SECTION 4: OPERATIONS A duty cycle is the number of minutes out of 10 Operation Safety minutes that the welder can safely operate at the current amperage output without over-heating. For instance, the Model H8154 has a stick duty cycle of 35% at 130A output. This means that the welder can operate continuously for 3.5 minutes at 130A output, then the arc must be stopped for Damage to your eyes and lungs could result at least 6.5 minutes to allow the welder to cool from using this machine
