The DA-3 features an LCD screen that displays all welding settings. You can easily adjust these settings using the control knob. The welder is designed for ease of use, with a synergic mode that simplifies the welding process. Simply select the type and size of the key or stud, as well as the metal thickness, and start welding. If you need to make more precise adjustments, you can switch to manual mode by pressing the control knob for 3 seconds. This allows you to fine-tune the weld power and time as needed.

In manual mode, you can save and name your welding settings for future use (maximum 13 characters). The welder has a memory capacity of up to 64 programs, making it easy to recall your preferred settings.
