Anything new on foot pedal designs???

[jtybt]

Mark,
Does the 'new' Canada foot pedal look like the one pictured in the 'Accessories & Parts' section. It's just that I'm looking for as low a profile as possible. The one in SCC was what I was thinking about. It's the same design as the one on our ultrasonic cleaning table but probably bigger and heavier duty.

Also, is that link to the SCC/Ebay foot pedal for a Miller compatible with the 225 LX

http://cgi.ebay.com/350467901759#ht_1010wt_884

and can just connecting your connector do the trick?

..and here's a Hobart replacement foot pedal. Will this work with just the right connector

'Works with all Hobart welders that use a 10-pin remote connector.
Replaces Hobart model 409004A and 362668'

I believe someone already connected an SCC to an Everlast.

Hey Thanks! I just inquired about that same model. I'll post prices when I get them.

Ah, glad I could help

I tried rolling my own pot+switch foot pedal for a previous project; it's just not worth the effort, even at $150 for a commercial pedal. If I could have found a Casio pedal like this guy used, that would have been nice. http://www.mg42.us/viewtopic.php?f=10&t=7208&start=0

Oh, not I found one on eBay... http://cgi.ebay.com/330573831104 The nice thing about that is that it is already setup for a pot. It may not stand up to a shop environment; getting kicked, dropped, stomped, stuff dropped on it, etc.

Digi-Key has exactly 1 style of 47K pot in stock, but 55 different 50K pots.

Un freaking believable! I got one of those HF 130 TIG's. I never new it was a lift start. I did all of my initial TIG learning on that thing all the while trying to scratch start. I always liked it but it had it's drawbacks. I think I'll fool with it just to see how it works doing lift starts. Might even try that pedal Mod.

Thanks again.

I finally found the proper search string to use on eBay to get pedals that already have a pot; "volume pedal".
One would likely still have to change out the pot, but at least it is already setup for one, and adding a switch shouldn't be a big deal.

I saw someone post a custom made footpedal project on the internet somewhere, out of heavy aluminum scrap stock they had. They used an unusual method of translating the pedal motion to pot travel. It looked effective, and "reliable" / "bulletproof". I wish I could find the link.

[jtybt]

I like the double geared set-up to give the pedal travel more POT rotation. I placed a bid on that casio but someone else is bidding on it, too. Hope I'm not bidding against someone here. I will remove my bid if I am.

I just thought, my brother has a few electric guitars. He might have an old foot pedal that doesn't work and I can take it apart and try to figure out how to Mod it to work with the 225LX.

if you're looking for just the casing, smallbear sells them: http://www.smallbearelec.com/Detail.bok?no=548

Now that's a pretty nice looking pedal. Probably sturdy enuff for my set-up.

I did win the Casio so I'll have something to fiddle with and familiarize with the workings. I may very well try the shell and fit the stock components into it. I would like to get a better picture of the inside dimensions and gear set-up to see how much 'throw' the pedal would input to the POT.

Maybe we're on to something here.

The SSC foot pedal with 25' cable is a 50K (ohm) 2 watt potentiometer pedal ($125.90)..shipped to N. Cal for $138.55.

...and found this on Ebay...

Here's another pedal I found on eBay a while back... looks to be very compact too.
http://cgi.ebay.com/350469743375
It's still plastic, so it probably wouldn't stand up well to an abusive shop environment.

Just an off the top of my head guess is that it would not have 7 pins if it did not need that many; so it might have a switch also. The pot would have three wires, and a if it has a SPDT switch, that is three more... then one unused pin? It might also be highly price compressed and not have a regular pot that you could replace, but be like an ultra cheap computer joystick with linear pots integrated into the plastic assembly. -- at least it isn't much money to risk for anyone interested in finding out.

I sent a message to the seller a while back asking if s/he had more info, but s/he did not, and suggested that I check the mfgr website. I was not able to find any technical info about the pedal http://www.ramprodinc.com/p-344-vari...istorized.aspx other than that it is "transistorized". I haven't the faintest idea what they mean by "transistorized". Maybe it sends a PWM signal back rather than a voltage?

foot pedal I built for my Tig welder PM256

Very nice Tom, How about another pic of the electrical side.

[jtybt]

Yeah, That's nice. Shows a LOT of ingenuity and thinking out of the box.

I'm thinking hard on that ebay pedal for $99. I'm asking questions about it and will let y'all know how it turns out.

[acourtjester]

Her you go

[jtybt]

That is SOOOO great. You aught to patent it. Especially the use of the toothed belt. I have all those parts laying around.

[acourtjester]

If your are going to make one be sure to support the pot shaft.
I used a pot with a 2" shaft and a bushing made from UHMW plastic and welded up this bracket. The spring tention would be to great on the pot shaft with out a bushing.

have fun
tom

Ain't it neat the things you can do with a welder!!

I'm trimming down the case of the foot pedal and re-drilling the position of the pivot shaft for the pedal bracket. Next I'll try trimming down the length of the rack so I can trim off the bottom of the case. I think I can loose 1 1/2"- 2" off the overall height.

In the mean time, I got a Casio foot pedal for a musical inst like elec piano or guitar or something or other. One of the guys put up a mod someone else did to adapt it to the harbor freight 130 TIG... the post by Parkour and his link.

Internally it has a toothed lever that engages a gear that steps up to a larger gear that turns the POT. The pedal movement is short and turns, thru gearing, the POT 7/8 rotation. The Everlast POT turns 3/4 rotation so there's plenty of room to adjust for full movement. All I have to do is make a bracket to mount the toothed lever/foot pedal to pivot on and a bracket to hold the POT and one to hold the gear shaft. The only thing is the gears turn the Casio POT counter clockwise so I'll have to flip the Pot.






The neat thing, the gears are the same pattern as a sewing machine belt so I can do a mod like acourtjester did if need be.
