[Tweet](https://twitter.com/share) ![Comparison showing welding die-cast with AC pulse welding vs. AC Synchro-feed Evolution welding](https://blog.daihen-usa.com/hs-fs/hubfs/1-Blog/blog-new-technology-resolves-problems-welding-aluminum-and-high-tensile-materials.gif?width=735&name=blog-new-technology-resolves-problems-welding-aluminum-and-high-tensile-materials.gif) In response to the global trend toward carbon neutrality, materials are being shifted to high-tensile materials that are thinner and stronger and aluminum that is lightweight for weight reduction in products. However, there is one common problem when using high-tensile materials or aluminum, it becomes difficult to weld joint shapes because of the variation in the joint gap. To solve this challenge, OTC DAIHEN has evolved its exclusive [robotic welding](https://www.daihen-usa.com/welding-robots/) technology, creating [Synchro Feed Evolution with Push Arc welding mode.](https://www.daihen-usa.com/low-spatter-synchro-feed-evolution/) ## What is Push Arc Mode in Synchro Feed Evolution? Push Arc creates an ultra low-spatter, wide and flat bead that is achieved by improving the wire feed control frequency of the original Synchro Feed technology and adding a new waveform control to improve the welding joint tolerance. The Push Arc shortens the arc length by increasing the short-circuit frequency, the force and the number of times the arc pushes the molten metal to spread the molten metal into a flat and wide bead. ![Conventional vs. Push Arc](https://blog.daihen-usa.com/hs-fs/hubfs/1-Blog/push-arc.png?width=687&name=push-arc.png) Check out the differences in these welding processes using Synchro Feed Evolution Push Arc mode compared to a DC pulse, DC and the older Synchro Feed technology. ![Comparison between welding processes.](https://blog.daihen-usa.com/hs-fs/hubfs/1-Blog/comparison-welding-process.png?width=873&name=comparison-welding-process.png) ## Push Arc Mode Reduces Blow Holes when Welding Zinc Plate Blow holes are often a problem when welding zinc plate. The Synchro Feed Evolution Push Arc mode expands the molten pool, making it easier to release zinc vapor and suppress blow holes. ![Zinc welding Push Arc vs. conventional welding.](https://blog.daihen-usa.com/hs-fs/hubfs/1-Blog/zinc.png?width=743&name=zinc.png) ## Push Arc Mode Reduces Burn-Through when Welding Aluminum Joints are complicated to weld on aluminum due to its lower hardness, various plate thicknesses and makeup of many types of alloys. Burn-through and insufficient melting are common challenges. Push Arc mode resolves these problems with its high heat input control performance. See below for how the welding amount increased by about 20% with AC Push Arc when compared to DC. ![Aluminum welding voltage chart DC Push Arc vs. AC Push Arc.](https://blog.daihen-usa.com/hs-fs/hubfs/1-Blog/aluminum.png?width=855&name=aluminum.png) ## Push Arc Mode Creates Better Looking Die-Cast Aluminum Welds Because die-cast material contains gas (hydrogen), the bead will turn black with a large amount of soot. The NEW Push Arc mode eliminates this soot to create beautiful welds on die-cast aluminum. ![Die-cast welding AC pulse vs AC Synchro-feed Evolution welding.](https://blog.daihen-usa.com/hs-fs/hubfs/1-Blog/die-cast.png?width=852&name=die-cast.png) ## New Weld Technology Includes Easy Maintenance The new Synchro Feed Evolution technology also reduces by 90% the number of cleanings needed for aluminum welding, which ultimately increases productivity. The technology’s air purge function automatically discharges wire shavings. Additional user-friendly features include: - Consolidation of the cables and hoses between pull feeder and coaxial power cable. - A one-action connection that takes about 2 minutes, compared to the previous 30 minutes or more. - Easy and reliable installation even for inexperienced users. ## Synchro Feed Evolution Models OTC DAIHEN’s Synchro Feed Evolution with the new Push Arc mode is available in standard and lite models. **Contact your** [**regional OTC DAIHEN rep for more information**](https://www.daihen-usa.com/meet-the-team/). ![Synchro-feed Evolution models standard vs. lite.](https://blog.daihen-usa.com/hs-fs/hubfs/1-Blog/synchro-feed%20(1).png?width=816&name=synchro-feed%20(1).png)   Topics: [Robotic Welding](https://blog.daihen-usa.com/topic/robotic-welding) ### **Subscribe!** Get **Keeping It Clean**, a monthly enewsletter with all the latest in welding and robotic automation. # New Technology Resolves Problems With Robotic Welding Aluminum and High-Tensile Steel Posted by [OTC DAIHEN](https://blog.daihen-usa.com/author/otc-daihen) on September 29, 2022 - [Tweet](https://twitter.com/share) ![Comparison showing welding die-cast with AC pulse welding vs. AC Synchro-feed Evolution welding](https://blog.daihen-usa.com/hs-fs/hubfs/1-Blog/blog-new-technology-resolves-problems-welding-aluminum-and-high-tensile-materials.gif?width=735&name=blog-new-technology-resolves-problems-welding-aluminum-and-high-tensile-materials.gif) In response to the global trend toward carbon neutrality, materials are being shifted to high-tensile materials that are thinner and stronger and aluminum that is lightweight for weight reduction in products.
