Looks like a bargin if they are dry, 6013s or 7018s ?
You'll know when you see what they weld like.
Weldro were a premium brand before they were bought by Lincoln and their products absorbed into the Lincoln stable and then the name and the products disappeared. I don't recall when that was, 20 years ago?? But these rods must be quite old.
Depends how they've been kept.

looks good mate, id stick them in a warm place for a couple of days like a boiler room or stick them in the oven for an hour at 250 deg 
or stick them in the oven for an hour at 250 deg
100 C more like, but it will say on the packet. 250 C and you'll spoil them if they are 6013s.

all said never needed to heat 6013S normaly 7018s low hydrogens
Is there a name on them
Basically I made them. I think we were Welding Rods, or WR Electrodes or maybe Lincoln WeldRo part of Lincoln Norweld around the late 80s. I think we went ALL Lincoln around 88/90 and they closed the plant in 97.
We changed the names from WRX21, WRX30 etc to Omnia 21 and Omnia 30 etc. I used to get phone calls "whats your equivalent to WRX21" ......I would explain but often as not it fell on deaf ears.
I started in 77 and the company name changed with monotonous regularity.

are they a reddish colour?
If so they are WRX453 and were our alternative to Vodex. Originally WRX45 but we managed to improve the mechanical properties, namely sub zero impact strength, and the upgrades got the 3 added.
They are a sort of rutile basic so better properties than the normal 6013s

probably faded a bit with age
the red colour is iron oxide.......ie powdered rust
we used to make a WRX50 (later Omnia 50) which was exactly the same but blue. So we had to remove the iron oxide and add a blue dye (the same dye they use for denim jeans)
Believe it or not they welded slightly differently and we used to get customers who thought the blue were fantastic and the red were rubbish (and vice versa). There was a difference but not that much.
