Front and Rear Panel components:
1- Power Indicator Led : Shows the On/Off state of the machine.
2- Negative (–) Welding Cable Connection : Welding current negative (–) output connection.
3- Overload/temperature Warning Led : These leds light up when the machine cannot provide
output current sue to overheating. This situation is encountered when the ambient temperature
rises above 40°C and the duty cycle (operating efficiency) of the machine is exceeded. Leave the
machine on and wait until it cools off. The machine will be ready for operation again when the
lamp goes off.
4- Welding Current Control Knob : Potentiometer used to set the output current used during
welding.
5- Positive (+) Welding Cable Connection : Welding current positive (+) output connection.
6- On/Off switch : Controls the main power input to the machine.
7- Input cable : This machine is provided with a plugged input cord. Connect it to the mains.
Coated Electrode Welding :
The following actions need to be done before starting the welding procedures:
1- First determine the pole appropriate for the electrode used. This information can be found in the
data sheet of the electrode. Then connect the welding cables to the output according to the pole
required. For example; if DC (+) is to be used, connect the electrode cable to the (+) output of
the machine (5) and the grounding cable to the (–) output (2). Selecting a wrong connection may
result in unstable arc formation, too much splashing and the electrode sticking to the work piece.
Turn the connecter 1/4 clockwise after inserting in the plug with the guide pin on top. Make sure
that the connector is seated firmly in place without tightening too much. Otherwise, the loose
sockets may overheat and burn out during a prolonged period of use or high welding currents.
2- Attach the electrode to the electrode clamp.
3- Connect the work clamp to a clean place on the work piece free of paint or rust with the jaws in
complete contact.
4- Insert the input cable to a suitable mains supply.
5- Perform the following checks before starting the welding procedure:
a- Make sure that the welding machine is grounded securely.
b- Make sure that all contact surfaces, especially the contact between the work clamp and work
piece are well secured.
c- Check that the welding cables are attached correctly.
d- The particles and sparks splashing around while welding may cause a fire. Therefore, make
sure that no flammable materials are present in the welding area.
6- Turn on the On/Off switch (6).
7- Adjust the proper welding current to be found from the electrode data sheet according to the
electrode diameter, type and welding position with the "Welding Current Control Knob (4)".
In general, the welding current should be between the values indicated below. However, adjusting
your settings according to the values setout in the catalog of the welding electrode manufacturer
recommendations would be more appropriate.
This welding machine is designed for 2.50 and 4.0 mm diameter welding electrodes with
rutile and basic coating used for light welding operations.
ø 2.50 mm : 70 - 100 A
8- Start welding observing the welding rules.
Preparation for Work - 2
