To start the arc, scratch the electrode over the spot to be welded in a similar way to how a match is
lit. The 75V no-load voltage ignites the electrode quickly, and direct current (DC) allows the electrode
to melt evenly. If you are a beginner do not expect good results on the first attempt, take training
courses and courses in welding
10.4 Protections
Bonded electrode (ANTI STICK)
If the electrode does not ignite, or the arc goes out while the electrode is being welded, it may stick to the
part to be welded. This situation is detected by the electronic board of the equipment and the welding
current is automatically reduced. This allows you to free the stuck electrode from the surface to be welded
by moving it back and forth.
While the electrode is attached, the warning indicator
holder and the ground is indicated in the same way. If the electrode cannot be detached, remove the
electrode holder and remove it manually using the appropriate protection and tweezers. Be careful as the
electrode can be very hot.
Duty cycle excess protection or thermal control device.
When there is protection by reaching the maximum duty cycle, or by internal heating of the machine,
the arc is extinguished and the protection of the machine is activated
down to continue its normal operation. Do not turn off the welder, allow the fans of the equipment
to cool the machine's power components until the machine protection deactivates. Only until this
moment can the machine be switched off or start welding again.
Note: to preserve the power components of the welding machine from heat accumulation, do not
disconnect it immediately after activation of the protection, as described above.
WELDING PROCEDURE
11.
Holding the mask IN FRONT OF THE FACE, rub the tip of the electrode on the workpiece as if you
were lighting a match.
WARNING: do not hit the electrode on the workpiece this could damage the electrode and make
the welding process difficult.
As soon as the arc ignites, try to maintain a distance from the workpiece equal to the diameter of
the electrode in use. Keep this distance constant during welding. Remember that the angle of the
electrode as you go should be 20-30 degrees.
At the end of the weld bead, bring the end of the electrode back, to fill the weld crater, quickly lift
the electrode from the weld pool to extinguish the arc.
