Indicates a hazardous situation which, if not avoided,
could result in death or serious injury. The possible ha-
zards are shown in the adjoining symbols or explained in
the text.
Arc rays can burn eyes and skin −wear a welding helmet
with correct filter, and cover exposed skin with nonflam-
mable clothing.
NOTICE Indicates statements not related to personal injury.
Indicates special instructions.
Welding sparks can cause fire or explosion. Move flam-
mables away. Do not weld on closed tanks or barrels −
they can explode. Clean tanks or barrels properly.
Beware of electric shock from welding electrode or wiring.
Touching the electrode while in contact with the work or
ground can cause electric shock. Always wear dry
gloves. Keep all panels and covers closed.
Breathing welding fumes and gases can harm your
health. Welding requires good ventilation. If ventilation is
impossible, such as when welding in a confined space,
use an air-supplied respirator.
CALIFORNIA PROPOSITION 65 WARNINGS

3. Adjusting Amperage Or Voltage
.On some welding power
sources, the front panel output
control setting does not matter
and the Remote Hand Control
adjusts the full range of the
welding power source output.

In Example: Min = 40 A In Range B,
Output = 120 A (50% of 40 to 200)
Max = 200 A In Range B

Place switch in On position for open-circuit
voltage. When switch is in Off position no
output is present.
In Example: Min = 5 A
Output = 200 A (100% of 5 to 200)
Max = 200 A
