Damage to your eyes and lungs could result from using this machine without proper protective gear. Always wear safety glasses, welder's helmet, and a respirator when oper- ating this welder.

NOTICE

If you have never used this type of machine or equipment before, WE STRONGLY REC- OMMEND that you read books, trade maga- zines, or get formal training before begin- ning any projects. Regardless of the con- tent in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training.

As the welder produces the desired power output for the welding operation, power is converted to heat. In order to protect the welder components from over-heating, each welder has an estab- lished duty cycle, which varies depending on the amperage output being used.

A duty cycle is the number of minutes out of 10 minutes that the welder can safely operate at the current amperage output without over-heating. For instance, the Model H8155 has a duty cycle of 45% at 50A output. This means that the welder can operate continuously for 4.5 minutes at 50A output, then the arc must be stopped to allow the welder, using the cooling fan, to cool off for at least 5.5 minutes before starting the arc again.

The Model H8155 has a cooling fan and an inter- nal thermostat that will shut the welder down if the duty cycle is exceeded. This will be evident by the loss of welding circuit and the orange warn- ing light on the face of the welder will illuminate. When the welder has cooled sufficiently, the inter- nal thermostat will re-establish the welding circuit and the orange warning light will go out.

Always treat the welding components as if they carry live welding current, even when the welder reaches the duty cycle limit and shuts down. When the welder re-establishes the welding current, the electrode and work lead will immediately carry live welding cur- rent. Ignoring this warning could result in serious personal injury or death.
