electrode and the metal for 30
seconds, the engine will return to idle.
What the numbers mean that are used to
identify a stick welding electrode:
Using E6010 for an example...
The “E” indicates Electrode because some
welding rods are not electrodes. The “60” in
6010 indicates the tensile strength of 60,000
psi.
The last two (2) digits indicate position and
polarity along with what type flux. See

CV (CONSTANT VOLTAGE) MODE -
USING A VOLTAGE SENSING

CV (Constant Voltage) Mode – commonly
referred to as - Wire Welding, MIG welding,
or Gas Metal Arc Welding (GMAW).
NOTE
If a longer welding lead is desired,
optional 25 and 50 ft. lead segments may
be purchased from Vanair

Manufacturing, Inc. for a maximum lead
length of 100 ft.
