Use control to change engine air/fuel mix.
Move control to right (Choke) if starting a cold
engine. Move control to left (Run) if starting a
warm engine.

Starter Handle
To Start :
D Open fuel valve (see Section 5-3).
D Turn Engine switch to On.

This unit has a low oil level shutdown to
prevent starting an engine that is too low
on oil. The low oil level shutdown may not
stop a running engine. Check oil level if
the engine does not start, or has stopped
and cannot be restarted.
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.
4 Amperage Control
Use control to select weld amperage. Control
may be adjusted while welding. Set Amper-
age control at max. for full generator power
output at ac receptacles.
To Set Amperage control: Use electrode
chart (see Section 6-3) to determine correct
size electrode. Select electrode type and set
Amperage control to corresponding amper-
age range on nameplate. Adjust control within
selected range to obtain desired weld
performance.
EXAMPLE:
Electrode Type: 6013
Electrode Diameter: 1/8
Amperage control Setting: 80 − 125 A
6-3. Amperage Selection Table For Stick (SMAW) Electrodes
226 005-A
Use table to select correct amper-
age for the electrode being used.
.
For best results, use Stick
electrodes designated for AC
welding.
Values listed are suggested settings. Actual settings may vary depending on personal preference and/or specific application.
Suggested electrode for beginners is E7018 AC.
