TROUBLESHOOTING & REPAIR
AC TIG MODE (BALANCED WAVEFORM)
CAUTION
HIGH VOLTAGE / HIGH FREQUENCY can damage test equipment.
•Perform all voltage and waveform checks with high frequency circuit OFF.

20 volts | 2 ms |
MACHINE LOADED TO 350 AMPS
AT 34VAC
This is a typical AC output voltage waveform generated from a properly operating machine. Note that each vertical division represents 20 volts and that each horizontal division rep- resents 2 milliseconds in time. The machine was loaded with a resis- tance grid bank. The TIG 355 display read 350 amps at 34 VAC.
Note: Scope probes connected at
machine output terminals: (+) probe to electrode terminal,
