Eagle eyes lol on that relay - but yeah it’s facing the wrong way
- Thread starter bigkev75
- Start date
So the two nipples are facing each other - less travel - quicker reaction I suppose
I’d still have a Clarke over a sipSold for £291 !?
I'm in the wrong game .... so I need SIPs to modify.

Got to say I was gobsmacked at the price. I wouldn't have been too disappointed at the listing price to be honest- it would have covered what I paid out. I made contact with the buyer straight away and told him it went for too much and I would take £235 including postage and I'll refund the difference. I'm also sending a new torch instead of the old one. Second time I've done similar which sounds crazy but I honestly don't think it was worth more and I'd like him to be happy with it at a fair price. I think he'll be happy with it (because it really isn't like a normal SIP anymore and I'd say it is now at least as good as an equivalent Clarke) and I'll be happy with the £220.
Now just got the Topmig 150 to sell. That's had exactly the same mods done but because of size and weight it would be nearer £60 to post so think I'll wait till travel and pickup is easier.
I've been studying the pics of that relay and I still can't see the contact problem so must be looking at it wrong somehow. Great that Kev has got it going with Eddie's help.

The PCB-mounted relay is shown clearly in photo number 3 of post #71. There are two contact leafs or flat springs. The sheet metal of the lower one is thick, it does not move. The upper one is thinner and springy, it moves downwards when pushed by the white plastic plunger, operated by the armature of the relay.
On the thick leaf there is a contact shaped like a truncated conical cylinder. It is probably brass, maybe gold plated or gold flashed. It is riveted to the leaf and is pointing upwards. The flat contact surface is burnt and pitted, could do with a touch-up with a diamond file.
The contact on the thin moving leaf is not as tall, and has a domed head. It is also pointing upwards. It should be pointing downwards, to make contact face-to-face with the lower one. Instead, the lower one has been making contact with the rivet head at the back of that upper contact. The rivet face has not been shaped and polished for use as a contact, which is probably why the lower contact has burned so badly. The relay was assembled with the moving upper leaf back-to-front. It cannot be fixed, but still works. I'm just being pedantic.

I didn't click on that pic cos I hadn't even noticed there was the relay in it. I've been looking at the ones of the relay with the plastic cover on and wondering how you could see what's inside- X-ray eyes :-) Now it's clear thank you.
A pretty rare problem I would have thought and certainly not one I would have noticed even if I'd actually looked at the pic.
Pedantry is good but not something in my psyche I'm afraid. Probably one of the reasons I never made it as an electronic engineer.

No not at all buddy - good work by John , done two sips now with this mod but not with the pwm controller - be interesting to see how it’s done without the sip board - and make them more reliable
Maybe lockdown is creating something of a used MIG acquisition frenzy..?
As there's some very mediocre gear making strong money, for example:

Any one know if a spool gun could be retro fitted to work on the autoplus 130 sip I have one it has two dense 15 connectors and another din think that’s what’s it’s called. The spool gun has no wire speed control it is this one.the conector looks like it would plug into a port like this one in the picture

Hi Eddi.
ive got this relay to replace the one on my pcb only problem is it has 8 pins and the one on the pcb has 6 pins will it work?
Yes , was when I collected a welder from someone , they had the topmig with the spool gun on it , sort not much help - bet if you search the forum it’s been done buddy
That new relay is a good choice, and as Hutcho said, it will do the job.
At one end are two pins for the operating coil, and it is a 12v coil, as required by the circuit on the PCB.
To switch the main welding transformer on you only need On/Off functionality, known as Normally Open (NO) contacts. That would be two pins, but on this relay the contacts are doubled-up, moving together to share a higher current, so there are 4 pins. The moving pair are pins 11 and 21, and when the relay coil pulls in, those contacts touch pins 14 and 24.
That is a total of 6 pins. This relay may not exactly fit your board, so you might have to file the existing holes, or drill them out a bit to get a good seating of the relay. Small wire links may be needed to get the PCB tracks to link correctly with the 6 pins.
The extra 2 pins on this relay are 12 and 22. With the relay at rest, they are On, i.e. Normally Closed ( NC ). For this application, you do not need them. You could cut those 2 pins off, or drill large clearance holes in the PCB so the relay can seat with them still present ( as long as those holes do not cut through any existing tracks ).

Hey Eddie
I have the stuff from john to do the wire feed mod and I also have two relays one 240v and one 12v I haven’t a clue how I wire them I know they have 8 pins also what’s that yellow pull out tab for on the bottom ?
thanks Bigkev
