DEFINITION OF WELDING TERMS

NON-SYNERGIC WELDING MODES

• A Non-synergic welding mode requires all welding process vari-
ables to be set by the operator.
SYNERGIC WELDING MODES
• A Synergic welding mode offers the simplicity of single knob
control. The machine will select the correct voltage and amper-
age based on the wire feed speed (WFS) set by the operator.
WFS
• Wire Feed Speed
CC
• Constant Current
CV
• Constant Voltage
GMAW
• Gas Metal Arc Welding
GMAW-P
• Gas Metal Arc Welding-(Pulse Arc)
GMAW-STT
• Gas Metal Arc Welding-(Surface Tension Transfer)
SMAW
• Shielded Metal Arc Welding
FCAW
• Flux Core Arc Welding
CAG
• Carbon Arc Gouging

DUTY CYCLE

The POWER FEED™ 25M is rated for 500 amps, 60% duty cycle.
The duty cycle is based on a 10 minute cycle.
For example, when welding at 500 amps, the POWER FEED™
25M may run continuously for 6 minutes and then must sit idle for
4 minutes.
