6.0 WELDING TECHNIQUE
1 Plug your welder into the correct socket and switch on using
the ON/OFF switch (Item B). NOTE (for models 80E, 95E and Easi
Arc 150): If the machine stops at any time and the ON/OFF switch
lights, the thermostat has intervened. Wait for a few minutes while
the transformer cools down and when the ON/OFF switch goes out
again welding can begin.
2 Particularly for beginners, the most difficult aspect of the arc
welding process is that of striking an arc. We strongly recommended
that you practice on pieces of scrap metal to get the feel of
the operation, before you start on an actual welding job.
3 Hold the electrode about 3/8" from the workpiece and at an
angle of about 70 degrees to 80 degrees to the work surface; take
care not to accidentally touch the workpiece until you are ready to
begin.
4 Holding the welding mask close to your face, give a short
stroke with the electrode on the workpiece. As soon as the arc is
struck, lightly withdraw the electrode from the workpiece to leave a
tiny gap of around 1/16". The current will flow across the gap with a
crackling noise and brilliant arc. Continue to weld in one direction,
maintaining the small gap as you go. At the end of the run, just
withdraw the electrode fully from the workpiece.
NOTE: When you strike an arc be sure to withdraw the electrode
fairly swiftly to leave the 1/16" gap, otherwise the electrode will weld
itself to the workpiece. Should this happen give the electrode a short
sharp jerk to free it and, if necessary strike the arc again.
5 Inspect the job carefully. With a correct combination of rod
size and amperage setting, the area of the weld should be a com-
plete fusion of the electrode metal being joined. Slag forming on
the surface should be chipped away with a hammer.
