Plasma welding is not a new process to the industry, but only in the past few years has it gained significant acceptance. Until recently, the process was considered exotic and difficult to understand. This was mainly due to the applications it was being adapted to. PLASMA NOW HAS PROVEN ITS VALUE IN THE AREA OF HIGHLY REPETITIVE AUTOMATED WELDS. THE PROCESS PROVIDES INCREASED RELIABILITY AND REPEATABILITY TO MEET TODAY’S HIGH STANDARDS OF PRODUCTIVITY.
It is most frequently used as an alternate to the gas tungsten process (GTAW) . For most applications, the plasma arc process offers increased electrode life, reliable arc starting, improved arc stability, better penetration control and reduced current levels. In some cases, plasma offers increased travel speeds, improved weld quality, and less sensitivity to operating variables.
Stick welding is a simple yet versatile, inexpensive and portable welding process. Flux coated welding rods are used, eliminating the need for bottled shielding gas like that used in MIG welding or TIG welding.
Stick welders are ideal to use when welding outdoors and/or welding objects that are rusty or dirty. Most common metals and alloys can be joined using a stick welder.
TIG (tungsten inert gas) welding is used to make precise, critical welds when joining metals such as mild steel, aluminum, or stainless steel.
TIG welding is a two handed process (one hand holds the torch while the other feeds filler metal) and commonly involves a foot pedal or fingertip remote to control the arc voltage while welding. Like MIG welding, a shielding gas (typically argon) is required.
MIG (Metal Inert Gas) Or Gas Metal Arc Welding (GMAW), is a welding process in which a consumable metal electrode is used to produce the electric arc to join the metal pieces together in the environment of a shielding gas. Shielding gas protects the weld from atmospheric contamination. Constant voltage, direct current power source is used to produce the arc.
These welders are capable of performing MIG, Stick, TIG, and Flux-Cored welding processes. Find the one that’s right for your application.
