Helmet Shade# for Low Amp TIG?
I've been mostly tigging al; no problem w/ #10 shade HF A/D Helmet. Just
started light gauge (22) steel sheet at 30A. The arc light is so dim at low amp I can't see the work and puddle properly. What do you guys use here? Do you use an aux halogen light source to illuminate the work? Need to check out the range of shade levels on some other helmets. Maybe one that goes down to #8?

JR Dweller in the cellar I recently had some light-gauge steel to TIG, and once I got a helmet that would respond to the dim arc, had good results with simply increasing the illumination on the work. That worked better than changing to a lighter shade. -- Ted Bennett |

JR Dweller in the cellar I mounted a 300 watt outdoor halogen light 4 feet above my welding table, directly over the side I do tig from. Works for me Gunner "The importance of morality is that people behave themselves even if nobody's watching. There are not enough cops and laws to replace personal morality as a means to produce a civilized society. Indeed, the police and criminal justice system are the last desperate line of defense for a civilized society. Unfortunately, too many of us see police, laws and the criminal justice system as society's first line of defense." --Walter Williams |

JR Dweller in the cellar Greetings JR, Even though a lighter shade lens will still block all the UV as well as a darker shade lens will I have found that using bright lights instead makes the work easier to see. Especially the areas adjacent to the weld because the tiny arc isn't bright enough to illuminate these well. Cheers, Eric |

Helmet Shade# for Low Amp TIG?
Thanks for the suggestions.
Problem solved. Got a new helmet: http://www.harborfreight.com/cpi/cta...emnumber=46092 And a quickie light source: http://www.harborfreight.com/cpi/cta...emnumber=40809 On sale for $3.99. It has a tripod mount base, so I mounted it on an old tripod and soldered two clips to the cord end. Runs off a battery charger. The helmet works extremely well. The OFF shade is much clearer than my old HF #10 helmet. The infinitely adjustable 9-13 shade works perfectly, and it comes with an extra lens shield. Now I can see WTF is going on...

Sounds like at least part of your problem was a dirty lens. "The OFF
shade is much clearer than my old HF #10 helmet." I keep several extra lens's and cover plates, put in fresh ones when I plan to do some low amperage work. I can't use the HF autodark helmets. Stupid bifocals aren't at the right angle. And after the hassle of getting used to them, I'm NOT going to do try all the glasses tricks I've seen. Sheesh, even my eye doctor mentioned the bifocals with an extra lens at the top of the glass. JR North wrote: Thanks for the suggestions. Problem solved.
