    My No1 shed had 130 mtrs of 2.5 twin and earth supplying it for years, welder, circular saw, whatever, went up to 6mm, now 25mm three phase as I have moved all my clapped out machines down there, make of that what you will, sometimes in the winter the 8 foot tubes would go out when the circular saw kicked in,

    That’s a long way, especially on 110v, quick maths suggests you would need 16mm cable to keep the volt drop sensible :o

    would / could the extension lead be 240v with the transformer at the work end? would that help much, p.s. try it at home before going on site?

    That would be a big help, higher voltage in the cable and less current. But if it’s a building site may be frowned upon.

    Dont know, but decent sized leads, and a 32a outlet will be a start...

    The Deltic engine was built by Napier’s, my father worked in R & D there on it during the late ‘40s early ‘50s The loco was built by English Electric as you say.

    It didn’t work,even off 20m 240v cable,is this due to being 110 welder,years ago,I had a Migatronic 240v inverter,ran that fine off of 45m cable.

    the lower the voltage the higher of amperage cable needed on the supply . use 240 volt and a half decent size to the machine

    What size cable do you suggest? The 110 input cable on the welder is about 13mm and on a 32a plug.btw the supply socket is 65m away!

    presumably your plugging in to a 110 v site transformer. can you get the transformer near to the welder is it portable or on a site at a fixed spot

    No just an exterior 3 pin 240 socket,then the usual 3 Kva transformer ,if it helps,I can take the 10 kva out of the workshop,but I’d still be drawing off that piddly 3 pin .

    D Napier & son, Acton, London. Also built the Sabre aero engine used in the Tempest & Typhoon, another odd ‘X’ configuration. Taken over by English Electric during the war. It’s worth looking at Wiki & the Napier Power heritage trust for the history, quite interesting.

    Might have known my Grandad, he was there in the '40s, in the test houses mostly.
