8-3. Emergency Stop
The equipment includes an emergency stop device.
Press the emergency stop switch if you want to immediately stop the engine when an
emergency occurs in the work area, the equipment suffers an operating fault, and
similar circumstances.
<Note>

After stopping the engine using the emergency stop device, turn the starter switch to
"STOP".

Do not strike the emergency stop switch with a hammer or similar tool.

Only use the emergency stop switch for emergency stop purposes.

If the engine does not stop when the emergency stop switch is pressed, turn the fuel
lever to "CLOSE". The engine will stop a few minutes afterwards.
9. Using as a Welder
9-1. Welding Cable Selection
Use welding cables with a cross-sectional area that is larger than the proper cross-
sectional areas indicated in the table below.
Using cable that is less than the proper cross-sectional area reduces the weld output.
<Note>

Use welding cables when they are completely extended (not coiled). Using a cable that
is coiled reduces the weld output.
Proper Cable Cross-Sectional Area (Units: mm 2 )
Weld Current
20m 30m 40m 60m 80m 100m
300A 30 38 50 80 100 125
250A 22 30 38 60 80 100
200A 22 30 30 50 60 80
150A 22 22 22 38 50 60
100A 22 22 22 30 30 38
9-2. Welding Polarity
There are "+" (positive) and "
-
" (negative)
welding output terminals.
Refer to the table below to select a polarity
corresponding to the work you are performing.
<Note>

Use the polarity indicated for the welding rods
being used if so indicated.

When welding with 2 persons using different polarities for the same base material, a
single worker must not hold 2 holders because the voltage between the 2 holders could
become high and there may be a danger.
