CEA Sureweld 126

[keith19]

Recently bought one of these old buzz boxes at a decent price, and it works fine after chasing out the spiders and cleaning up the inside.
Only 125A, runs fine from a 13A socket, runs 2.5 mm rods okay, even goes down to a 1.6 mm very nicely. (Used to get grief with 1.6 mm on the SIP).
Haven't tried it with a 3.2 mm yet, but it should manage the occasional one. It's not likely to be used much, just for when something a bit too heavy for the mig comes along. (I used to have a SIP buzz box, but gave it away...)

The spec plate is still readable, and I think I've managed to figure most of it out okay, except for the bottom line of figures, what do these stand for? The first letter is a capital 'I', not a 1, by the way.

O mm..........1.6....2.0..2.5....3.2...(Rod sizes)
I2A.............40.....55....80....110...(Welding Amperages)
Eh..............65.....25....18.......8...(Rods per hour, like duty cycle)
UoV............47.....47.....47.....50...(Open circuit voltages)
ALIMENTAZIONE 3-pin plug symbol (Needs an earthed supply)
I.240v........10.5...12.5..18.....23.5 (Not known?)

Is it not input current requirements?
I.e. at 80A it requires an 18A supply?
Seems very high but they normally exaggerate to cover the inrush current.

Thanks, Woz.
It had occurred to me it might be input amperage, but because it was so high I dismissed the thought, as it runs perfectly on a 13A plug.
I didn't even consider inrush current, as it's rarely bothered with, and only lasts a few milliseconds, far too quick to blow a 13A fuse on most hobby welders up to 150-160A. Wonder what mean figure they've used, maybe somewhere around x8?
But I can't think what else it could be, as it's obviously a 240V reading. So I'll go with that. Many thanks.
