This is a common question.  Essentially, Duty Cycle is a measure of how long a welder will operate for before it overheats and cuts out. If you’re more of a Watcher than a Reader, you may prefer a Video Explanation There are 3 key bits of data to Duty Cycle figures: Amps, a Percentage Figure […]

An Oxy Acetylene Flame will fall loosely into one of three types: Neutral, Oxidising and Carburising Neutral Oxy Acetylene Flame A Neutral flame is achieved when there are equal amounts of Oxygen and Acetylene. A Neutral Flame is so named because it has no chemical effect on the molten metal. Key characteristics of a Neutral […]
