From Miller to You Thank you and congratulations on choosing Miller. Now you can get the job done and get it done right. We know you don’t have time to do it any other way. That’s why when Niels Miller first started building arc welders in 1929, he made sure his products offered long-lasting value and superior quality. Like you, his customers couldn’t afford anything less. Miller products had to be more than the best they could be. They had to be the best you could buy. Today, the people that bu

ARC RAYS can burn eyes and skin. BUILDUP OF GAS can injure or kill. Shut off shielding gas supply when not in use. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays Always ventilate confined spaces or use that can burn eyes and skin. Sparks fly off from the approved air-supplied respirator. weld. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 li
