. I just mean that’s the reason there’s not a lot of info on that type of conversion. I know. It sucks. I've literally (possibly literally lol) looked just about everywhere on the internet and there is just nothing on this. I'm amazed people haven't done this sort of thing ...

My advise is get proficient at scratch start and save up for a good used machine or a new inverter. I already have a mig, a tig, and a stick welder. I want to do this just to see if I can. It's a hobby. I'm retired and am trying to stay busy so I don't just die. Sent from my SM-S727VL using Tapatalk

https://www.weldingsuppliesfromioc.com/miller-maxstar-161-stl-tig-and-stick-welder-907710 Here’s a 160 amp machine with accessories for about the same money as adding controls to your existing machine. This is why it’s so uncommon to do what your asking about. You get more usable amps, better contr...

Doesn't it depend on the welder? If your running lift arc or scratch start I can see a rheostat being necessary, but if it's a TIG welder with a remote input then is usually just a pot. I know my Lincoln 355 uses a 10K pot, but I think Millers may use different ohm rating. Then you just have to fig...

Would you happen to have a link to one possibly?

I appreciate your input Minnesotadave, thanks. DC+does work pretty ok doesn't it? Like you just said though, it ain't super pretty. LOL. It does melt pieces together. Probably sometimes alittle too together. LOL. Have a nice night dude.

Hey Minnesota dave, would you have any idea how to retro fit a rheostat in place of the lever slide for amperage. I know it sounds like I'm asking a lot. It's because I am asking a lot LOL. This machine is just my toy. I have a good machine that's all DC. I have learned to DC+ aluminum rather decent...

LOL. Yea I know. That's why I want to integrate a foot pedal somehow. Any ideas?

Sent from my SM-S727VL using Tapatalk

I can already scratch start tig with this machine. As you can see in the pic I can go from DC+ to DC- to AC high to AC low with relative ease. I'm getting a high frequency box so I will be able to tig aluminum on AC. The only problem is unless you have someone else with you to run the amperage up an...

Thanks for letting me know how you did it. I do many things for hobbies and not really concerned about the price to much. I'm pretty good at finding deals on equipment that I might need. Would you be able to give a list of materials you used plz?

Sent from my SM-S727VL using Tapatalk

Let me rephrase a bit. This is a dedicated stick machine. No high frequency, not an inverter, but is AC/DC selectable. There is a high and low on the AC side and goes to 230amps. The DC side goes to 140 amps. The only other control on the machine is the on/off switch and the power cord. This is why ...

Is it possible for you to adapt a foot pedal to a scratch start tig setup?

Sent from my SM-S727VL using Tapatalk

Thanks for the info. I just like to do projects to stay busy and to challenge myself. If I can do it, then great. If not, no big. It's only $50 lost. LOL

Does anyone know how or has someone actually successfully converted a DC only welding machine into a selectable AC/DC welding machine?
