Steve,

High frequency is the most common method of starting the AC TIG arc. Continuous high frequency is used on some TIG machines to help stabilize the arc. Miller's newer TIG inverters like the Dynasty series use high frequency to start the arc but it is not continuous.

High frequency is not used in the MIG process. MIG welding of aluminum is a DC process. I usuaully have the contact tip flush with the gun nozzle and run with a 3/4" wire stickout.

Properly set up and grounded high frequency should not shock you. A number of years ago there was a welder running TIG on an with an engine drive and a high fequency box and did not ground the HF box or welder. He ran this way for years. One day something went wrong and he becae the ground for the HF and it killed him. It was also a rainy day. There were other factors involved. I have never had a problem wwith HF starts or continuous HF on any machine.

Caught a re-run of Clark Howard radio show today. He is apparently having problems with chatter on some of his message boards also. He requested that those involved clean up their act. He pointed out that his boards exist for education and information sharing not for recreation.
