fogging helmet

[Arc weld]

I'll have to ask if they have a special breakfast menu for welders the next time I'm at Wendy's. They use square hamburger patties cause they don't cut corners but their pancake hoods are round. What's up with that.:confused3:

Rubbing dish soap on the lens until it disappears also helps to reduce fogging. A lot of pipeline welding in winter is done inside a tent or a special shack that is lowered over the pipe. They don't just start welding on the cold pipe. They have to preheat it and the shacks have heaters as well. You have to be a bit of a contortionist to weld pipe and it would be very hard to do with bundles of clothes on to keep warm.

Pancakes are for right handed or for left handed. They are flat front and bent to cover one ear. Glass is in a face plate ( like goggles) only goes around eyes, must be fitted to face. Does not flip at all. Lift off eyes or put on eyes. Sarge is another one.

do these hoods have a flip up lens?

This outfit use to sell the flip lens pancake hoods. You have to register to look around on their site. I took a quick look but didn't see them. I don't recommend them, they are very heavy on the bridge of your nose after a few hours of welding.:thumbdown:

Spit works, wipe most of it off.
Fresh cut potato, but you may not have that readily available.
Whatever scuba divers use, I forgot to look that up after posting about it the last time and I haven't dived since.

Scuba divers still use spit and work it in. Nothing on the market is better although there is a product that tastes like lemon juice that works but still not better than spit. I don't know how spit works to prevent fogging, but it does. I have never used it in my hood though. I don't have a fogging issue now, I have a sweating issue. If welding when your hood is cold, the best way to prevent fogging is to warm the hood up first using hot air from any source (hair dryer, cutting torch(what I used) etc. If using a torch, just hit the high pressure air while holding the torch a foot or more away from the hood, you don't want to melt the hood or the CR39 plastic lens, just a few seconds is all it takes to get the hood up above body temps and it wont fog.

Never seen these pancake welding hoods before, and I been around welding a lot, do these hoods have a flip up lens?

The old ones were built on the style of a pair of cutting googles and had to be raised up and down the same way. Most places now wont let welders use them as you have to have a hard hat on when welding and no way to use them with a hard hat. I am glad I stopped welding about the time they(Brown & Root) required use of hard hats. They sure made it hard on the neck due to extra weight and when getting under the bottom of a pipe when you had to lean sideways and the hood wanted to slide to a vertical position unless it was tightened so tight on your head that your head felt like it was in a vise. I think they finally got some hard hats made to weld in that helped a bit and were a bit lighter but the first ones were just a clamp on band like a face shield and a regular hard hat which wouldn't stay on your head at all.

Fairly sure that "fogging" is in fact condensed small water particles that stay separated.
Spit, potato juice and whatever_else "work" by reducing surface tension, thereby allowing the particles to coalesce. (simplified)

Yeah was gonna chime in brilliantly with 'spit' but the smart folks here already chimed in... costs nothing and it is always at hand! The scientific solution to reducing fogging is to reduce the surface energy/tension on the substrate. Natural saliva does a wonderful job in that regard, reducing the tendency for tiny water droplets to attach. Ironically, my profession involves just the opposite... we strive to achieve high surface energy to adhesively bond materials maximizing adherence.

Welding advice with a little humor, I love it, I keep re-reading about what your "profession" is, and it could only mean one thing, your a Politician that say's to spit on my lens so I can see the light, more clearly. But spit on the lens, gross, I tried that once, and I couldn't my wife to rub it in, and now I have a cold, don't want to catch my cold again in the same week, dish soap or Rain X sounds good-ish.... and if I'm elected, then I will "strive to achieve high surface energy"

I wear a respirator the entire time I'm in the garage because I switch back and forth between cutting, grinding, and welding. It exhausts out the bottom, so nothing fogs.... keeps the black boogers away too! : )
