Omega PA250i Welding System
The Case for Copper
One of the biggest challenges when welding EV batteries is finding a welder capable of welding highly conductive metals such as copper and aluminum. Inside a lithium-ion battery are various copper and/or aluminum components that carry the electrical current (such as buss bars). These components are commonly joined to either similar or dissimilar materials to facilitate the electric current. If the joint is not made properly, there is a potential for voltage drops due to the resistance between the two pieces. The Omega PA250i welder is capable of overcoming some of these challenges, thus opening new doors in the world of EV battery welding, specifically by being able to weld copper tabs to battery cans.
With copper tabs, power cell efficiency significantly improves. And when the customer experience is all about battery performance, copper is king!

Weld Confidently
With copper, attach a thicker tab for a larger spot size and improved peel strength. Plus, the heat affected zone is small, quick and won’t damage the power cell’s internal components.
Copper to steel, copper to aluminum, nickel to steel—ideal for battery welding!

Overview and Applications
The Omega PA250i Copper Tab Battery Welder is capable of welding highly conductive metals such as copper and aluminum. It also comes in a CNC version that is capable of performing all the same tasks with the assistance of a CNC table.
This system brags an all new design and performance. This latest update takes all of the great features from our previous model and adds to it a new motorized weld head adding greater control, precision, and uniformity to every weld. Manufacturers can produce lighter, more compact battery packs without compromising power or capacity.
Features and Benefits of the Sunstone Omega PA250i Copper Battery Tab Welder:
Solderless Connections– The metals are fused together at the weld spot for a continuous connection and no voltage drops.
Clean Weld Spots– During the welding process, surface contaminants are burned off, allowing for strong, clean welds.
Weld Dissimilar Metals– Sunstone Spot Welders can weld any combination of metals, such as Copper to Aluminum.
Small Heat Affected Zone– The heat-affected zone (HAZ) is very small and very localized to ensure no degradation to the battery. The 250i provides enough energy to make the weld without affecting the integrity of the cell.

By far my most popular chain style for permanent jewelry! Catches the light for the sparkle we all want and the paperclip style is so on trend right now.
I absolutely love the ease and use of this machine. I had no idea what I was doing and left it in the box before I got up the nerve to attempt it. It was so easy. I will hopefully help anyone who gets the idle error. I couldn’t find a troubleshoot for it in the manual but googled it and it’s as simple as not pushing the button until it was orange. Prior to my receiving my Orion I spoke with 3-4 different departments at Sunstone and there customer service is A+. Everyone sounded so happy to assist and help me and I’m so pleased with my purchase. Thank you!
