Here is a video demonstrating the use of 6010 and 6011 arc welding electrodes. Personally, I use more 6011 than any other electrode because it is very easy to use and gives good penetration and a strong weld even on poorly prepared steel. 7018 is better for welding high-carbon steel, but for me 6011 is where it's at for most welding of mild steel.
Possum living is all about living on our own terms, slowing down and kicking back and doing what we really want to be doing instead of burning ourselves out in the pursuit of what society tells us we should strive for. It is about finding easier and more interesting ways of providing what we really need, as an alternative to paying the high price in time, money and freedom that society extracts in exchange for servicing these needs; and about finding the strength to say no to those services we don't really need.
