SECTION 4: OPERATIONS
Operation Safety
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.
Welder Duty Cycle
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 H8154 operates with an efficient cool- ing fan (at the rear of the welder) and has an internal thermostat that will shut the welder down if the maximum duty cycle has been reached. Shutdown will be evident by the loss of welding circuit and the illumination of the yellow warning light on the face of the welder. When the welder has cooled sufficiently, the internal thermostat will
Note: Most electrodes used with stick 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.
However, with TIG welding, the operator needs to plan his work within the duty cycle constraints of the welder.
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
