Striking the arc
1. Scratch the work piece (1) with the end
of electrode (2) to start the arc and then
raise it to a gap of 1/8" between the rod
and the work piece
2. Maintain the constant gap between the
welding rod and the work piece during
welding.
Note: If the gap is too narrow, the rod will stick
to the work piece. If the gap is too wide, the
arc will extinguish.
3. Gently rock the welding rod back and forth
when the rod sticks to the work piece, to
separate them.
Note: A stuck electrode will cause a short circuit
and the thermal overload protector will shut the
welder OFF.
4. Make sure the arc is accompanied by a
crisp cracking sound, as it indicates a
proper arc.
5. Move the electrode (1) downwards along
desired direction to lay a weld bead
(fig 2M).
DANGER!
Potential hazard that will result in serious injury or loss of life.
• Do not expose self to a welding arc.
• Do not weld without adequate protection.
• Wear recommended safety equipment and clothing before welding.
