welder help wanted

[rustic]

The switch is a multi position switch, that sends power to various coils of the transformer. This then sets the overall available welding current.

The colours of these cables could be anything, so best to follow the motor wiring, or fan wiring back and work from there, as suggested.

There are various diagrams on the internet, including one for a sealy 180, looks similar BUT could be wired differently.

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

Does he like you, I mean, he don't want to kill someone at work, but your OK to knock off :lol:lol

Now theres a thought.



Um if you do pop off, can i have your T2

If that is a rotary switch then it would have an on/off position I'm guessing.If you have a multimeter and you set it on a resistance ohms range you should be able to work out which pair of wires belong to which.Touch the probes together when on resistance(if analogue then the needle will go hard over,if digital then it should read zero),then you will be able to see the circuit you are looking for.If you look at the two connected wires then look at the opposite positions on the switch then in off position there will be no reading between the opposite terminals then when in on position it should read zero.This should give you the pairs you need to connect to.Follow the wires from the internal side of the switch and you should be able to see which is positive and negative.Hope this may be of help.

Haha course you can... it needs welding though :lol :lol

Having had another look at the terminal connections,if it's like ones I've had dealings with then the pairings should be 1 and 2,3 and 4 etc,try with a multimeter to see if they are the pairs when in on and off positions.

Cheers matey.
Im gonna pinch the multimeter from work tomorrow and have a look.

most welders have one side of the primary windings tied to earth, as this is the same potential as neutral, you should be able to locate the neutral with your meter, but do not guess it could damage the welder if you get it wrong, Rick

 

[spautoparts]

Thanks for everyone's advice. Its now up and running

 

[spautoparts]

Tried it on some scrap. Its messy I know but I wanted to see if it worked

Result...:thumb2:thumb2:thumb2

Well done, as I have said before, we know about other things not just Terranos.


The guidance given, was cautionary, test, check and double check...
Steady wins the day.:thumb2

Other forums might have told you to wire it up, any way you want... switch on, then when it goes bang, will try and convince you it was faulty anyway.

Oh, this story line rings a bell, its how Ford Dealers used to service the Maverick:doh:doh I never found a good one during the three year warranty period.
Went in with one fault, came out with three.:doh

:lol

Good news about the welder, you will get a better weld with clean metal, looks like good penetration though.

 

[spautoparts]

This is why I pay the tenner.
Good knowledge is worth lots of money:thumb2

 

[solarman216]

I could be wrong, but looks like there is a fair amount of cable on the red drum, if so it will get hot and burn out on a welder always unwind fully, if it was unwound, accept my apologies, as my eyes aint what they used to be, Rick

Id love to learn how to weld

Pop down here for a day Zipps and I will teach you, Rick

 

[zippy656]

Thanks rick we may take u up on that.

Me and daughter, be in the summer

Thanks again rick.

Welcome any time mate as long as I am at home, just pm me a few days before, Rick

Yep will do

Its easier than you think. Its all in the preperation.
Buy a cheap welder and have a play. Once you get the settings right on your machine you soon get the hang of it.
