• ELECTRIC SHOCK CAN KILL.
Unless using COLD FEED fea-
ture, when feeding with gun trig-
ger, the electrode and drive
mechanism are always electri-
cally energized and could
remain energized several sec-
onds after the welding ceases.
• Do not touch electrically live part or electrode
with skin or wet clothing.
• Insulate yourself from work and ground.
• Always wear dry insulating gloves.
• Do not operate with covers, panels or guards
removed or open.

POWER-UP SEQUENCE
When the POWER WAVE
®
300C is powered it can
take as long as 30 seconds for the machine to be
ready to weld. During this time period the user inter-
face will not be active.
DUTY CYCLE
The POWER WAVE
®
300C has 100%, 60% and 40%
duty cycles. The duty cycle is based on a ten-minute
period. A 60% duty cycle represents 6 minutes of
welding and 4 minutes of idling in a ten-minute period.
See machine specifications section for amperes and
machine ratings.
