    1-GENERAL REMARKS 1-1 Power source features This series TIG welding machine can perform DC TIG, Pulse TIG, AC TIG,AC pulse TIG and SMAW processes. This series welding machines enjoy reasonable static characteristic and sound dynamic characteristic.. Features and benefits: -MCU controlled technology -Self-diagnostic function with error code display -AC square wave and sine wave waveform output -30 sets of parameters can be stored...

  • Page 8: Duty Cycle

    1-4 Duty cycle Duty cycle is percentage of 10 minutes that a machine can weld at rated load without overheating. If overheats, thermostat(s) will open, output stops. Wait for fifteen minutes for the machine to cool down. Reduce amperage or duty cycle before welding. Note! Exceeding duty cycle can damage the machine and greatly reduce its lifespan.
