Welding Tips and Tricks

hi all,
Looking for help identifying some stuff I inherited.

Welcome!

I don't know, I think you're gonna have to give a bit more information if you expect to get any help, but what do I know?

I inherited a hand crank corn sheller once. Maybe I’ll trade you even up. What you got?

post some pics of it and of any labels.
i'm sure someone will know it.

that's what that dirt stuff looked like just before I invented it...

Thanks for the responses and sorry for lack of info I was having trouble getting the post to go through.

So what I have is a lincoln hi-freq k-799

Wondering about the torch that came with it mostly. What are the 4 hook ups coming off the end of the torch. And I read in the manual about needing a back feed capacitor I believe is what it was called.

Also would be trying to use this with a lincoln weldanpower 225

Old miller gas units used a twist lock plug like that for push button start instead of scratch start. Guessing you have a version of that. The torch and cables should all be standard. You just might need a new switch to match your welder.

Edit the three threaded connections make me think it’s a water cooled torch.

Yup.. The Lincoln high-freq box also has a 'water inlet' label on it. So it looks like a watercooled torch.

Bye, Arno.

That's right. So what you have there is the water cooled torch and a high frequency box, condition unknown. If that's all you have, you're missing the power source ( welding machine) and the water cooler. Will cost enough money, if you can find them, to set yourself up with a modern rig...

Can the hi freq box be used without a water cooled torch. Also I have the power source a weldanpower 225 gas welder

Your going to need to find the specs on your high freq box. It may require cooling from the water, or it may just be a internal solenoid that controls flow through the torch only. Either way you need more info about your high freq box. But note that a water cooled torch won’t last more than a few seconds without flow.

Take the cover off and have a look inside. If the water in just goes to water out via a solenoid valve it's ok to use without water provided you use an an air cooled torch. If the water in also goes to the internals for cooling then you must have a water cooler connected.

I'd imagine that there has to be more connections to that box. The water would need an in and out, as would the gas. Do a search for "lincoln high frequency module" ... you should find that system and how it's used.

Hey guys thanks for all the info. I have another question I have an air cooled weldcraft wp-17v torch I'm using until I figure out the hi freq box. My question is will the 17v torch accept the same parts as a regular 17 or does the V mean something special.

the torch should be the same as 17. The V just means it has the gas valve on it which allows it to be used on a lot of machines that don't have a electronic solenoid to control gas flow. And it should take all the parts as the straight 17 and some other torches .. I believe the 18 and 26 will also take the same parts, Jody has some great videos about the torches and also sells the parts in his store ... Weldmonger.

Just to add to what BillE.Dee mentioned, AFAIK you should be able to use a valve torch on any machine, whether it has a pedal or not. Just open the valve so that it is always open and control the gas with the pedal. If you don't have a pedal, you need to use the valve to turn the gas flow on/off.
