Get the Results You Prefer
Hot Start
Regulates the starting current at arc initiation for stick or
TIG applications.
Set it to your preference to help overcome cold starts at the
beginning of a weld, restarting AWS E7018 or stainless stick
electrodes or to improve starting for tie-in welding on tack welds.
Turn it down for thin material or root welding on pipe. Turn it up
for thick material or general construction welding.
Variable Arc Control
Adds or reduces inductance (arc energy), particularly for short-cir-
cuit transfer mode. Arc Control increases or decreases the size and
frequency of arc droplet transfer.
Set it to your preference to help control spatter levels or electrode
stubbing as well as to improve weld toe wetting or to obtain a
uniform bead shape.
Turn it down to obtain a softer arc or turn it up for a stiffer, more
digging arc. For MIG, you can turn it up to aid with welding on
open gaps, out-of-position work or for use with 100% CO

or
75% Ar / 25% CO
