When the machine is turned ON, an auto-test is executed and power
LED (GREEN) lights up and display will ON. The Machine is ready to
operate when the Front Control Panel lights up the Power LED ON.
The below listed parts are labelled in the product overview.
Apart from two or three, all other parts are common to each
machine.
Current adjusting knob
:
Potentiometer is used to set the output current during welding.
Arc Force Regulator
(For M220-76 & M250-104):
Arc force is a temporary increase of the output current during
welding when the arc is too short. It also enhances simple position
welding, making the job easier. In order to produce an outstanding
weld performance on a variety of electrodes, the Arc Force can be
finely adjusted with a simple knob.
Hot start Regulator
(For M250-104)
:
Hot Start provides excellent arc ignition without the electrode
sticking and avoiding any metallurgical default in the weld.
Anti-sticking
(INBUILT)
:
This electronic device minimizes the short circuit current in the
event of the electrode sticking to the work piece. If a short circuit
does occur, it will be easy to remove the electrode from the work
piece and the electrode gun and cable will remain undamaged. It
also serves as a safety device in protecting the operator.
Multi metal capability
(For M220-78):
This feature allows the machine to weld Zinc, Carbon steel, Copper,
Iron and Aluminium.
This feature is achieved only by M220-78.
