EX360 FieldPro Multi-process Welder

ArcReach® technology is an investment that results in a lot of time saved during welding operations.  With most welding equipment the operator needs to walk back and forth to adjust output voltage – sometimes over hundreds of feet – multiple times during a job. This results in hundreds of wasted hours and thousands of lost dollars over the course of a large project.

ArcReach technology enables welders to adjust the voltage settings right at the point of welding

ArcReach technology enables welders to adjust the voltage settings right at the point of welding instead of walking all the way to the power source and back.  Even worse, if the voltage settings are “just good enough”, the operator might not bother making the trip, resulting in lower quality welds.

How Does Arc Reach Work?

With ArcReach®, the digital signal carries voltage information via the weld cables. The connection happens automatically.   The ArcReach software in the power source receives the signals it receives from the remote accessory or wire feeder and adjusts the output as indicated by the operator.

New Red-D-Arc Welders With ArcReach®

Red-D-Arc is pleased to announce the launch of our own line of equipment enabled with ArcReach®technology.  The EX360 Fieldpro is an excellent machine for welding pipe in the field, working in shipyards or working across large distances and heights in the construction industry. Our D624K HO Diesel Engine Welder features infinite arc control which enables welding arc characteristics to be adapted for specific welding applications using stick welding, MIG and flux-cored welding techniques.

ArcReach Welding Accessories

We also carry the arc reach components needed to complete your ArcReach® enabled welding set up. The ArcReach® Suitcase 12 Wire Feeder is compatible with all ArcReach® enabled products and enables all the welding adjustments to be made at the point of welding.  The portable ArcReach® Stick-TIG Remote automatically changes to Stick mode if electrode positive polarity is detected or TIG mode when if electrode negative polarity is detected eliminating the need to walk back to the power supply.

Welders will benefit with more arc-on time and improved weld quality. Not only that, there won’t be extra control cables cluttering up the worksite, creating a trip hazard.  Faster, better, safer welding. ArcReach® technology is an investment you can’t afford to pass up.

What are the differences between types of tungsten electrodes?

To begin with, different electrodes have different colored bands that are used to identify them.  However, there are several other important differences to consider when selecting a tungsten.  Here some of the various types with the respective characteristics:

EWTh-2:  2% thoriated tungsten.  The EWTh-2 tungsten electrode is color-coded with a red band.  It is known for its durability, ability to withstand high currents, and excellent arc starts.  It is primarily welded using a negative polarity and direct current. It does not have great characteristics when welding with AC.

EWLa-2: 2% lanthanated tungsten.  The EWLa-2 tungsten electrode is color-coded with a blue band.  It is known for its excellent arc starting ability, excellent current carrying ability, and can withstand many arc cycles.  It can be welded as the negative electrode using direct current or with alternating current.EWP:  Pure tungsten electrode.  EWP is color-coded with a green band.  It has excellent arc stability. It is almost exclusively used with alternating current.  Tungsten emission is more likely with a pure tungsten electrode when compared with other alloyed tungsten electrodes.

EWCe-2:  2% ceriated tungsten.  EWCe-2 tungsten electrode is currently color-coded with a gray band, although in the past it was color-coded with an orange band.  It is quite similar to EWLa-2 in that it has excellent current carrying ability, excellent arc starting ability, and can last through many different arc start and arc termination cycles.

9 Tips to Help Prevent Wire Feed Problems in MIG and Flux-Cored Welding

How do I prevent wire feeding problems when using the MIG welding (GMAW) or flux-cored arc welding (FCAW) process?

Wire feed problems can be caused by a variety of circumstances.  Some of the most common reasons for wire feeding issues include:

  1. Drive roll tension:  The drive rolls that push or pull the wire through the system have a tension that is either too great or too little.  Adjust the spring pressure until the tension is appropriate.
  2. Drive roll size: The drive rolls may be the wrong size.  For instance, if 1.3 mm drive rolls are being used to move 0.9 mm wire, slipping will most likely occur.
  3. Drive roll type:  Some wire requires specific kinds of grooves for optimal feeding.  Flux-cored and metal-cored arc welding wires typically require V-groove drive rolls that are knurled.  Aluminum wires require a smooth U-shaped groove.
  4. Drive roll condition:  Worn drive rolls will be ineffective at moving a wire through the system.
  5. Liner size:  If a liner is too small for the wire it will not feed.  If the liner is too big, the wire may have too much freedom to twist inside of it, causing an unpredictable feed.
  6. Liner type:  For most wires, steel liners work excellent.  However, some wires, such as aluminum, require a nylon liner to help ensure proper feeding.
  7. Liner condition:  A worn liner will be detrimental to wire feeding.  Replace the liner if it is worn or damaged.
  8. Contact tip size:  A proper contact tip size should be used.  If the tip is too small, the wire will not feed; if the tip is too large, wire feeding and electrical conductivity may be negatively affected.
  9. Wire condition:  Not all wire manufacturers put out the same quality product.  Some wires may have thin and thick spots as well as lubricants that can cause poor wire feeding.

Miller 252 Welder The Millermatic 252 —sometimes referred to as the Miller 252— is an extremely popular and easy to use welder. You only need to see the reviews quoted on Miller’s product site to see how much those who use this welder like it. It can be used for metal fabrication, maintenance and repair, farm and home use as well as light industrial applications.
Capable of MIG (GMAW), Wirefeed, and Flux-Cored Welding (FCAW),this machine employs Active Arc Stabilizer technology which creates consistent power output resulting in better quality welds. The push/pull gun connects directly to the unit with no extra module required in between.
Review - millermatic 252 welder
The unit detects the gun automatically and recalls the voltage, wire feed speed and timer of the active gun. There’s a panel on the front of the unit with a quick-reference parameter chart so you can quickly apply the correct settings for the consumables you are using. This welder has the highest output in its class (250 A at 28 VDC) allowing longer welding times on high-end applications. This is a very popular unit, praised for its ease of use by people who are learning to weld, hobbyists and others for whom welding is only one of many tasks they perform in a day. One user says that he taught his entire family to weld using this machine, including his 57 year old mother. Feature rich, well thought out, and easy to use, you would be hard pressed to find a better welder than the Millermatic 252.
