SCREENS AND SHIELDS.
Using screens and shields selectively from other cables and equipment in the work area can
alleviate interference problems. In special applications, the total protection of the installation
can be considered.
OPERATING INSTRUCTION.
WELDING.
After having made all the necessary electrical connections, both for the power cable and the
welding cables, proceed as follows:
Fix the uncoated end of the electrode in the electrode holder (12) and connect the earth clamp
(13) to the piece to be welded, always ensuring good electrical contact. Select the welding
current intensity on the potentiometer (9) according to the diameter of the electrode (see table
1). Observe the electrode manufacturer's instructions for correct polarity. Cover your eyes and
face with the protection screen and try to brush the tip of the electrode on the piece to be
welded, following a movement as if you were lighting a match; this is the most correct method
to provoke the arc.
WARNING:
DO NOT POINT the electrode on the piece; the liner could be damaged,
making the bow more difficult to draw. Once the arc has been achieved, try to maintain a
distance from the piece, equivalent to the diameter of the electrode used and keep this distance
as constant as possible, during the execution of the welding, remembering that the inclination
of the electrode, in the forward direction, It should be between 20 or 30 degrees.

WARNING:
Always use a tweezer to remove the worn electrodes and dispose of them in
a metal container free of flammable elements. Be sure to use the proper tools and hand
protection when handling parts after they are welded, as the high temperatures that are reached
during the welding process can remain on welded parts, accessories and tools for an extended
period of time. Unplug the machine and collect the cables after the job is finished to avoid
accidents.
