That's the MSDS for it, it says
AWS A5.1: E7016 H8

Thanks for that. The AWS classification tells you all you need to know about electrodes and filler rods & wire. all welders should familiarise themselves with the classifications.

This thread started about ray burn and protection.

Those of you who yearn for the good old days should have a look at this video clip. How would you like to work like these guys, No doubt a 60 hour week for $3.

Note well the quantity of personal protective equipment. One guy has a liberty cap and another a felt hat.

Here is a short video on electrode classifications. The narrator is a yank with an awful voice.

Forge welding was becoming a lost art for a while, seems to be making a come back with the knife building craze.
Pretty cool video, I like watching all the big saw mill videos their scary as hell.

In my experience, a cellulose coated rod will do that.
Don.

Thanks Don. Now that rings a definite bell. It was a long time ago but I reckon I recall that. Cheers

Austarc 11 | Cellulose | Arc Welding Electrodes | Filler Metals | WIA

Cellulose rods, like the linked E6011 are suitable for AC current. Most machines are DC these days.
The characteristics are harsh, hence why the old timers would call them 'fire sticks'. Greater Heat Affected Zone (HAZ) where the metal structure will be compromised, and be most likely to fail.
I believe they also have a higher diffused Hydrogen content in the weld deposit, meaning more defects as a result of hydrogen cracking/cold cracking.

They are an all position rod used in pipe welding or were in my day

Mainly used for the root run and 6013 were used to fill the rest if you had good access

What's the difference between GP and 16TC?

I have some 6013 GP rods ATM but am looking to try 6011 for AC and 7016 or 7018.

Should I bother with the 6011? Pretty much all of the stuff I will be welding will be prepped - the worst will be mill scale.
