Field of Dreams

High Tech Welding has gained 25 to 30 percent in productivity in its field repairs since it began using the Multimatic 200 a year ago. The portability and multiprocess capabilities of the unit are at the heart of those benefits.
Take a look at how Wisconsin fabricator High Tech Welding uses a portable all-in-one multiprocess power source to gain versatility and increase their welding productivity by 25 to 30 percent on field repair and fabrication jobs.

What You Must Know About Robotic Welding

This reamer cleans the nozzle of dirt, debris and spatter during routine pauses in the robotic welding operation to help prevent shielding gas coverage loss that could lead to weld defects, expensive rework and lost productivity. This also helps the front-end consumables last longer, meaning less downtime for changeover and less expense for replacements.(Click on photo to enlarge it)
Lloyd Steed of Tregaskiss identifies the key factors that must be understood to manage a profitable and productive robotic welding operation that really gains a competitive edge and makes the most out of its investment.

What You Must Know About Pulsed MIG Welding of Aluminum

The Invision 352 MPa used by Greenheck welders features built-in Pulsed MIG programs for common 4000 and 5000 series aluminum wires ranging in diameter from .035 in to 1/16 in, as well as many of the other alloys (steel, stainless steel, silicon bronze, copper, nickel) found in their products.(click on photo to enlarge it)
Three manufacturers share their tales with Mike Vandenberg, Jeff Herb and Chris Roehl of Miller Electric about pulsed MIG welding of aluminum and how new technologies have made the process more viable in their operations by reducing distortion and rework, improving productivity and standardizing wire size.

Checking the Pulse of Welding Inconel

Inconel, as many nickel-based alloys, is highly susceptible to cracking and warping – especially thin structures. As such, controlling heat input to the part is important, as well as controlling arc starts, providing proper shielding gas protection and averting crater formation at the end of the weld.(Click on photo to enlarge it)
Whether TIG welding in the aerospace industry or MIG welding overlay in a plant environment, successfully welding Inconel can depend on your pulsing capabilities and other new features made possible with modern equipment. Dave Almy and Mark Kadlec of Miller Electric explain why.

Push or Drag Angle with GMAW to Reduce Porosity – The Answer Is: It Depends

A dragging technique causes more of the arc energy to be focused on the weld puddle compared to when a forehand, or push technique, is used. This provides time for the trapped gases within the weld to bubble out before the puddle has solidified.(Click on top two photos to enlarge them)
Lesson Learned: This analysis shows how one must be careful of getting locked into welding a certain way only because that’s the way it has always been done.

Highly Versatile Aluminum MIG Welder and More

The Millermatic 350P Aluminum synergic welding system from Miller Electric gives the operator the first-of-its-kind flexibility with synergic “one knob” control in both Pulsed MIG and MIG operation. The synergic connection means the Millermatic 350P Aluminum automatically adjusts voltage and amperage when the operator adjusts wire speed on the gun. This saves time and improves quality because the welder can react in real time to changing joint profiles and positions without having to stop welding and go back to the machine.
The Millermatic® 350P Aluminum MIG welder from Miller Electric is the first dedicated aluminum welding power source with a true torque push-pull design, electronic wire spool brake, Trigger Schedule Select and synergic capabilities in both MIG and Pulsed MIG weld settings. 

Reducing Heat Input the Smart Way for Joining Thin Sheets

With its defined heat input, microMIG from SKS Welding Systems reduces distortion significantly: with MAG processes, it is higher by 35 percent to 50 percent.
microMIG from SKS Welding Systems North America uses a pulsed wire feeding technology. Compared to other methods with pulsed wire feeding, microMIG is characterized by a significant difference: instead of using higher frequencies of the wire pulse, microMIG achieves higher deposition rates at lower frequencies. 

Multi-Process Welder Helps Beginners Weld Like a Pro

Push button controls, LED displays and a Quick Start Guide enables first time welders to set up the unit and start welding in a very short time.
Victor Technologies launched the Tweco® Fabricator® 141i 3-in-1 welder, a multi-process welder that runs off 115V household power.
