As the welder produces the desired power output for the welding operation, some of the power is converted to heat. In order to protect the welder components from
A duty cycle is the number of minutes out of 10 minutes that the welder can safely operate at the current amperage output without
The Model H8151 operates with an efficient cool- ing fan (at the rear of the welder) and has an internal thermostat that will shut the welder down at the end of the duty cycle. This will be evident by the loss of welding circuit and the red warning light on the face of the welder. When the welder has cooled sufficiently, the internal thermostat will allow the welding circuit to once again be used and the red warning light will go out.
Note: Most electrodes used with arc welding are consumed within a few minutes, so the welder has a chance to cool down when the welding cir- cuit is stopped to install a new electrode.
