Help finding a vendor for this welding wire liner

Help finding a vendor for this welding wire liner

Help finding a vendor for this welding wire liner

(OP)
I have been unsuccessful trying to find a vendor for this welding wire liner. I know I can buy it from a welding supply shop like praxair but they only offer it with ends appropriate for installing it in a particular MIG gun.

Anyone know what this type of item is called? Maybe something like wire wound flexible conduit? I not sure what buzzword will get me results.

Thanks in advance

RE: Help finding a vendor for this welding wire liner

Spiral wound liner or spiral wound conduit might work

RE: Help finding a vendor for this welding wire liner

But, what company's machine did it come from?

RE: Help finding a vendor for this welding wire liner

I think the term for that is conduit liner.

Google returned a lot of suppliers, but you haven't give a make of your machine.

Good hunting.

Also do a Google search for Bowden cable.

You are judged not by what you know, but by what you can do.

Thanks for the replies so far.

The one in my photo is from a hand held Miller MIG torch. We are putting it on a machine we are designing.

RE: Help finding a vendor for this welding wire liner

Is it actually a spiral wound conduit or is it just a ordinary spring wound with closed coils?
The photo looks a lot like a spring, but it could just have a big burr from cutting hiding the interlocking parts. If it is just a wound spring, they are easy to find or have made. You call it a "liner", so it may not be interlocking, its primary function may be controlling bend radii, hence a spring.

It is not interlocking like flex conduit used in the electrical industry. It is made from elliptical cross section spring steel.

I only called it a liner as that's what welders call them. A more generic term would be conduit. It is used to guide welding filler wire to the torch tip.

RE: Help finding a vendor for this welding wire liner

Fundamentally it's just a spring.

I'd think any spring winding company could make it.

RE: Help finding a vendor for this welding wire liner

your local supply shop should also have this on a roll (100m or similar).
so you can cut it to length and crimp your own connections/connectors onto the ends.

RE: Help finding a vendor for this welding wire liner

Called spring guides; drtempleman.com is one manufacturer of smaller sizes.

TenPenny,

That's exactly what I was after. Thanks a bunch.

RE: Help finding a vendor for this welding wire liner

Praxair markets a reduced friction liner called Ultraliner. It consists of a series of guide wheels oriented at different angles inside of the liner tube throughout the length. We have used it for robotic, semi-auto as well as manual welding machines.
