makeithot I believe Chris is working on DOD "boats" which are a bit heavier built then the average fishing vessel I rekon. Also because they are GOV contractor there of course is more regs and money to be made.
Chris I figured you would get a variety of perspectives if you asked. That's one thing the forum can provide about every time. And you are 100% welding screens? In a production boat??? Bwahhaahhhaaaahah Get in there and NAIL it down that's Al boat work.
My two cents: I have been welding on shiny metal for the better part of my 22+ years, whether smaw, gmaw, a little fcaw, saw, gtaw and even lasers. I know that the right shade as well as the right setup (i.e. taped on leather, hoods, blinds etc.) can be lifesavers to say the least. How thick and how many amps are you welding at Chris? I have "blue" eyes and at 170 amps or so I have to move to a 13...at 200+ I really need a 14 on AL whether its Mig or Tig. Aluminum really sux when there is grinding going on because it stays airborne...it gets in the eyes easily. You have eliminated that problem, I think so from what you have told me anyway...you are right in trying darker shades ASAP....When I am welding even on the tiny delicate stuff..I adjust my shade to where I only see the puddle and slightly the joint. If your burning that wire and lighting up the world, seeing inches around your puddle...well that's bright brother....and hard on your money making orbs in the long run.
One other problem you might want to consider is AL's post:
"Welding aluminum produces very intense UV. The UV ionizes oxygen producing ozone. The ozone is actually toxic to the body if the concentration is high or long. The fumes produced by welding aluminum, well, we all know that isn't doing us any good at all.
Eye drops for the dry eyes, a darker filter lens, and complete covering of the all skin and the back of the head is imperative to working safely. A pressurized respirator that blows filtered air across the face and provides a full face mask is a worthwhile investment."
Good straightforward post AL
I never even realized the ozone part, "that's that burn your nose just a bit smell isn't it??" . As far as the second part, despite the health risks, Mig welding smoke on AL is about as ACRID as Mig welding smoke from stainless....both are bad for your respiratory system in time,,,,but both are irritating too your eyes as well, or at least it is to my eyes. The idea of fresh air blowing across my ocular sensors if I was laying pounds of wire, AL or stainless, sounds like a great idea to me. Hmmmm I wonder if thats why Optrel offered those hoods with the built in fans, not quite the same as fresh air, but still. Anyway I am just trying to reinforce what was already said, the fumes are something serious to contend with despite the fact of breathing them in.....simple exposure to them can cause problems. And for some PEOPLE those problems can be way more problamatic then for others....a slight irritation for some....crippling and debilitating for others.
Start with a "dark" shade for a couple of days.....if your problem persists then I would say its the smoke/fumes if you have eliminated all airborne "from grinding this is the edit" particle issues.
