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 is 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.

Powerful Clean Wet Media Blasting that Removes Almost Any Coating

If you’re trying to remove old paint, hardened epoxy, corrosion, rust or scale you want a powerful cleaning solution that’s easy to use. Wet Media Blasting using crushed glass is one of the toughest most reliable methods available.

Built Tough, Easy to Use

The Clearblast 150 wet media blaster provides powerful wet blasting in a portable package. Ruggedly built to take on the toughest blast cleaning jobs, this machine can provide up to 120psi of cleaning power for over an hour straight. The intuitive control panel is easy to understand and first-time users can get set up and start blasting within minutes. Stainless steel piping on a hard steel frame with a powder-coated finish makes this machine an excellent choice for harsh environments and repeated transport and use.

The Wet Blasting Process

1. Water is supplied by the on-board tank or standalone trailer. (uses roughly 1 pint per min.)
2. Abrasive media is added to the hopper
3. Compressed air delivers a stream of wet abrasive media to the cleaning surface like a hail of darts

Wet Media Blasting using crushed glass is one of the toughest, cleanest blast cleaning methods available.

An Excellent Alternative to Sandblasting

Dry blasting methods throw particles against a surface, pulverizing coatings and creating a lot of airborne particles which can be a health hazard and a pain to clean up. It can also damage the substrate, removing materials and compromising surface integrity. Substantial containment and cleanup are involved. Wet Blasting, on the other hand, eliminates more than 90% of airborne dust, uses far fewer blast media and is one of the safest, cleanest, greenest blasting methods available.

Dustless Blasting?

Many blast cleaning systems claim to be “dustless” but what we are really talking about is the reduction of airborne dust particles. If you’re using blast media and removing coatings, you’re going to have some residue. Wet media suppresses airborne dust and requires far less clean up than other blasting methods. Until someone invents a blaster that destroys matter, there’s always going to be some kind of residue leftover from a blasting job.

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.

Top 3 Advantages of using a pulsed-MIG Welder

When MIG welding was first invented, it used a constant voltage source of electricity for the arc.  While this method is still used today, the invention of pulsed MIG (or MIG pulse) welding has allowed welders to realize several advantages over conventional MIG welding, several are listed below:

  1. Pulsed MIG can be used to weld thin materials.  Conventional MIG welding runs at a constant amperage whereas pulsed GMAW welding runs a peak and background amperage. The constant switching between these two amperages enables the welder to put out a lower overall heat input into the material.  This helps prevent blowouts on thin materials.
  2. There is less spatter than conventional MIG welding.  Pulsed MIG welding uses a peak electrical currents to cleanly burn the wire off at a high amperage.  It also employs a lower background welding amperage immediately after the peak electrical current to prevent the interaction of the electrical arc and the wire from becoming unstable.  This ultimately results in a reduced amount of spatter.
  3. MIG pulse welding is excellent for out of position welding.  At the same voltage and wire feed settings, conventional MIG tends to have a weld puddle that is larger and more fluid than that of pulsed.  MIG pulse welding has more controllable puddle that prevents it from falling out when gravity is a concern during out of position welding. Furthermore, the reduced amount of spatter than can be achieved with this method makes it safer for the welder to perform the out of position operation.
