Anybody in need of a noise source from HP? 10MHz - 18GHz. NAWTS

https://www.ebay.com/itm/133473253993



An old model long out of calibration. Seems to have been pushed around a bit much and has a lot of scars and dents.
Is the connector still OK ?

You can also get some cheap yet very good MIG welders these days, which are easier to use on sheet metal (cars etc.)

Realistically $600 by the time you've got the gas bottle and other supplies, including various protective gear sorted.

Received a bit of low-cost network gear:

[attachimg=1]

Left switch is standard with 9V wall-wart, the right hand one is a PoE enabled one with a 48V power brick. Rightmost is a PoE splitter.

All of them use the very same size barrel connector, for 9V input, 48V input and 5-9-12V selectable output. WTF?

That’s a pretty big  :palm:. To be fair I wish they’d get rid of DC barrel jacks entirely. Horrid things.

Cisco have best answer. IEC on the switch and proprietary molex thing for PoE.

Been dere, dunnat, got the shirt full of pinhole burns already.  More like $300 when I did it ~15 years ago at Horror Fraught. ;)

I'm looking at this one as both a quick & dirty stick welder to get by with until my HFT MIG is back where it belongs, and as a future TIG power source for when I need to do fine work on SS/AL.

next thursday iám driving 500KM to :
1. sell car allumium winterwheels, to have money for TE
2. pickup lots of TE   ,spent immidiate ;-)
3. pickup a cheap cable lenght analizer or something.. guys sells it as a scope... for 25,- .. so lets see ;-)

excited allready :scared:

It is Aluminium.   :)
No idea, what allumium could be.  ;)

its very light weight ;-) very special.. only Kia .. :-DD

Made from onions...
They actually feel to be almost as thick as a coke can. A friend of mine once had an early Kia Sportage and the panels on it could be easily dented just by leaning on the wheel arches etc, very flimsy indeed, doors felt very light by comparison to mine, which close with a reassuring clunk.

I had a 1st generation Kia Sportage. A 1998. Yes, kinda cheaply built and a maintenance nightmare. But with the 4WD would go anywhere.
Sort of like a Korean version of a Land Rover.  :P :-DD

With my second car I used to climb over the bonnet so I could sit/stand on the roof. I got a much better view from up there.
What car was it then?

I should have noted that the body panels were aluminium, about 3mm thick. This one, like mine, also had a Perkins 4.1 diesel engine; it would pull the skin off custard, as well as a speedboat up a launch ramp without a driver in the cab :) That was a benefit of having 16 forward gears (and 4 reverse gears) in 3 boxes :) Steered like a Lazlar Lyricon spaceship, which worried oncoming cars on single track roads.

Fukkin' eBay... when I put this in my cart, it showed delivery before the end of the month; STILL pretty crappy for ANY form of Priority Shipping considering 500 miles, even WITH customs. Now it's showing "August 11th-Sept 14th"  :wtf:

Been dere, dunnat, got the shirt full of pinhole burns already.

I'm pretty sure half of my "bald spot" is from welding slag from my MIG landing on my head and permanently searing hair off...  :)

That's my story and I'm sticking to it!   :-DD

Edit:  The other half is from bashing my head into stuff...

*tzzzzzzlllllzzzzzzllllzzzzzt* :-/O

The novelty condom MMA welder in that video is DC only. Ya won't be welding Al with it.

Unless you're The Flash and can swap the Dinse connectors over fast enough.  :)

I've actually been musing over the purchase of a TIG setup recently, I have some possible uses for proper hot melt glue. Looking at what's around, the minimum "expensive enough that you won't regret buying it"/"expensive enough that you only buy it once" price point for a fully rig with a decent torch, gas, and starter set of consumables looks to be around the £1200 GBP point.

For some reason AllTest always indicates extended shipping dates, even for me. But they always beat the date by a significant amount.

Actually, it's PWM-switched DC with zero post-pass-element filtering at somewhere between 15-30KHz in most of these; I've used a similarly tiny ESAB (well, about the size of case of Bud) TIG power brick before, which was similarly PWM-regulated. Pretty sure very little reason you can't TIG anything you like with it provided you use the correct envelope gas.

Naaahhh... their business model is "cheapest possible shit for your SOHO". They will use the cheapest form of power they can get, period. If you mix up your 5.5x2.1mm coax-connector power bricks and crispy-fy something, not their problem... "KA-CHINNNG! Turnover."

Yeah... not sure if this is AllTest's estimate or fleaBay McNugger-juggling the numbers. Either way it pretty much sux if it doesn't arrive by the time I'm outta here.  :-\

Aluminium needs a positive electrode (DCEP) for ~30% of the time (to break down the oxide film) and DCEN for the rest of the time (to stop melting your tungsten) at something around 120Hz (10-200Hz). The current has to physically reverse, not merely be 'AC' in the sense of being DC that's switched on and off. It's a plasma, the physical electron/ion flow matters.

I think you have older tech in mind; pretty sure the newer stuff runs higher frequency because square wave.  ??? There's a difference between "best" and "can't". Worst case I can only TIG sheet/tube aluminum; I've done that with DC. :-//

bd139 is right on the money; IEC inlet is the way to go. But, then you need to do a more thorough validation of safety, because of the internal PSU, and the bottom feeder SoHo gear has no margin for such.

The Type 561B project is finally a wrap. The final outstanding issue fixed. The Type 3B3 Time Base plug-in had a bad ceramic capacitor which killed the sweep. All fixed. So it's now a complete and functional unit. I still have a Type 3A6 Vertical plug-in to fix and a Type 3A74 Vertical plug-in from the 561B parts unit that needs check out but those will go to the back of the repair cue for now. I wanted to concentrate on having the mainframe, vertical, and time base fully functional and that's been accomplished.  :-+

Note: That trace is actually pin point sharp. Damn camera phone.  :-//

...And I can get it for approx USD$57 delivered RIGHT NOW.

I've seen articles saying it's been available for as little as $38; what I've been able to find indicates those are all bait/switch ads with the leads offered separately at that price, while the welder itself is $70-90 depending on amperage/whether it has LED display. Personally, I like that it is offered separately from the leads; they are heavy and cost a lot in shipping, and are often something you already have or can source/make cheaper locally.

If I weren't moving, I'd probably have one on the way right now.

mnem
*tzzzt!* indeed.

Now it's USD$54 from China (Sold out til Aug 8th)  or USD$66 from US (In Stock). Daang...

If I hadn't just spent $600 on new glasses...  :palm:
