could cause serious injury to the operator and could damage the
equipment.
OPERATION
Performance Data Plate and Duty Cycle
On the machine, there is a plate that includes all the operating
specifications for your new unit. The serial number of the product is also
found on this plate. The duty cycle rating of a welder defines how long the
operator can weld and how long the welder must rest and be cooled. The
duty cycle is expressed as a percentage of 10 minutes and represents a
maximum welding time limit. The balance of a 10-minute cycle is required
for cooling. For example, a welder has a duty cycle rating of 30% at the
rated output of 90A. This means with that machine can weld at 90 A output
for three (3) minutes cut of 10 with the remaining seven (7) minutes
required for cooling. The duty cycle of your new welder can be found on the
data plate affixed to the machine.
Internal Thermal Protection
The thermal protection system will engage, shutting off all welder output if
you exceed the duty cycle of the welder. After cooling, the thermal protector
will automatically reset, and the welding functions will resume.This is
normal and automatic behavior from the machine. No user action is
required during this phase. However, you should wait at least ten minutes
after the thermal protector engages before resuming welding. You must do
this even if the thermal protector resets itself before the ten minutes is up,
or you may experience less than specified duty cycle performance.
CAUTION:DO NOT REGULARLY EXCEED THE DUTY CYCLE OR
DAMAGE TO THE WELDER CAN RESULT
Welding Preparation
An important factor in making a satisfactory weld is preparation. This
includes studying the process and equipment and practicing welding
before attempting to weld finished product. An organized, safe, ergonomic,
comfortable, and well-lit work area should be prepared for the operator.
The work area should especially be free of all flammables, and a fire
extinguisher and a bucket of sand should be available.
To properly prepare for welding with your new welder, it is necessary to:
● Read the safety precautions at the front of this manual.
