1.2.
Confirm the electrical grid connected to the welding machine is consistent
with the correct power supply of the machine.
1.3.
Confirm that the insulation layers on all the wires and cables of the welding
machine are intact and that the cable set is secure and correctly connected to
the machine.
1.4.
Confirm the machine is freely vented and that the vents on the machine are
not obstructed and no objects are lying on the machine body.
1.5.
Connect and tighten the earth cable to the negative pole. Clamp the other end
of the cable to the workpiece.
1.6.
Connect and tighten the electrode cable to the positive pole. Use the
electrode holder to clamp the electrode.
1.7.
Turn the machine on
-
the power indicator lights up and the fan becomes
operational.
1.8.
Set the parameters for the welding job. The welding current is set in
accordance with welding rod specifications. (See table below).
1.9.
Commence welding using short
-
circuit arc ignition.
1.10.
Complete the operation following the normal procedure. During the
operation the parameters can be adjusted to suit the situational demands.
1.11.
After completion of the operation, turn off the power using the switch on the
rear panel of the machine.
