Another question re my TIG welder. i have, thanks to kind folk on here,
sorted out a proper 60 amp single phase supply in my workshop. i have also
bought, from Farnells, some proper industrial 60 amp 3 pin 240 volt single
pahse plugs and sockets. One is a wall socket, plus 2 plugs, and one
trailing socket, the idea being to make up an extension lead if I need the
welder more than the supplied 15 foot lead length away from the wall
socket. The welder has a black rubber sheather 3 core cable on it, with an
ouytside diameter of about 16mm. the conductors, over the insulations are
about 6mm each. hefty stuff.... Where can I buy about another 20 foot of
this stuff please? Thanks. The cable sections of the likes of Farnells and
RS Components are bewilderingly complex and huge for the likes of myself!

You might find it difficult to buy less than a full drum,
but if it's possible at all, then I suspect your best chance
would be an electrical wholesaler. Some of them sell some
of the more expensive cable types by the metre, but 6mm
flex is probably too infrequently used to keep a drum in
stock for cutting up. 4mm flex (for 32A connectors) is more
commonly used (I think I have some 4mm PVC flex somewhere).
