rovercoupe Posted July 7, 2018 Report Share Posted July 7, 2018 Its a bit of a dark art really, there are alot of variables involved and even how old the steel is and who made it makes a difference. 2.5mm rods i think are 70-90 amps 3.2mm 80-130 amps 4mm 130-160 amps then you have to take in the following, the thickness of the steel, what type of weld you are doing, what type of steel, how hot the work is if its a multi pass weld and probably a ton of other things too! I was carp at welding untill I did a big job and burned alot of rods and then understood when people talk about the feel of how its welding and watching the pool. Im sure someone with more experience will chime in but thats about all I can give you really! Quote Link to comment Share on other sites More sharing options...

oldypigeonpopper Posted July 7, 2018 Report Share Posted July 7, 2018 hello, is that thick walled tube, ??, looking at what you have made before i am sure it will be ok, good luck Quote Link to comment Share on other sites More sharing options...
johnphilip Posted July 7, 2018 Author Report Share Posted July 7, 2018 Its 3 mm wall onto about 6 mm plate Quote Link to comment Share on other sites More sharing options...
oneshot1979 Posted July 7, 2018 Report Share Posted July 7, 2018 For 3mm wall tube onto 6mm plate I'd go with Oerlikon E7016 in 2.5mm. 75-80 amps. This is our preferred rod for 90% of our jobs at work. It's really forgiving The flux is like molten glass and you have to be doing something really wrong to get any inclusions.

johnphilip Posted July 7, 2018 Author Report Share Posted July 7, 2018 (edited) Oneshot thanks , i can't find that number E7016 Edited July 7, 2018 by johnphilip Quote Link to comment Share on other sites More sharing options...

Never done Tig , always wanted to try one. hello, i used a Co2 pub bottle but the argon cylinders do weld cleaner and aluminum, i have just a small light portable arc welder now to 160 amps, my first was oil cooled, first mig was a Cebora for home use but at work we had industrial mig welders, not the ones used today i am going back to the 1970s, let us know how goes with the new one Quote Link to comment Share on other sites More sharing options...
oneshot1979 Posted July 7, 2018 Report Share Posted July 7, 2018 They are a bit specialist but give a beautiful weld with virtually no manipulation needed to manage flux. 6013 will do the job yes but if you want a pretty set of railings then splash out in the 7016. If you can' find them locally let me know. I'm sure I can sort something out. Quote Link to comment Share on other sites More sharing options...
