1) OXY-ACETYLENE WELDING DVD:
Oxy-acetylene welding is not only an excellent method of joining thinner gauge metals, it’s also the best "first step" to understanding the fundamentals of welding.
WMC’s Oxy-Acetylene Welding DVD covers equipment set-up, adjusting the regulators, lighting the torch and adjusting the flame. We even sneak in a little theory on why a neutral flame purges oxygen from the weld area.
Beginning with starting and moving the molten puddle, then adding filler metal, close-up demonstrations with slow motion and inserted arrows point out exactly where to watch the molten weld puddle.
Close-up video of the actual welds, with detailed explanations, demonstrates the characteristics of the molten metal and weld buildup for welding in the flat, horizontal and vertical positions. Metal preparation, joint fit-up and welding techniques are demonstrated for butt, lap, T and corner joints, focusing on penetration and amount of weld buildup.
Approximately 42 minutes.
An excellent DVD for beginners.
2) FLUX CORE ARC WELDING DVD:
An introduction to the Flux Core Arc Welding process, covering both self shielded and gas shielded flux cored welding wires.
Self Shielded Flux Core welding wires provide a wire feed process that can be used inside or outside of the shop. With moderate deposit rates and lower voltage requirements, self shielded flux core is probably the easiest type of welding to learn and use, and the general purpose self shielded welding wires are a good choice for the smaller wire feed welding machines.
Gas Shielded Flux Core is the most common semiautomatic wire feed process used in the welding industry for heavy fabrication. High deposit rates, good weld fusion, and ease of operation also make gas shielded flux core an excellent wire feed process for the in shop repair of farm and construction equipment.
Flux Core Arc Welding focuses on fundamental welder skills. Extremely close-up video of actual welds, with detailed explanations, demonstrate how the voltage and wire speed settings, electrode extension, gun angle, and travel speed affect penetration, the shape, and the size of the weld. Also included are weld joints, metal preparation, and joint fit-up.
Flux Core Arc Welding also provides a "working knowledge" of constant voltage power sources, wire feed units, and the unique characteristics of flux cored welding wires. Understanding the technical aspects of FCAW is an important part of setting up the equipment to provide the correct amount of weld, with good penetration and weld fusion.
Approximately 58 minutes.
Great for beginners and intermediate welders.
3) GMAW (MIG) WIRE FEED WELDING DVD:
Wire feed has the reputation of being "real easy". It might be more accurate to say that it’s easier to get started. While the welding machine does feed wire and regulate the current, the welder still needs to set up the equipment and control the molten weld deposit.
Gas Metal Arc Welding, which is often referred to as MIG, is one of the most widely used wire feed processes. Whether you’re headed into the welding industry, or out into your home shop, GMAW Wire Feed Welding presents both the technical aspects and the welder skills needed to consistently make successful welds on carbon steel.
Close up video of the actual welds, graphic illustrations, and detailed explanations provide a practical knowledge of the welding machine, filler wires, shielding gases, and metal transfer. Step-by-step close-up demonstrations cover the fundamentals of all-position Short Circuit Transfer.
Included are wire extension, wire feed gun movement, direction of travel, travel speed, and adjusting the voltage and wire speed for the optimum metal transfer. Extremely clear video of the actual welds demonstrate the flat, horizontal, vertical, and overhead welding positions, plus weld joints, metal preparation, and joint fit-up.
In depth, yet easy to understand explanations and demonstrations make GMAW (MIG) Wire Feed Welding great for the beginner.
Approximately 45 minutes.
An excellent video for the beginner or intermediate welder.
4) TORCH CUTTING (OXY-ACETYLENE) DVD:
Cutting torches are found in many types of shops and job sites, and the better you learn to handle the torch, the more versatile it becomes.
WMC’s Torch Cutting video is an in-depth guide to using the cutting torch effectively. Included are equipment set-up, with demonstrations of adjusting the regulators, and lighting and adjusting the torch. Demonstrations show how to make straight cuts, explaining gas pressure settings, starting the cut, speed of progression, where to watch, restarting in the kerf, slag and metal preparation.
Detailed explanations with close-up demonstrations include cutting thick metal, thin metal, making cutouts, using circle burners, cutting through two pieces of metal, vertical cuts and using straight edges.
Also included are demonstrations of practical cutting situations like cutting off bolt heads, burning round bolt holes, cutting pipe, solid round stock, cutting apart T-joints, and cutting off a nut while saving the threads to reuse the bolt!
Approximately 45 minutes.
A great video for everyone interested in using a cutting torch, with more than 40 close-up demonstrations.
