Commando, I shine a bright clamp-on light on my weld area. Standard indoor overhead lighting does not light the weld area nearly enough for me. This helps me immensely. I use .035 wire for my muffler welding & sometimes use a circular motion & pull down. The right amperage & shielding gas make all the difference in the world. I used to plug-into a 15 amp outlet & got crappy welds. Then I ran a new 20 amp circuit & it was like a whole different welder. No more problems anymore. Also, I use an auto dimming helmet.
