Robotics + Electronics

Hello all. I posted this here because the question doesn't really fit anywhere. I have already completed several battery projects. Until now I have always soldered the connections carefully. But now I have to make several large packs, and the soldering method is honestly too tricky for me. Does anyone have a recommendation for a spot welder? It should not have too high starting currents (like the Sunkko devices), and if possible be operable with one hand or with a foot pedal. After my research, I unfortunately found that many of the cheaper devices have massive problems with durability or operation. Thanks in advance
