Terms of use

Arcuracy is reference information for comparing welding and cutting equipment. It isn't welding procedure, electrical or safety-compliance advice.

Ratings come from makers and retailers and can change; the machine's manual and rating plate are the final word. Tool results are starting points calculated from the figures shown and the values you enter.

Welding and cutting involve arc radiation, fire, fumes and electric shock. Follow the manual, wear eye protection of at least OSHA's minimum shade, keep combustibles away, ventilate, and have a licensed electrician install 240-volt circuits.

Product names, model numbers and images belong to their owners. Retailer links are offered for convenience; retailers set their own prices, stock and terms.
