This HD video covers the final assembly and welds that make up the “cube”. Note the positions and options available for practicing your oxy-acetylene gas welding with a cube of sheet metal.
The “cube” is a good final exercise project for gas welding. 16-gauge sheet metal sides, top and bottom provide challenges at flat, vertical and overhead welding positions.
The use of practice sheet metal is more affordable. ER70-S2 rod in 1/16″ and 3/32″ is also inexpensive. When you practice, use new or clean metal to assure good results. Make the most of the metal, gas and filler.
Gas welding is as viable as any other fusion welding method. These welded beads have the stamina, quality and appearance of MIG or TIG. Light gauge metal can be difficult to weld and control heat. Gas welding proves as user friendly as any other form of fusion welding—arguably easier than some!
