Welding affects my microwave and trips breakers in house.

[paramud]

My welder makes the inside of my house blow breakers.
By breakers in the house, it is the ones in the plug.

The welder is on its own 50amp breaker to the main pannel (220v). I dont understand how it is affecting the other stuff on the main panel. The main panel is 200amp.

Anyone else experience this?

Will a sub panel solve this?

That picture is not a breaker. It is a GFCI plug.

What kind of welder are you using. A TIG with high frequency sometimes does not play well with GFCI's although I don't know why.

That is a UK device notice the plug configuration , not even a GFCI because of the 25 ma rating. The UK uses 32A ring circuits, hence the fuses in the attachment plugs.


Edit: But the OP's post is somewhat confusing because of the comments about the fuse in the plug blowing & 200A panel, 220V is not a US voltage either...

I have had a similar problem with my TIG popping a totally different breaker as well, I moved the appliance that was plugged in and problem solved. Good luck moving Her appliances!

I am using mig and it did it. No HF tig at all.

I will try to clarify.

200amp main panel outside.

The welder is on a 50amp breaker (uses both legs so 240/220)

The microwave (on its own 110/120) breaker is affected when I weld and those GFCI pop.


Yes, I am incorrect in saying that other breakers pop, because it is just the GFCI popping.

How old are the gfis? Older units were prone to tripping due to noise on shared neutrals

They are 9-10 years old.

Please clarify where you are located. I'm confused on that point. You keep saying 220, you show a device that appears to be British standard, then you talk about a 110 volt microwave?

Are the connections on the GFCI outlet clean and tight? I had a similar problem in my kitchen when I would run my electric oven. Inspected all the outlets and tightened the loose common connection on the GFCI outlet, solved the problem, but found 8 other nasty issues. Ended up pulling a permit and bringing an electrictian in to go through the whole house, pricy but worth the piece of mind that I'm not going to let the smoke out when I use the microwave.
