THERMAL OVERLOAD
The ‘Thermal Overload’ shuts off the welder when it becomes too hot, due to the duty
cycle being exceeded. This is to prevent damage to the machine.
When this occurs, the warning lamp shown will glow (amber). Allow the welder to cool,
until the amber light extinguishes before resuming work.
DUTY CYCLE
These welders are covered by Australia Standards
AS 60974-1 and EN 50199
Approval No:
ESV110294
, where the duty cycle is expressed as a percentage of time the
machine may be used in a given period for a specified welding current. For example
10% @ 180amps this means the machine can be welded for 1 min in any given 10 min
period at 180amps - 40°C ambient
