‰
Do not place or operate this machine on a surface with an incline greater
than 10°from horizontal.
‰
This machine must be located where there is free circulation of clean air
without restrictions for air movement to and from the air vents. Do not cover
the machine with paper, cloth or rags when switched on.
‰
Dirt and dust that can be drawn into the machine should be kept to a

Duty cycle
The duty cycle of a welding machine is the percentage of time in a 10 minute cycle
at which the welder can operate the machine at rated welding current.
Example: 60% duty cycle:
Welding for 6 minutes. Break for 4 minutes.
Excessive extension of the duty cycle will cause the thermal protection circuit to
activate. See “Technical Specifications”.
