Question about Miller SYNCROWAVE 250 DX TIG RUNNER WELDER 951117
When starting to weld alum. arc will start for a few sec. then stops and HLP comes up on display
It sounds like you need to change out your SCR chip on your motherboard; Miller makes one that i have installed on all our 350xl's, I don't have the number on hand but i can get it for you tomorrow.

Testimonial: "appreciate the help."
I think you mean you have a Miller Synchrowave 200.
Typically, you would want to use AC below about 250 amps. In this case (to keep it simple), use AC, adjust your balance to about 4, use an 1/8" pure tungsten, pure argon at about 20CFh, and set the panel at 170amps to get things started. For general purpose, use 4043 filler.
Now - these are just generic settings, but they will get you going.

The tungsten point has to be quite sharp, the gas has to give constant flow relative to the tip size and shroud and the amps adequate to create a spark without immediately making a mess of the parent metal. The two most common issues will be the cleanliness of the parent metal and the Gas flow. Assuming you have all this set up, it actually sounds like you have a problem with your mask as you shouldn't get flashed at all.
I had a similar problem once with a solar powered auto mask because the batteries had died and wouldn't recharge. I retro fitted a couple of button cell 2032 to the mask and it's working fine.
