3 Oxy-fuel Cutting Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES When you are cutting steel or ferrous metals that are ½” or thicker, Oxy-fuel cutting is the best method to use.

4 Oxy-fuel Cutting Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES The Oxy-fuel torch heats the metal to the melting point of the metal. The air- blast trigger is mashed and a blast of oxygen pushes the molten metal from the cut.

5 Oxy-fuel Cutting Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES The Oxy-fuel torch leaves a layer of dross (slag) on the cut edges.

6 Select a letter and use a soapstone to trace around the letter. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

7 Make sure the letter is drawn completely. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

8 Light the torch and adjust it to cut. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

9 Begin heating and cut the lines out. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

10 Cut the inside of the letter first, then the outside. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

11 Make sure the metal is cut completely. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

12 The letter will still be connected by the dross in the cut. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

13 Use pliers to break the dross and remove the letter. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

14 The letter has a rough edge because of the dross. It will need to be grinded and filed. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

15 Carefully use a grinder on the surface of the letter. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

17 Use a bench grinder to smooth the edges. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

18 Use a file and a vise to smooth the edges that you can not grind down. Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES

20 Plasma Cutting Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES This method of cutting can be used on metal less than ½ inch. The metal can be ferrous or nonferrous because the plasma is used to heat the metal, then the super hot gasses blast the metal from the cut.

21 Plasma Cutting Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES The edges of a plasma cut are smoother than that of an oxy-fuel cut.

22 Oxy-fuel vs. Plasma Cutting Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES The plasma-cut edges are smoother. This means less cleaning of the piece for a cleaner appearance.

23 Hand-held Plasma Cutting Copyright © Texas Education Agency, All rights reserved. STORAGE BOX TITLE OF DRAWING NAME DATE PAGE 4 6_6_ ALL FOLD LINES = ⅜ 10 ½ 12 _ ⅜ ½ ½ ½ ALL MEASUREMENTS ARE INCHES Hand-held plasma cutting will be done basically the same way, but will have less dross.
