Multi-Process Welders

Most people who have been in a technical profession know the constant need for a variety of tools.  One minute you may need a pliers, then a knife, then a file, then a screwdriver, and once the day is all done, a bottle opener.  This is the reason why multi-tools have become so popular; they combine all of these tools into one. In the world of welding, there is something similar to a multi-tool.  It is known as a multi-process welder. Red-D-Arc carries multi-process welders because we know that one minute you might be self-shielded flux core welding some dirty, ½” thick steel and then the next minute be fitting up 18 gauge aluminum that you need to gas tungsten arc weld.

Red-D-Arc provides a wide variety of multi-process power sources to suit many customer needs.  The Miller XMT is a type of multi-process welder that Red-D-Arc carries.  All XMT variations provide the capability to MIG, TIG, flux core, and stick weld.  The Field Pro series also possesses Miller’s proprietary pulse waveform known as Regulated Metal Deposition (RMD).

This is a pulsed short arc MIG welding process that is excellent at bridging wide gaps that can result from poor fit-up.

Red-D-Arc is aware that multi-process welders aren’t always operated in ideal conditions.  Extreme heat and environments with high amounts of dust can destroy welding power sources. That is why Red-D-Arc provides the EX360.  The “EX” is for extreme, because this power source can handle extreme conditions.  If protection from dust and heat are a concern while using multiple welding processes, the EX360 may be your solution.  The EX360, as well as several other multi-process welders offered by Red-D-Arc, are available in four-pack and six-pack configurations to enable increased productivity.

Submerged arc welding is an excellent process to achieve high deposition rates, and Red-D-Arc has them. However, some applications require additional welding processes besides just submerged arc welding. When this is the case, Red-D-Arc also has multi-process submerged arc welding machines.  The DC1000, for instance, provides end users with the ability to not only submerged arc weld, but also provides stick, MIG, and flux cored arc welding capabilities.

Stud Welders

Some of the most difficult welds to make are those that require the welding of a small diameter to a plate. Gas tungsten arc welding or gas metal arc welding joints such as these require a high degree of operator skill, take a great deal of time, and can be a quality nightmare.  These factors become even more troublesome when the material with the small radius being welded is in the vertical or overhead position. Fortunately, Red-D-Arc provides stud welding equipment that increases productivity, decreases the required operator skill immensely relative to other welding processes, and allows for consistent, repeatable weld quality on materials with small radii.

What is Stud Welding?

Stud welding is a fusion welding process that is commonly used for the joining of small round stock to plate.  The process requires a power source, a stud welding gun, a ground clamp, and the materials that are to be welded.  To carry out the stud welding process, a solid, round piece of metal, also known as a stud, is placed into the stud welding gun.

Depending on the type of stud welding process, a ferrule may be placed around the stud to shield the weld and protect the adjacent base material.  The trigger on the gun is pulled, and a weld is quickly made across the entire faying surface of the stud to the plate on which it is being welded.

Capacitor Discharge Stud Welding

Capacitor discharge stud welding is a very useful type of stud welding.  It uses capacitors to unload a high amount of electrical energy into the weld joint via the stud in an extremely short amount of time (far less than one second).  It is a very clean welding process that requires minimal post-weld attention. It can also weld very thin materials, down to 0.015” thick. Capacitor discharge stud welding is well-suited to weld aluminum, steel, and stainless steel. ¼ inch diameter studs is usually around the upper limits of most capacitor discharge stud welders.  Red-D-Arc provides the Proweld CD-312 stud welder to give you world-class capacitor discharge stud welding capability.

Drawn Arc Stud Welding

Drawn arc stud welding is another very popular type of stud welding.  During this process, an electrical arc is created between the base material and the stud. Drawn arc stud welding also creates a weld joint that joins the entire faying surface of the stud to the plate on which it is being welded.  Although drawn arc stud welds do take longer than capacitor discharge welds, they typically take less than two seconds of arc time per weld. Drawn arc stud welding also typically requires the use of ferrules. These ferrules are ceramic rings that go around the stud in the gun prior to welding.  One advantage of drawn arc stud welding over capacitor discharge welding is that it is capable of welding studs with diameters over 1 inch. The Proweld AC-1850 and the Proweld AC-3000 are two drawn arc stud welding solutions carried by Red-D-Arc to provide customers with extremely fast, high quality stud welds.
