    My SIP Migmate 130 'Turbo' is defunct - it just clicks when I press the trigger with no wire feed & there seems to be an internal flash!

    I've had it for around 25 years & have used it a lot. My question is; do I try & get it repaired or get a new one? If a new one, which is best for a hobbyist like me (who swears each weld is his last...;))?

    Have you taken the handset apart to see if it's just a problem with the switch? (It wouldn't explain the flash though, of course.)
    Personally I wouldn't pay to get such an old machine repaired but I would open it up to see if there's anything obvious. Apart from the circuit board they're not very complicated.

    I would suspect the two relays on the board, they have a hard life and burn out eventually. Can be a simple identify which type, if they are clear plastic you can usually tell by the scorch marks on the body. To test them you need to remove them from the board, otherwise you risk blowing some other component on the board if not careful.
    Just so you have an idea of what to look for inside the machine, here's mine from the an Oxford welder of the same vintage. Mine were Omron DPDT PCB Mount Non-Latching Relay, 12V dc Coil 5 A and a Omron SPDT PCB Mount Non-Latching Relay, 12V dc Coil 16 A, about £3.30 each. Yours would most likely be different. The circuit board should come out quite easily and will probably be covered in years of dust so could be done with a clean up anyway.

    You may also have damage to the board from grinding sparks or dust.
    I do agree that opening it up after 25 years is a good idea, the fact it's lasted that long entitles it to a cursory look, at best.

    I too had on old mig in the shed that I had used for years and years.
    Eventually it stopped working, the wire line needed a new one @ $125 bucks, and there was very limited functionality with the old girl....so I bit the bullet and bought a new "Inverter mig", infinite adjustment of all functions, ... I became an expert welder within 15 mins.
    For years I had misgivings about my capabilities, although having completed a 2 year course at the local tech on panel beating and vehicle refinishing, in the evenings.
    The new machine restored my confidence and my adventures of joining bits of metal to metal are now only merging into the annals of fame on the eastern seaboard of Australia ? well almost :rolleyes:
    Peter the welder :D

    my advice : go buy a new INVERTER MIG you will never regret it and think of me every time you use it? :p

    might even find a rats or a bird nest inside, possibly $ 10,000 in used notes from auntie rose, she liked to hide stuff ..... for another day?

    The Mig Welding Forum is a good shout. I replaced my 20+year old Mighty Mig with GYS SmartMig 162 and have never looked back. It makes welding a real pleasure.

    Thanks for all your comments & advice.

    I've had a cursory look inside & can't see anything, so have decided to buy a new welder, given that this one is 25 - 30 years old. The best reviews for a 'hobby' welder seem to be for the Clarkes, so I have gone for a 135TE from Machine Mart.

    I'll let you know how I get on :)

    I like my Clarke set. It’s basic, but it works well.
