What Torch

[Tom Orrow L]

What i'm seeing is this -

To get welding current to the torch you'll need to connect a stick welding unit to the HF unit through the "Power In" & "Work In" using dinze plug cables, another earth cable then goes from your HF unit to your work piece. The torch is connected via a 3/8BSP nut to the gas connection on the right hand side of the HF unit, the power would then come form the bolt lug connecter next to the gas connection.. you'd then need that torch to have the XLR plug on it to the connect to the remote plug receptacle. As far as I know, if you got that set up done you'd be away.

It'd need to be a two piece torch with a separate gas and power line.

Do you know if this hf box actually has a contactor inside or not? Some (my Miller hf-251 for example) do not come with them... Hf start is great, but snapping out to break the arc isn't all that nice... I added a contactor to get what I wanted out of my unit.

 

[Screwdriver]

Here's how it was hooked up when I used it.

I may have those leads somewhere but had you not been in such a rush, you would understand they are not going to be found any time soon.

That's exactly how ive got it worked out, just need to sort the torch now

Thanks Screwdriver, I had to get to hospital and see to my brother, he was diagnosed with Tuberculosis yesterday, kids were still at school, he should have picked em up and his Mrs was on a school trip, in France. It was a little hectic. And this all happened when I'd left home to come n see you

Just speaking to Parweld, they've confirmed that they do the cable lug type TIG torches. The part number for the torch you need is WP17-12-2-S31 or WP26-12-2-S31, I've had the Technical Director of Parweld look at the machine for you and he says that torch will fit your machine directly.

Would just need the cable lug aperture size.

 

[HughF]

Ever thought of a career in sales Tom good to know they still do lug and hose type torches.

Top man, It's 13 mm

Don't know about that one hugh

I'm not sure about that Hugh

It will need to be water cooled Parm... I might be able to scrape together a torch switch to clip on it. You'll see me using a very similar hf box with a torch switch in my DC tig video I posted a week or so ago. Link somewhere in the brew room.

Basically, hit the button to get some pre-flow, bring the tungsten in close, hit the button again, arc starts. Let go of button to extinguish arc.

Ok I'm gonna take you up on the offer of the torch if it still stands

 

[HughF]

It sure does. I'm vey far away from home all this week so it will be next week I'm afraid. PM me your address and I'll get it sent off.

I'm looking forward to seeing it all hooked up parm
Be lovely if you get her singing down a chunk of Alu.

Don't get too excited Sir, you haven't seen my welding

When I first started playing about with hf boxes and rectifiers about 15 years ago, I was using a oil cooled machine as the power source, I could not get good results with aluminium at all until I wired in what is described in the boc literature as a stabiliser box. No idea what's inside it as I haven't had the top off, but it's about the size of a drain cover and about 6 inches thick in a large metal box.

Possibly a large reactor?

I've done some homework on these, it's essentially a large coil with heavy gauge copper wire wound round a metal coil. I've seen articles were people have made THIER own using microwave transformers, also seen some basic ones made of old transforms and the like.

A full wave rectifier is on my plans, have you any pointers ?

Ps ive seen the work of the American chap that was on the forum a while back, he seems to know what he's doing

 

[Parm]

Many thanks to HughF, torch and a few other bits arrived his morning. I now have a Parweld W18 water cooled torch about 4m long. Now there is no turning back on the TIG project
