i am stuck cause my Miller Dynasty 280 TIG arc won’t start at 120 amps, And there is no spark. Any help?

No arc is likely a bad torch. Check torch cable for breaks, And use 3/32-inch tungsten. my arc started fine after that. Clean with alcohol, And check connections.

Use a new torch cable, It is more reliable.

Bad ground is causing no spark. Check the clamp, My Dynasty works now.

Check high-frequency setting, my arc started after I adjusted it. Use 25 CFH.
