3.   Recognize a transformer, rectifier and motor generator
    type welding machine.
4.   Explain the principle of the AC and DC welding current.
5.   Identify components of gas metal arc welding equipment.
6.   Set up and place in operation oxy-acetylene, arc and gas
    metal arc welding equipment.
7.   Differentiate between plain carbon steel, alloy steel,
    ferrous and non-ferrous metals.
8.   Produce a sample butt joint, lap joint, fillet weld and
    braze welded fillet using the oxy-acetylene welding process.
9.   Produce a sample of free hand flame cutting and straight line
    beveling and piercing.
10.  Produce a sample of stringer beads, padding, weaving in the
    flat position, a multipass filet weld in the horizontal
    position, a lap joint and a fillet weld in the vertical down
    position using shielded metal arc welding.
11.  Produce a sample lap joint, fillet weld using the gas metal
    arc process.
12.  Identify filler metals for oxy-acetylene and arc welding.
13.  Recognize a light medium and heavy flux coated arc welding
14.  Achieve a passing score (75%) on written examinations.
15.  Achieve a passing score (75%) on manipulative skill
    development demonstrations.
16.  Based on subsequent repeats, student will develop increased speed,
