Striking The Arc
Lower the electrode slowly and proceed to strike the electrode
tip against the desired join area on the work piece as if you are
striking a match. As soon as you have the arc, try to maintain
a distance from the work piece equal to the diameter of the
electrode being used, eg. 2mm electrode, 2mm gap.
Slag
Slag is refuse left around the weld after welding. This should only
be removed after the weld has cooled down and is no longer
glowing. A face shield must be worn during removal of slag.
Use the chipping hammer/wire
brush to break off and clean the
weld of slag.
Thermal Overload Protection
All Welders have a feature called a duty cycle. Duty cycle on a
welder refers to the time in which the welder operates during
normal welding. A welder can only weld for a certain continuous
period of time before it requires to cool down.
If the internal components of the welder should become hot
the welder could overheat. If the welder overheats the Thermal
Overload Protection feature will automatically shut down the
welder.
THIS CAN OCCUR IN HEAVY USE AND DOES NOT INDICATE A
FAULT.
The Welder will cease to weld
and the Thermal Overload
LED light will turn on. This
LED indication light is just to
inform you that your welder is
becoming too hot and requires
to cool down to protect the
internal components of the
welder.
Do Not turn your welder Off as the welder has an internal cooling
fan and this will assist your welder to cool down quicker. Reducing
the cooling time will enable you to get back to your welding job
quicker.
Depending on how many Amps or how heavy the welding you are
doing the cooling time may take up to 10 minutes for your welder
cool down so you can return to your welding job.
Duty cycle % as referenced on the rating label are based on 10
minute intervals. For instance with a 20% duty cycle, one can weld
continuously for 2 minutes, but then must wait 8 minutes for the
welder to cool.
Lower current levels have longer duty cycles.
