Whimsical Welding. Hard hats festooned with sports logos have been available for years. Now welders can have some fun on the job too. Lincoln Electric's Viking series of self-darkening welding helmets offers eight patterns - movie characters, race cars, and the American flag - as well as basic black. No word yet on when the Green Bay Packer version will be released. Prices range from $175 to $240. Lincoln Electric Co., 216/481-8100, lincolnelectric.com.
