I just got a a Japanese Hakko desolder gun that runs on 100v
I'm powering it with a 230 to 110v step-down rated at 200w. The Hakko takes 98w.
The step-down is pulsing - the led - when I press the vac button on the Hakko it is also pulsing.
Is the step down borked?

Did you try the Hakko on another step down?

Did it do that pulsing before with other stuff attached?

What amps is the Hakko and step down rated for?

May be that the step down is not actually rated for 200w if its a cheap Chinesium generically branded one. What brand is it?

I always stick with Airlink step downs these days, yeah they are expensive but they will probably outlast me!

I have ordered a new step down.
I’ve used the oils on a cab before and I was getting some pulsing on the Montrose image. It’s a cheapo one rated 200w, but probably isn’t…

You can't get to the fuse without taking it apart (I presume)
It pulses on an American cab too, but works - this is probably why the screen was pulsing slightly. I'm thinking it is fuc*ed.

What is stopping me just using a Japanese monitor step down transformer on my Hakko? I'm pretty sure I have a few spare lying around...

Yup, just tried it on my Nintendo cocktail cab. Unhooked the monitor inside and plugged in the Hakko. Started heating straight away and the pump was working continuously.

Probably didn't even need to buy a step-down...

Yeh I have a step down that I try to use with a heat gun and heat gun blows fuse ..

American heat gun .
Crappy fuses .

I have a psu original taito needs attention .. spikes badly I have got to fit new caps on it asap!

And another cab
With neo geo mvs it’s fine on first power on ,

But with capcom cps2 I get pulsing for 30mins ..

Then goes away after warm up .. again I’m assuming caps.

But I think one hardware allows for the pulsing not to interfere with the vídeo .

True. I'm on the lookout for a 'vintage' degausser. I got one of those green sticks of death, which was DOA. I took it apart to fix, and it is abysmal quality. The mains wiring is about a dozen aluminium strands. The button wiring even thinner. It basically just disintegrated at the mere sight of a soldering iron. The only good thing about it was the pleasure I got from slam dunking the crap into the bin.
