Hello,

Few days ago i rescued from being thrown very old spot Hughes MCW550 DC Microcircuit Welder.

For reference it's looks like this:


Here i found manual over there:

It's basically looks terrible but i hope i will make it working.

On the back there are 3 fuses, there are missing (they were smashed) so i will have to replace them but i don't know witch values to use.

Does anyone have same model, and could share this information.

I'm also confused because power plug is UK, but on back label is stated 110V. As fare i know in UK they have 230V, so it's kind strange, maybe someone change voltage setting inside and then change plug.

In my lab i have variable power supply, so i will test at 110V so i hope i will found witch voltage is this unit .


So right now main question is "what's the value of three fuses on the back". If anyone could share any information, schematic please share.

It's definitely worth of repairing.

Regards
