. Weld and auxiliary power output stops if
generator overheats or engine speed is
too low.
1 Engine Switch
On models with recoil-start, use switch to
open ignition circuit, and to stop engine.
On models with electric-start, use switch to
open ignition circuit, and to start and stop en-
gine.
2 Throttle Control Lever
Use lever to select engine speed. Move lever
to idle position (far right) for idle speed. Move
lever to Run position (far left) for weld/power
speed.
. Always place lever in Run position (far
left) for auxiliary power and for maximum
weld output.
3 Choke Control Lever
Use lever to change engine air/fuel mix. Move
lever to left if starting a cold engine. Move le-
ver to right if starting a warm engine.
4 Starter Handle (Recoil-Start Models
Only)
To Start (Recoil): open fuel valve, turn engine
switch to On, move throttle lever to Idle, set
choke, and pull starter handle. Open choke as
engine warms.
To Start (Electric): open fuel valve, move
throttle lever to Idle, set choke, and turn en-
gine switch to Start position. Open choke as
engine warms.
Y If the engine does not start, let engine
come to a complete stop before at-
tempting restart.
To Stop: turn engine switch to Off.
. Always close fuel valve after stopping
unit. Moving unit with fuel valve open may
cause carburetor flooding and make
starting difficult.
5 Welding Range Label
Use label to determine correct weld amper-
age based on electrode size, type, and mate-
rial thickness.
6 Current Control
Use control to select weld amperage. Control
may be adjusted while welding.
To Set Current Control: Use label to deter-
mine correct size electrode for material thick-
ness. Select electrode type and set current
control to corresponding amperage range on
nameplate. Adjust control within selected
range to obtain desired weld performance.
EXAMPLE:
Material Thickness: 1/8 to 1/4 in
Electrode Diameter: 1/8
Electrode Type: E-6013
Current Control Setting: 90 120 A
