What To Use

[hot head]

I have been given the unfortunate task of welding what seem's like miles of angle iron. I am building pesticide spray equipment for the shop that I work for . The material is 3" wide by either 1/4 or 1/2" thick. I have no idea the kind of steel it is or it's strength. I have to make beautifull welds and they have to have to hold 4-500 lb's . Oh and did I mention that it has to be done with an old ac/dc arc welder that's the size of a buick!! What sort of rod would you recommend that would give me strong and deep penetrating welds??/ I apppreciate all the help.

I would recommend using either a 6010 5p+++++ or a 6011 on ac.

hti ti with 6010 then go over with 7018 . 7018 has a nice finish when you get the heat right the slag with just fall off.

Prepare the joints properly and use either 6010 on DC or 6011 on AC or DC.

Just run 7018 on them, there isnt really any reason to run a root for this type of weld. I am not sure why you would need deep penetration for realitively low strength requirements. DCRP

I Would us 7018 DCRP in one pass
