Converting to a euro fitting - are the wires up to it?

[Angusdog]

Okay, I have a Telwin 160A MIG which had a 'hard-wired' hose which I thought would be worth converting to a euro fitting.

This is the new fitting (cost next to nothing):

This is my welder's inner bits, showing the original cables from the hose running to the pos & neg connectors:

The issue I have is that the wires on the new fitting are tiny compared to the original. But thinking about it, the existing wires aren't that beefy all the way up the hose as they're much too thick, so they must 'slim down' to get into the hose.

New versus old wires:

Do you think it would be okay to run the thin new wires to the connectors, or are they much to lightweight to carry the current? If they are, the fitting is pretty much useless. However, I'm thinking this must be how it's supposed to work and that the wires that go up the hose must, by nature, be pretty slim.

Any ideas on the above?

Thanks,

Simon.

Those thin wires on the Euro fitting are connected to the triigger.

You just connect the thick live wire to the brass block, which should obviously be insulated from the chassis of the welder.

There doesn't appear to be a connection on the brass block, did you get some sort of cable clamp with the kit?

They look like they only operate a relay.

Follow the +ve cable into the other side of the welder and see what's in there.

Hmm, interesting. I just assumed the original thick wires went up the hose, but thinking about it now, I see they don't need to. I shall have a look at where the original wires go (which I should have done first, I guess) and see if I can work it out.

The new euro fitting just arrived as you see it in the photo.

I have a job to construct (a rotisserie for a mini shell) which I want to do before I strip down the welder in case it's out of action for a while.

Thanks for the replies so far - I didn't expect any so soon, but I guess it's Sunday evening there, whereas I'm supposed to be working as it's Monday am here

The black and red wires are your welding cables, you can swap them over for polarity change but don't connect those wires to them. As said they only operate a relay. The other side of the +ve cable goes to the transformer and the end you can see goes to your new brass euro block which is insulated by the plastic carrier. You'll probably see more of what you need to do when you remove the old torch and cable. You are missing a clamp.
