7018 electrodes are designed to be low hydrogen electrodes.
But if they are left out in the atmosphere for too long, they are no longer low hydrogen rods.
But that doesn't mean they are no good.
You can still use 7018 that have not been kept in an oven for anything you would weld with another rod like a 6013 or 7014.
Of course they weld better fresh out of the box or oven.
Once piece of advice I tell students for Stick welding overhead with 7018 is to set the machine hot enough that the rod will not stick even when you hold a tight arc....then hold a tight arc.
For dual shield flux core, polarity, voltage and wire speed settings, and stick out make the difference.
Jody sits down with JD Brewer, owner operator of Apex Welding. Hear answers to questions about his welding career, being self employed, and advice he would give anyone getting started in a welding career.
JD ordered a cart for his shop that included bottom drawer and foot pedal holder. In this video, we use a torch switch at high amperage for tack welding, then we compare straight welding current to pulse TIG.
And.... we experimented with pulse settings using silicon bronze rod and lay wire techn...
