Super ultra 205 power loss

Hey there, I hope someone can help me, I'm new at this.
I have a Superultra 205 multi function. I was stick welding in my shop, when a neighbour came by, I shut the power off to visit, for about 10 minutes, when he left, I went back to my machine, and it wouldn't turn back on. It won't weld, or cut, no power at all. I unplugged my unit, and plugged my old welder in, and it worked fine, so I know it is not before the plug in the wall. I wasn't welding anything very heavy, nor was it a long weld, only a couple hinges. The machine didn't make any noises, there was no smoke, nothing. I have no idea what could be wrong, ANY help would be greatly appreciated, thanks. Pat

Do you have any power at all?? LED readout , fan running. If not the likely problem is the red power switch on the unit has a problem.
If it turns on and you get gas flow an HF spark then the issue is likely a mosfet.
Cheers

Give tech support a call on Monday for instructions on testing the unit. The switch, etc. They'll get you fixed up.

No power at all, no lights, no fan, nothing. Is changing the switch difficult? Is it a part you stock? I can probably book a day off work, and head to Burlington, if you may be able to fix it while I'm there. I'm right in the middle of a project, and can't do anything until it's fixed. I'll try to call your office tomorrow, thanks for the speedy reply.

start at the end first did you check the plug first . i had a wire come loose once in the plug on of my welders once

The switch is easy to replace. Check the plug of course first.

Just checked the plug. All wires are connected, still nothing.

Can you check the voltage on both the line side and the load side of the switch ?

rivets

if it has a fuse try a new fuse . the fuse can look good but be bad . had a darn generator once that didn't work pulled the fuse looked ok should have checked it with a ohm meter , spent all day messing with and then put in a new fuse and it worked lol man did i feel stupid

I'm not sure if I should take it apart without someone on the phone walking me through it, I really don't want to do any damage to it. As far as checking the load, I do have a multimeter, but am not sure how to do it. As I said earlier, when I plugged my old welder in, it worked fine, so I know there is power to the plug. I'm wondering if there is a fuse in it, and where I would find it? Thanks

should be a fuse on the outside is it a super ultra or power ultra should have fuse i hope some were

Call in for support tomorrow. I'd tell you how to remove the cover and check it, but better to have an Everlast employee "on the phone" rather users on the forum telling you what to do. Get Duncan on the line or bring it in. Or call our tech support.

That makes sense Mike, I just don't want to waste anyone's time if I can help it, this forum is great, to help me with the obvious. I'll call Duncan tomorrow, I'm sure he can figure it out. If I need to, I can bring it in maybe Tuesday if he's not too busy.

It's a super ultra 205, I will go look now for a fuse, but if it's not on the outside, I think I'll wait until tomorrow when I can get a tech on the phone. Thanks for your input.

Found the problem, it was the switch, one side was bad. Duncan is sending me a new one, should be here in a couple days. Thanks everyone for your input. It's always nice to have other's experiences to draw from, also good to know there is support for any other concerns in the future.

see that happens when you buy stuff made in china , hahahahaha lol ,,, that's cool it was just the switch

Glad that's all it was. It is easy to replace compared to a bad MOSFET :)

Rod, there's not a lot not made there now days. And Duncan sells a lot of those units (he made a Canadian version) and they work very well, no AC, but awesome for the price and size. Duncan flies over and inspects the unit as well. So made in China, inspected by Canada.

Ah nice to know... So many threads on the internet about problems, then you have a similar one, stumble across the thread, and they never came back to say what the fix was.
