Even if you don't have an on-board welder, it's good practice to carry some welding rod. There are many sizes and types, but our two favorites are 6011 or 7018 in a 3/32-inch size. Welding rod classification is standardized as follows:
First two or three digits: Tensile strength of electrode (60,000psi, 70,000psi, etc.);Third digit: Position of welding (1=all positions; 2=horizontal and flat; 3=flat only);Fourth digit: Welding Current (1=AC/DC Reverse or Straight; 2=AC/DC Straight; 3=AC/DC Straight or Reversed; 4=AC/DC Reversed; 5=DC Reversed; 6=AC/DC Reversed; 7=AC/DC Reversed; 8=AC or Reversed.
