Wireless TIG Welder Controller / Everlast TIG 210 EXT / Product Development

This video will describe a wireless TIG welder project I am working on. This will enable a TIG welder to control the welding amperage without using a foot pedal. The circuit uses a Scamp3 board and a LoRa radio module. A glove controller that decodes hand gestures will be shown.

Thank you. Interesting project. I've learned a great daeal from your videos and always look forward to them. Take care and try not to let those 💩 get you down :)

[@0033mer]

Thanks for the comment. Appreciate that.

[@johncatsoulis]

Another great video Ken. That's a really fascinating project. Well done.

[@0033mer]

Thanks John.

I very rarely comment on videos, but I unhid the comments section on YT especially so I could tell you that I really enjoyed this video; as I have many on your entire channel. I'm just starting my micro controller / maker journey, but am finding your videos a fascinating source of inspiration and ideas. One mans waste of time is another mans source of endless enjoyment. Please keep it up!
One question. How have you reverse engineered the pedal controls so you know which pin in that cable is for argon flow, which is for current etc. Do you come at it from the pedal, or the socket on the TIG welder box?
Thanks again

[@0033mer]

Thanks for the visit and comment ... Appreciate that.
The schematic for the footpedal and socket pinout was in the users manual for the welder.
In the video you can see 5 wires entering the control box. Two activate the gas flow with a relay closure.
The other three is for connecting to a 10K pot with 5 volts across it, which feeds 0 to 5 volts into the welder for amperage control. I am using a digital pot for that function. The pre/post gas flow times and maximum amperage is entered into welder itself. For complete setup info, check other YT videos on the Everlast TIG welder.

Great video. It's nice to see real world applications for microcontrollers . I am an industrial electrician and getting started with arm controllers

[@0033mer]

Thanks for the visit. I have a few videos on ARM microcontrollers.

[@ShellacScrubber]

Excellent stuff Ken and always good to see Forth at work in a useful and practical application.

[@0033mer]

Thanks 👍

I appreciate all your videos. Your experience is valuable. Thank you very much for sharing it with us. I wish you well with this project and look forward to whatever you choose to share with us.

Not sure what you're using for the control, but I once bought some Force Sensing Resistors to build tig torch controller but then I found somebody with a similar idea called the TIgbutton. I assume they're using an FSR, but I never bought one to find out how it was built.

[@0033mer]

I know someone who uses the Tigbutton. He likes it after getting used to the sensitivity. I was asked to come with an amperage controller not using the torch hand, and wireless. You just plug the control box into the welder and put on the glove. The glove uses optics and magnetics to decode hand "gestures" so no pressure is involved. I am also looking for other applications.

A beautiful project... in engineering and in heart! Bravo! Two suggestions... 1) For DIYers that want to weld aluminum, but don't have a true welder... There are aluminum brazing sticks that work with a simple brazing torch. These are the torches that screw onto the top of a handheld gas cylinder. The type that plumbers use to solder up copper pipe, with maybe two exceptions...a) I think "MAP" gas is needed to get a little more heat and b) MAP gas requires a little different torch head type. You will have to do your own research, because I have not welded in this manner, hands-on. I have watched the process, in person, and it is very much like soldering electronics. It is much less expensive to buy into than an electric welder. Maybe another viewer can give us more details. 2) I suggest also creating "training wheels" that would clamp onto the TIG torch head. They would set the welding distance and steady the tip. Maybe metal ball bearings would do for the wheels? HTH. Cheers.

[@0033mer]

Yes, there are other ways to weld aluminum. I have also used Ox/acetylene and aluminum brazing rods. I also use my TIG welder restoring vintage automobiles, cutting out rust and welding in patch panels. Thanks for the visit.

Great and versatile project!

Awesome Project......

[@0033mer]

Thank you

[@arturo2551]

Really interested in this one as I’m a welder myself, was there ever a second part to this video?

[@0033mer]

I sold the Intellectual Property of the smart glove that simulates a footpedal to a welding school. They are working together with a welding manufacturer for product development. I was going to to market the product myself and target handicapped welders, but a school would be a better fit where one on one training is available.

[@arturo2551]

@ thanks for replying. Man this is the closest I’ve gotten to figuring out a wireless foot pedal. Just barely out of reach

[@romancharak3675]

I don' t understand how a functioning project can be a "waste of time" , Ken? But maybe I'm Old School too.
