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 any
damage to the machine.
When this occurs, the warning lamp
shown will light up. Allow the welder
to cool until the amber light
extinguishes before resuming work.
DUTY CYCLE
These welders are covered by
regulations EN 60974-1 and EN 50199,
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.
Using the example shown, which is an
illustration of the data plate;-
e.g. when welding at 40 amps the
machine may be used for 6 minutes
(60%) in any 10 minute period.
WELDING TECHNIQUE
•
Try to maintain the tip of the nozzle at an angle of approx. 45O and at a
constant distance of approx 5-7mm from the workpiece.
•
Try to maintain a constant speed of movement with the torch.
•
Do not weld in windy conditions or in an area where ventilation is a
problem, or where air flow fluctuates.
•
ALWAYS keep the wire and nozzle clean...NEVER use rusted wire.
•
Avoid sharp bends or kinks in the welding hose.
•
Whenever possible, clean out the wire liner with compressed air when
replacing the wire spool.
•
Periodically remove the dust using LOW PRESSURE compressed air within
the casing. Adequate heat dissipation is essential during the welders
operation.
