<noinclude></noinclude><section end=req2 /></b>

<b>3. <section begin=req3 /><noinclude></noinclude>While blindfolded, demonstrate ability to hook up an entire oxyacetylene kit, including tanks, gauges, hoses, and torches, and light the same.** 
<noinclude></noinclude><section end=req3 /></b>

<b>4. <section begin=req4 /><noinclude></noinclude>As per your instructor's directions, weld two mild steel test plates (1/8 inch x 1 inch x 8 inches) (0.3 cm x 2.5 cm x 20.3 cm) in horizontal, and vertical positions. 
<noinclude></noinclude><section end=req4 /></b>

<b>5. <section begin=req5 /><noinclude></noinclude>Use a cutting torch and demonstrate your skill by making one 12 inches (30.5 cm) straight-line cut, one circle cut of at least 3 inches (7.6 cm) in diameter and one 3 inch (7.6 cm) star cut. The cuts are to be made on mild steel plate at least 1/4 inch (0.6 cm) thick. 
<noinclude></noinclude><section end=req5 /></b>

<b>6. <section begin=req6 /><noinclude></noinclude>Demonstrate your ability to braze a cast-iron object with at least 1/4 inch (0.6 cm) double bevel butt weld 2 inches (5 cm) long. 
<noinclude></noinclude><section end=req6 /></b>

<b>7. <section begin=req7 /><noinclude></noinclude>Explain the safety precautions and safety equipment normally used in electric welding in relation to eyes, hands, and exposed skin areas. Why should the tank valves never be oiled? 
<noinclude></noinclude><section end=req7 /></b>

<b>8. <section begin=req8 /><noinclude></noinclude>Explain the difference between oxyacetylene and electric arc welding. 
<noinclude></noinclude><section end=req8 /></b>

<b>9. <section begin=req9 /><noinclude></noinclude>Demonstrate ability to select from an electrode guide the proper amperage and electrode for various types and thicknesses of metal. 
<noinclude></noinclude><section end=req9 /></b>

<section begin=challenge />
<b>10. <section begin=req10 /><noinclude></noinclude>Demonstrate ability to weld flat, vertical, horizontal, and overhead on (1/8 inch x 1 inch x 8 inches) (0.3 cm x 2.5 cm x 20.3 cm) mild steel test plates. 
<noinclude></noinclude><section end=req10 /></b>
<section end=challenge />

<b>{{Localize|Note}}: <section begin=reqNote /><noinclude></noinclude>An instructor is a must. Welding is a very critical and serious skill to learn and is not a home-type course. Welding essentially takes the place of bolts and rivets, and if not properly done, is most dangerous. Example: A trailer hitch not properly bonded, or machinery exposed to the strain of pull or weight, is an invitation to disaster. 

Note: <nowiki>**</nowiki>This requirement demonstrates one's skill in working in darkness, such as in an emergency. All acetylene connection threads are left-handed, while all oxygen connection threads are right-handed.
