Are these 15kg rolls Hood?
Wish I had built my feeder to take bigger rolls now - 'I'll always be able to get whatever wire I need in 5kg' - famous last words
My R-Tech can only take the mid sized rolls but nearly all the Mig welding I do is Alu and with the spool gun so it was of no concern to me.
Things may change with the EWM though. If I can get to grips with it then I may use it for stainless as well and it can take 300mm rolls.
Is it single phase Hood?
