    Hi all, i have had a sealey supermig 150 for a while and decided it was due an upgrade so i ordered a euro torch and solenoid.

    the torch was easy to wire and works. The problem i have now is the wiring for the solenoid i have wired the earth to the earth and wired one cable to the neutral but where do i pick up the 230v to open the value when i trigger the switch on the torch???

    i appreciate all advise

    Not sure if this helps.
    You have made the top "X" neutral connection so just need the lower "X" connection. Check with a meter that it does switch !
    Make sure your "mains" wires in the wire spool side are better secured and protected and use some sleeving where it goes through to the electrical side.
    And welcome BTW :hug:

    i think i have made the top X connection as it seems all the neutrals connect together, the lower x connection is the one i am having trouble with im not sure which cable the FS1 is? if that cable is meant to be a switched 230v i have an issue as it is connected to a permanent live

    Think there should be one blue wire going to the power selector switch then five sleeved wires going from the switch to the main transformer and then the remaining wire on the power selector should be the "live" input it from pcb but can't tell from your pics maybe a white wire in your pics ?

    the selector switch only has one blue cable going to it on one side and then 5 on the other side of it, no others are connected to the selector switch

    my main power feed 'live' into the welder is connected into the connector block i was wondering if this was correct

    So it looks like they switch the neutral !
    So looking back at the diagram I posted, if you reverse on that diagram the live and neutral then that should match what you have. Therefore you need to connect the live side of the gas valve to a live point on the in coming mains and have the neutral feed from say the blue wire that feeds the power selector and that should give you switching when the gun trigger is pulled (use a meter to check for correct switching)

    And thanks for posting back cos you are never sure if mains voltage is involved if someone has fried themselves.....

    I have a Sealey 180 supermig kind of back up thingy and have a spare euro torch and was going to convert the Sealey with (if I ever see it again covid vunerable etc) But might as well learn Klingon than electrics. Is there an easy to follow diagram I can follow to convert the machine?
