Plasma Arc Welding

Plasma Arc Welding

Plasma arc welding (PAW) is an arc welding process that utilizes an electric arc--formed between an electrode and a workpiece.

A deep, narrow penetration is often possible with great accuracy.

Plasma Arc Welding Items of Interest Hobart 500548 Airforce 500i 115/230 Volt Plasma Cutter The Hobart Air Force 500i plasma cutter features a multivoltage plug (MVP) that allows user to connect to common 120V or 230V power receptacles without tools. U.S.A. Cutting Thickness (in.): up to 5/8, Volts: 115/230, Amps: 27, Duty Cycle: 35% @ 27 Amps, Pilot Arc: Yes, Plasma Gas Flow/Pressure: 4.5 CFM @ 60 PSI, Clamp Cable Length (ft.): 16.5, Power Cord (ft.): 10, Cart: No, Dimensions L x W x H (in.): 14.25 x 8.25 x 11.25 Steele Products SP-WP018 120 Amp Plasma Cutter with 18.5-Foot Cable and Torch Lead TIG Welding Basics (DVD) TIG welding has been long recognized as the premiere welding process, which can make beautiful, strong welds on nearly any metal. In this easy-to-follow program, Ron Covell covers the basic processes used for TIG welding, covering proper machine setup, joint preparation, electrode selection and preparation, torch technique, and perhaps most importantly, what to check for when things go wrong! This thoughtful description of the welding process, coupled with the close-up photography that brings the action into clear view makes the seemingly difficult process of TIG welding easy to understand. Advanced TIG Welding (DVD) This program covers many advanced topics in TIG welding, including welding chrome moly steel, stainless steel, aluminum, magnesium, bronze, copper, and titanium. You'll also learn how to weld castings made from aluminum, magnesium, and bronze. Clear guidelines are given for using the pulse and waveform adjustments that many new welders have, along with great practical advice on machine setup, joint preparation, and weld finishing. Ron's clear and detailed instructions are easy to follow, and the striking close-up photography shows you exactly what to look for as you weld! 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. This Torch Cutting DVD 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. Ramsond CT520DY 3-IN-1 DUAL VOLTAGE 110V/220V 50/60HZ MULTI FUNCTION INVERTER PLASMA CUTTER + TIG WELDER + ARC/MMA STICK WELDER: 50 AMP PLASMA CUTTER + 200 AMP TIG WELDER + 200 AMP ARC MMA STICK WELDER Ramsond introduces the 4th generation of its CT520DY. CT520DY is a 3-in-1 multifunction cutting and welding machine. It is a 50 Amp plasma cutter, a 200 Amp DC (Direct Current) TIG welder and a 200 Amp ARC/MMA stick welder. It is dual voltage 110V/220V and dual frequency 50/60 Hz. It is equipped with DIGITAL AMP DISPLAY, INTEGRATED PRESSURE GAUGE, FOOT PEDAL FUNCTION and FOLDABLE INSULATED HANDLE. It uses the most reliable high frequency V-MOSFETs by TOSHIBA along with PWM (Pulse Width Modulation Processor) which help deliver a constant, concentrated and precise current to the cutting/welding surface. Regardless of your training, you can achieve smooth, clean and uniform cuts (1 inch) and weld a wide range of surfaces and material (e.g. stainless steel, carbon steel, alloy steel, copper, brass and other conductive material) with minimal heat input and without distortion of metal. CT520DY is easy to use by the do-it-yourself user, while fully accommodating of the demands of professional operators. It has five controls; the ON/OFF switch, Amperage Control Knob, the Post Flow Knob, Function Selector and the foot pedal ON/OFF switch. It has an integrated air pressure gauge in the front panel of the unit, as well as a large digital display that conveniently displays the current (Amps) setting of the unit. Note: This is a DC (Direct Current) TIG Machine. For aluminum welding AC (Alternating Current) is recommended. Each Ramsond CT520DY comes fully equipped with all accessories: TIG Torch, Plasma Torch, ARC/MMA Electrode Clamp, Air Regulator/Filter, Argon Flow Meter, Set of Consumables for the plasma and TIG torches, and Ground Clamp. Plug is not included. It comes with a 1 year Limited Warranty (Parts and Labor). The consumables are readily available both through Ramsond and third party sellers and are reasonably priced. Welder's Handbook, RevisedHP1513: A Guide to Plasma Cutting, Oxyacetylene, ARC, MIG and TIG Welding A newly-updated, state-of-the-art guide to MIG and TIG arc welding technology. Written by a noted authority in the field, this revised edition of HP's bestselling automotive book-for over 20 years-is a detailed, instructional manual on the theory, technique, equipment, and proper procedures of metal inert gas (MIG) and tungsten inert gas (TIG) welding. TIG and Plasma Welding: Process Techniques, Recommended Practices and Applications This book provides designers, welding engineers and metallurgists with the essential information for understanding the welding operation and for applying the processes in production.
