Advanced Weld Cameras: The Rental Option

Posted by Eric McCarron on Tuesday, November 19, 2013 @ 06:12 PM

The Xiris XVC-O Weld Camera features High Dynamic Range imaging, a technology that enables Weld Cameras to provide manufacturers with productivity and quality gains never before possible with cameras.

High Dynamic Range imaging combines advanced camera and image-processing technologies to give operators a clear, real-time image of the welding process, including both the super-bright arc region and the dark surrounding background

Because operators using a Weld Camera without this capability have to periodically adjust lighting in order to clearly see all the detail of the weld, High Dynamic Range imaging results in increased welding output. And because the images are of such high quality, operators have greater visibility into the process than possible with traditional Weld Cameras—leading to improved quality control.

But as with any new technology, there is an initial cost for taking advantage of it. The expense of purchasing an XVC-O (or XVC-S for Sub Arc Welding) is a small price to pay for the long-term benefits; nonetheless, it is a capital investment—and it’s not always the right time to purchase an asset, no matter how attractive its potential return on investment.

Fortunately, as with most commercial equipment, Xiris Weld Cameras can also be rented, allowing companies to pay monthly payments rather than a lump cash payment, thereby preserving working capital for other business needs. (And the rental programs can typically be structured to allow for rent-to-own.)

Red-D-Arc Adds Xiris                                                                                                     

As part of our effort to make our Weld Cameras easily available for rental, Xiris has recently partnered with Red-D-Arc Welderentals, which the Rental Equipment Registry dubbed as the “industry’s leading welder rental specialist” in its 2013 list of the top 100 equipment leasing companies (Red-D-Arc ranked #22 overall).

Red-D-Arc is leasing Xiris Weld Cameras with advanced camera technology.On its website, Red-D-Arc is now featuring both the XVC-O and the XVC-S. Red-D-Arc also has the XVC-S installed on a manipulator it's exhibiting at Fabtech 2013, currently underway in Chicago.

Our Weld Cameras are housed in an extremely rugged enclosure, and when rented through Red-D-Arc, they are sent out in a sturdy Pelican case, making them easy to return in one piece.

If you’d like to gain the benefits of the XVC-O or XVC-S without the capital commitment of a purchase, leasing through Red-D-Arc could be the path for you.


Advanced Weld Cameras can add substantial value to automated welding operations—and that value can be gained through purchasing or leasing. You don’t have to spend a lot of cash to begin reaping the benefits of this exciting technology now.

Using a Weld Camera to Help Select Shielding Gas

Posted by Eric McCarron on Tuesday, April 30, 2013 @ 10:47 AM

Shielding gas is the inert or semi-inert gas that is pumped into a welding process to protect the weld area from atmospheric gases such as oxygen, nitrogen, and water vapor that could reduce the quality of the weld or make the welding more difficult. 

The wrong selection of a Shielding Gas can lead to a porous, cracked, or weakened weld, as well as increase the amount of weld spatter. The better Shielding Gases, however, can improve the weld bead shape and weld bead penetration, while reducing the amount of fumes generated.

By monitoring the look and appearance of a Shielding Gas, a welding operator can select a Shielding Gas that dramatically increases the welding speed, quality, and deposition rate of a welding process.

GMAW Process Showing Shielding Gas


Traditionally, a method of monitoring Shielding Gas has been to listen to the arc to hear the crackle of the weld process. This was never an exact process, as the best way to monitor shielding gas is with visual means. 

Why Monitoring Shielding Gas Is Important

Small, subtle changes in the chemistry of the Shielding Gas can make significant changes to the weld process. The chemistry affects the variations in arc and weld bead characteristics, which in turn have dramatic impact on the resulting weld.

For GMAW of carbon steel

Very different weld outcomes are generated depending on whether a mixture of Argon with CO2, Argon with O2, or a tri-mix of Argon\CO2\O2 is used as the shielding gas. For example, using a shielding gas rich in Argon with a small amount of Oxygen and CO2 (i.e., between 2% and 8%) works well in GMAW Spray and Short Circuit transfer modes, where the welding can be performed at lower voltages than if an Argon/CO2  mixture was used.

For GMAW of stainless steel

Mixtures rich in Helium (>50%) with small concentrations of Argon and CO2 establish a stable weld arc with good cleaning in GMAW Short Circuit transfer mode.

When using Argon-rich (>50%) shielding gas for GMAW Spray transfer mode, the addition of CO2 increases weld penetration, while adding helium improves wetting and flattens the bead profile.

Weld Cameras Enable Effective Monitoring

Using a Weld Camera and a remote display console to visually monitor the impact of gas mixtures, while also monitoring the wire type and wire feeding characteristics, greatly improves the ability for the operator to monitor and adjust the parameters for optimum performance.

The Weld Camera adds the ability to see the detail of the arc and monitor the impact of the shielding gases in real time, to determine the optimum welding procedure for your particular situation.    

The speed, weld penetration, arc configuration and weld spatter characteristics are all visible to the operator using a Weld Camera, so that the operator—at a safe, remote distance looking at the display monitor—can determine how well the shielding gas is performing.
