TIG Features |
|||||||||||
| Lift Arc Starts | Yes | No | Yes | Yes | No | Controlled contact arc ignition lets you start the arc in both AC & DC TIG without the use of High Frequency. | |||||
| High Frequency | Start Only | Start (DC) and Continuous (AC) | Start Only | Start Only | Start (DC) and Continuous (AC) | Because HF is only on to start the arc, it does not create HF interference issues in building/facilities. | |||||
| Pulser Control | Yes, Digital, Complete | Yes, Non Digital, Complete | Yes, Digital, Complete | Yes, Non Digital, Complete, Requires Special Pendent | Optional, Non Digital | The pulsing feature is standard on the Dynasty 350 and has expanded parameter ranges for more control. | |||||
| Max Pulse Frequency | AC=500PPS DC=5,000PPS |
AC=20PPS DC=20PPS |
AC=500PPS DC=500PPS |
AC=Not Spec. DC=2,000PPS |
AC=10PPS DC=10PPS |
Pulsing at high speeds between a high PEAK and a low Background amperage can constrict and focus the arc - which can reduce weld width and increase travel speeds. | |||||
| Sequencer | Yes, Digital, Complete | Down-Slope Only | Yes, Digital, Complete | Preset Upslope, Non Digital Down-Slope | Optional, Non Digital Complete | The standard weld sequence feature allows
the power source to control the entire weld cycle from start to finish. |

Yes, Digital | Yes, Digital | Yes, Non Digital | Digital control provides consistent preflow times. | |||||
| Postflow | Yes, Digital, Auto-Postflow or Adjustable | Yes, Non Digital | Yes, Digital | Yes, Digital | Yes, Non Digital | Auto Postflow calculates the length of
postflow time based on the amperage setting.
This eliminates the need to independently set the postflow time for different amperages. This feature preserves the tungsten and prevents porosity. |
|||||
| Spot Weld Timer | Yes, Digital (0-999Sec.) =16Min. 36Sec. |
No | Yes, Digital (0-5Sec.) |
Yes, Non-Digital (0-8Sec.) Requires Special Pendent |
Not Specified | The Dynasty 350 spot timer length of time is extended to 999 seconds. It also works with the sequence feature and can be used to automate timed welds. | |||||
| (AC) Independent Amplitude | EN=5-350Amps EP=5-350Amps |
No | No | No | No | Allows the EN & EP amperages to be set at
different values for the correct amount of cleaning and penetration. EP controls the cleaning action, while EN controls the penetration. |
|||||
| (AC) Balance | 30-99% EN | 35-85% EN | 35-90% EN | 50-85% EN | Not Specified | The Dynasty 350 provides extended balance control for fine-tuning the arc cleaning action and maximizing electrode life. | |||||
| (AC) Frequency | 20-400Hz | 60Hz | 15-150Hz | 40-100Hz, Requires Special Pendent |
60Hz | AC Frequency can focus the arc for increased directional control and arc stability. Lower frequencies produce a soft, wide puddle by spreading the arc. | |||||
