Installation set up for ARC (Stick) Welding with RAZOR 250K
(1) Turn the power source on and select the ARC function with the TIG/ARC/MIG selector switch.
(2) Connection of Output Cables
Two sockets are available on this welding machine. For ARC welding the electrode holder is shown
be connected to the positive socket, while the earth lead (work piece) is connected to the negative
socket, this is known as DC+ polarity. However various electrodes require a dierent polarity for
optimum results and careful attention should be paid to the polarity, refer to the electrode
manufacturers information for the correct polarity.
DC+ Electrode connected to output socket.
DC- Electrode connected to output socket.
(3) Set the welding current relevant to the electrode type and size being used as recommended by the
electrode manufacturer.
(3) Set the welding current using the amperage
control dial.
(6) Hold the electrode slightly above the work
maintaining the arc while travelling at an even
speed.
(4) Place the electrode into the electrode holder
and clamp tight.
(7) To finish the weld, break the arc by quickly
snapping the electrode away from the work piece.
(5) Strike the electrode against the workpiece to
create an arc and hold the electrode steady to
maintain the arc.
(8) Wait for the weld to cool and carefully chip
away the slag to reveal the weld metal below.
WARNING:
Disconnect the Electrode Holder cable from the machine before using MIG function. If cable is not disconnected welding voltage is pres-
ent and can cause arcing or ash.
WARNING:
Ensure that an approved welding helmet, protective clothing and gloves are use for all welding operations
