Respirator recommendation - supplied fresh air? Any recommend for full or half face respirator, I would prefer supplied fresh air, something that does not break the bank. I do a fair amount of plasma cutting mild steel and stainless steel, grinding with angle and bench grinder, spatter and over weld removal with air operated tools such as high speed cut-off wheels, carbide burr removal tools. And of course welding, mostly with MIG and TIG. I use a ventilated welding boot but by the end of the day I have black buggers (sorry, did not mean to be gross). I've been using a standard half mask with twin cartridges during plasma and grinding but nothing for welding. Any opinion on full face supplied air respirators?
thanks
