Operation
with a pointed tool or a welders’ chipping hammer.
Stop welding
All that is required is to withdraw the electrode from the workpiece
thus breaking the circuit. Be careful with the end of the electrode,
as it will be hot! Provided the current setting is correct, the surface
of the workpiece will also melt by the intensity of the electric arc. A
degree of “penetration” is thereby obtained, and a complete “fusion”
of the workpiece and the deposited electrode is met.
Tip
Keep the welding current as low as possible for the job at hand to
maintain the best duty cycle from your welding machine, prevent
Thermostatic protection
This welder is automatically protected from overheating by a
thermal overload cut-out protector.
If the transformer overheats, the overload cut-out protector will
cut out has operated.
After cooling, the protector will reconnect the supply circuit and the
welder will be ready for further use.
NOTE: If the duty cycle of the machine is exceeded, the thermostatic
protection will activate.
