Load Duration Factor
Load duration factor refers to the ratio that practical work time accounts for
the whole work time (10 minutes is 1 cycle). For example, 60% load duration
factor means that weld is made for 6 minutes and then zero load is for 4
minutes. Rating load duration rate compares with rating current. When the
equipment is used below rating current, if even the equipment may be used in
case of high load duration factor. At this time the calculation equation of load
duration rate as following:

Placement of Welding Machine
In placement, please pay attention to the following items:
(a) Lay in the place as possible where the ground is flat and vibration is little
and which is more than 20cm far from wall.
(b) Please put it in the clean and dry place where iron powder, dust, paint are
little.
(c) Please put the machine in the place where rain pouring can be avoided
and which is not subject to the erosion of sea water
