6013 stick welding tips for anyone in welding school trying to move on to 6010 and 7018...or who wants to build something and only has an AC buzz box welder.
6013 rods are designed to weld on DC or AC and it doesnt really matter much which one you choose.
I like 6011 rods because:
6011 rods burn good on both AC and DC and both uphill and down
most small inverter welders will burn 6011 but not 6010
6011 electrodes are readily available at big box stores and places like tractor supply
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 r...
