Anything new on foot pedal designs???

[jtybt]

My welding table is just always cluttered so I made a roll around table that slides under the other table and I use that 90% of the time. Since sitting at a 31" high table makes the foot pedal really awkward to use, I was wondering if you guys ever made a nice small, compact foot pedal. I always like the size of the foot pedals of some of the sewing machines since sewing machine tables (29")
are close to the height of my rolling table.

We have had the new style for a few months now.

Mark,

I see that in the 'Accessories' section, the foot pedal still uses the toothed thingy that turns the rheostat. That in itself requires a design with a high profile. The sewing machine design has a lever that turns downward pressure to horizontal rotating section of a 'wheel' that can easily incorporate either a tooth design on the outer ring or turn a different type of rheostat. It all can be incorporated in a 3" by 6" by 2" high base with a pedal that is only 2-3 inches high.


I think you could do wonders (and sell tons) with a design like that.

As it says, some items may vary in appearance, or something like that. Some of our product pages have been updated...but its the same one Canada has been using for a year now.

Do you have the particular values of the rheostat. Maybe I can modify one of my older sewing machine foot pedals to work on the TIG.

47k for the panel controlled units

my hope is to use the same pot and micro switch but come up with a different pedal to house them in and a different operating mechanism.

The object would be to get a pedal that is closer to the ground, maybe made of a bit heavier steel or aluminum and also to move the pivot point closer to the rear or at the rear of the pedal so the pedal is less of a rocker style.

If I get time this month I might make a new foot pedal for the Everlast.

I made one for a bead roller project and I'm pretty sure something similar could be done for the Everlast, although the function is a bit different.

Will post it as a project if it happens soon enough.

I'd like to know how it's done. Is there a wiring schematic that shows what wires to connect to what terminals on what switch/terminals or pot terminals etc???

take a look at your pedal and pin it out. There's a microswitch to activate the arc and the POT to vary the amps.

This is a pic of the sewing machine foot pedal



This is a pix of the actuator lever at rest. Notice the short green, forked lever that swings the rheostat lever. This changed vertical pedal movement to the horizontal.



This is a pic of the rheostat lever when the pedal is depressed.



You can see, with relatively little pedal movement, quite a large sweep of the rheostat lever is made.


Anybody got an ideas how to convert this to a TIG pedal? I got no idea what the rating of the rheostat is. It's the movement that may be of interest.

I hope someone at Everlast can come up with an adaption that will make such a small pedal design available.

You'd need to pretty much trash the pedal and use a 47 k pot and create a cradle that would slide onto the shaft for the arm to rid in. It looks as this is a multiple step, not a continously variable pedal.

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.

here is the pot you want http://www.mouser.com/_/?Keyword=785-53c150k&FS=True
have fun

Ahhh! $9... for a pot?

try digikey.. http://search.digikey.com/scripts/Dk...=potentiometer
select 50k, continuous rotation, click apply filters, then click view page (1).

One of these might work. There are 32 others.

OK thanks guys. I'll check into them. I remembered I have some aluminum diamond plate laying around. I'll check it out to see if it would work as a case.

I'm on my phone, so I didn't check the mouser link, but $9 is a fair price for a sealed 2w conductive plastic or mil-spec carbon pot, which is what you want for this type if service.

I had heard of mouser, but did not think they had the deep selection that digikey has.
Then I saw the $9 for the pot and was not impressed.
To be fair, digikey has $9+ 50k pots also.
So I looked at mouser for some other parts I regularly order from digikey, and lo, the price is appreciably less than at digikey

This is awesome
Acourtjester, thank you for linking to that pot.. it made me look at mouser again and found lower prices
I like this

When I had my electronics business, Digikey was my last resort for ordering parts. They always were higher on everything.
