Unitec S-165

admin

I'm rooting through some old stuff I came across some of pops welding rods - wrapped in newspaper 1989 or older = that's 25 years old.I've got flux coated braze,  6013, 7018, 7014, 308 Would you believe that the 7018 has the nicest flux coating - hard and intact.The 7014 is soft and powdery - but I'll try to dry it out and see if it hardens, maybe try it on some non critical projects.There is what I consider a lot of it.The braze flux is completely gone maybe good with external fluxI've got one  labelled Unitec S-165      3/32"I can't find any reference to what that is, some maintenance rod from an out of business firm ?amperage, polarity, prep and usage  ?

Reply:Stainless tends to run at lower current than equivalent steel rods. Figure 50 - 65A for 3/32" rod.Most types of stainless are non-magnetic, though, so further testing is indicated. Can you do a spark test? If you are not familiar with the term, a Google search will find plenty of examples. All you need is a bench grinder.JohnA few weldersA lot of hammersA whole lot of C-clamps
