1. The Correct Welding Position
Illustrated is the correct welding position for right-handed people (For left-handed it is
opposite):
a.
Hold the electrode holder in your right hand
b.
Touch left hand to underside of right hand.
c.
Put the left elbow into your left side.
Weld with two the hand whenever possible .This gives complete control over the movements
of electrode. Whenever possible, weld from left to right (if right-hand). This enables you to see
clearly what you are doing. Hold the electrode at a slight angle as shown.

2. The Correct Way to Strike An Arc
Be sure the work clamp makes good electrical contract to the work. Lower your head shield
and scratch the electrode slowly over the metal, and you will see sparks flying. While
scratching, lift the electrode 3 mm and the arc is established.
NOTE: If you stop moving the electrode while scratching, the electrode will stick.
NOTE: Most beginners try to strike the arc by a fast jabbing motion down on the plate.
Result: They either stick or their motion is so fast that they break the arc immediately
3.
The Correct Arc Length
The arc length is the distance from the tip of the electrode core wire to the base metal.
Once the arc has been established, maintaining the correct arc length becomes extremely
important. The arc should be short, approximately 1.5-3.0 mm long .As the electrode burns
off the electrode must be fed to the work to maintain correct arc length.
