sip auto plus 180

[modelflyer]

Hi,to ALL i am new to this site and i need HELP off you
clever people out there.
I have a SIP AUTO PLUS 180 the problem i have is when trigger of gun
is pressed nothing happens so i bought a new euro tourch and the same
nothing happens.
so i have taken the side panel off and i have found a switch like thing
in a plastic see threw holder with contact points
so i have taken it out of its holder and touch the points together
and it works.
has anybody any idea what the cause is or if there is a way i can
bypass this switch with the contact points.
or where i can get a wire diagram.
any HELP PLEASE

what you have found is the relay it it should operate on 12 volts so you would need to check if the relay has burnt out and check for a 12volt suppy to the relay when the trigger is squeezed

THANKS for the quick reply.
can you please tell me how i can check the voltage
and what i should setting i should use on my multimeter.
THANKS this would be a GREAT HELP
THANKS AGAIN

you would need to set the meter to a dc voltage above 12 volts looking at the relay from the bottom there will be 2 soldered connetions by them selves its those 2 that recieve 12 volts when the trigger is squeezed DO NOT GET CONFUSED WHEN TESTING BECAUSE THE OPPOSITE TERMINALS WILL 240 VOLS AC
if you are in any doubt set the multimeter to 240 vols AC first and test if you dont get a reading of 240 then proceed to test for 12 volts dc

here is the wiring diagram you may also want to check the thermostat to make sure it can pass a current

 

[modelflyer]

there are 4 wires. the bottom 2 are black
and the 2 top wires 1 is blue and the other
is grey
but none are solderd
and all 4 are together on the relay
so i think it is the 2 black wires on the bottom i test.
is this correct PLEASE advise if i am right
THANKS for all your HELP

 

[the snooper]

trace the 2 wires back to the circuit board it looks like it will be those 2 the others will go off to the mains switch and the power control switch

A BIG THANKS THE SNOOPER FOR YOUR HELP
just hope that the relay is the problem
at least i can now go ahead and test
THANKS again

Quick answer is that it's only worth what someone will pay you for it.
Best bet is to fix it and list on Ebay. Clean it up first, show any accessories (gas regulator, welding mask etc.), few close-up photos etc.
The problem with trying to sell it on here is that SIP don't have a good reputation (though older stuff was undoubtedly better than recent offerings) so unless it's cheap you may be out of luck.
If you sell it as faulty then you may be lucky to get beer money for it (unless you're happy with that) - the big risk when buying is that the main transformer is burned out, which renders most sets beyond economical repair.
With it working, selling to a wider audience, 150A is a useful size... maybe £75 or more on a good day. Maybe
