ZX7-250LCD screen
1. Imported IGBT single tube, wide voltage 120V-540V, high and low voltage welding, fast arc starting, welding at one touch
2. LCD display: one-click conversion adjustment of welding current, arc current and thrust current
3. The diameter of the welding rod can be selected to directly and automatically match the current welding, making it easy for novices to get started quickly.
