[spautoparts]

I have acquired a siegen power mig 180. It needed a new power cable so I got one. Only problem is I dont know where the live and neutral connect to.
Anyone have a clue?

Inside

The two screws in the middle on the bottom bank are undone. I just need to know which one is live and which is neutral

Are the terminal marked A1 or A2 if not what?

 

[spautoparts]

Not labeled and no markings.
Would it kill the machine if it was the wrong way round?

 

[spautoparts]

Just removed the switch it has this label.

Look up the rotary switch part number on google. May help.

I can't find anything on the internet, but there are a few forums for that welder though.

In theory it shouldn't matter if the line and neutral are swapped over in most electrical appliances. BUT I don't know specifically about welders.

Earth is essential, and MUST NOT be wrongly connected.:doh

On welders, there might be some electrical interference suppression, which can connect to line and neutral, so this might be an issue, but both are normally and equally suppressed.

Any other device like, wire feed motors, might have additional switching and if mains powerered best switched in the live rather than the neutral.

If there are brown and blue wires connected to the other terminals of the switch, then this will help to determine the correct connection.

For example there must be an indicator light, or fan, or motor, work back from any blue or brown wires.


Hope this helps,

Rustic

I was thinking along those lines.
I'm going on the theory of matching it up to the wire colours on the opposite side of the switch.

Oh well. I have a 50/50 chance
whats the worst that could happen?

NOW
back to basics...
Why was the cable removed in the first place?
What is the history of it?

Is it likely that it was broken anyway, the cable removed for another project, or removed for safety

Either way, use an extension lead, switch on from a distance... a long way away, in an area if it smokes or worse it doesn't cause any other issues.

Make sure someone else is close by to you just in case.

Good luck

Cheers rustic.
the welder was given too me by the father in law. Its one he used in his garage and was working with no faults.
The cable was removed because it was damaged and he didn't want the other mechanics killing themselves with it. Health and safety and all that.
he bought a new one and gave me this

Ask him, he took it off

 

[spautoparts]

He can't remember:nenau

 

[zippy656]

Geting old.


I know how he feels

How many poles are there on the switch, what I mean, how many positions can the switch be in?

eg just on and off will be 2 positions.

 

[spautoparts]

7 positions from 0 to 6

Is there not a single power switch on the rear? Mine has the same rotary switch on the front but also a on/off toggle on the rear.
