• The welding point on the workpiece should be free of rust and paint.
Choose the appropriate electrode according to the size and material
of the workpiece.
• For beginners, the first difficulty is priming the arc. For best results
proceed as follows:
- Test the current intensity and the electrode on a piece of
scrap material.
- Hold the electrode approximately 2 cm above the start of the joint
and hold the face shield in front of your face. Touch the workpiece
with the electrode and stroke it repeatedly on and off the workpiece
to start the arc, as if you were striking a match. It may occur that the
breakaway movement of the electrode is not quick enough, which
can mean that the electrode sticks to the workpiece. Remove the
electrode with a firm lateral jerk. (If this does not work, release the
electrode from the clamp on the electrode holder, then use pliers
or tongs to remove the electrode from the workpiece).
- Watch the arc through the lens in the face shield and keep the
arc length approximately 1 – 1.5 times the diameter of the electrode.
The arc length is very important as it has an influence on the welding
current and welding voltage.
- Incorrect current intensity produces a poor quality, weak joint.
- Hold the electrode at an angle approximately 70° – 80° to the
workpiece in the direction of advancement. If the angle is too large,
the slag can penetrate the joint; if the angle is too small, the arc
flutters and sprays molten metal. In both cases, a weak, porous joint
is produced.
- Ensure that the arc length remains constant by feeding the electrode
continuously towards the workpiece as you progress down the joint.
At the end of the joint; pull the electrode gently downwards away
from joint to avoid producing a porous end crater.
- Wait until the joint has cooled completely before removing the slag.
If you wish to continue welding a joint after taking a break, the slag at
the end of the joint must be removed first. Prime the arc in the joint
and melt the electrode at the point where the two joints meet.
