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.

SECTION 4 − INSTALLATION 4-1. Important Information Regarding CE Products (Sold Within The EU) A. Information On Electromagnetic Fields (EMF) This equipment shall not be used by the general public as the EMF limits for the general public might be exceeded during welding. This equipment is built in accordance with EN 60974−1 and is intended to be used only in an occupational environment (where the general public access is prohibited or regulated in such a way as to be similar to occupational use) by an expert or an instructed person.
4-4. Duty Cycle And Overheating Duty Cycle is percentage of 10 min- utes that unit can weld at rated load without overheating. If unit overheats, thermostat(s) opens, output stops, and cooling fan runs. Wait fifteen minutes for unit to cool. Reduce amperage or duty cycle before welding.
