Small stuff today

Damaged corners in a deep area of a mold cavity





All welded up and ready to be EDM'D back to original

Yeah, but how are you on trailer hitches?



Sorry, couldn't resist. I've seen some of your previous posts on what you do and am very impressed. Wow! I've never seen welding utilizing a microscope before.

When EDM first came out we found the best thing we could do for customers was to teach them to temper after EDM to prevent cracking !

I can weld a trailer hitch to a gnats ass with this welder

I'll supply the gnat if you supply the hitch!

how would that work for filling in some rust pits on an action?

If all of the rust was removed it wouldn't be tough at all but all the rust would have to be gone

You are obviously using some of the gnats we have in Northern Alberta. Those fawkers come from the factory with a chrome vanadium chassis, titanium wings and carbide drilling equipment. I've seen them pack off moose calves.

No bullshit ! ! ! ! ! he he he he he

This particular welding unit is designed to give a single high energy pulse at the desire of said craftsman with little to no heat into the surrounding areas of the work piece and is designed for very small intricate work....hence the microscope

.
It must have a fearsome small diameter tungsten rod to keep the arc radius of the weld that small. Or is there some other trick to that Ted ?

1/16 tungsten

No tricks.....that I'm aware of

I somehow assumed that less juice would require smaller diameter. What I know about electricity could be written on the back of an aspirin with a 4 inch paint brush. LOL


Just for giggles. How many amps is that ? Or the lack thereof ?

40% of 300 joules @ 5 micro seconds

Joules? LOL I never was any good at French. It sounds like more than a carpet spark and less than a Bic Lighter Ted.

I wonder what the best process to accomplish that would be?

Air grinder and a 1/16 round carbide burr

Cut it out to the white one at a time

Whole lot different than welding growser bars on Cat tracks like I've done several times.

How's the arc flash thru that microscope??

George

There is zero flash

The microscope is hard wired into the welder and auto darkens

A wise guy might have led into that with a long winded explanation about the advanced "rapid blinking" classes and seminars offered by the company that sells them Ted. LOL

I was waiting on a couple 3 or 4 forum standbys to chime in and tell me more about what I'm doing.

They might even explain the microscope

I think yah got em all beat this time. That setup is even too specialized and unique for the couch potato engineers to tackle.

But I'll bet you a box of beer, some of the internet tight-wads are going to be commenting in other forums about how they're going to build a MUCH BETTER one, using just 2 Coke bottle bottoms, a shoe box and 400 feet of grounding cable so the line lose will get the power down to the needed level. Actually, they will have worked out the line loss and it will be 101 feet 11 and 1/4 inches.
