Welding Equipment MMA Series--Dual Voltage 220V/380V
Product Description
MMA Series--Dual voltage 220V/380V
MMA250/MMA315/MMA400
Technical Advantages
• One-key selection mode of welding stick.
• Automatic voltage recognition, automatic conversion.
• Power saving design, no arc in 5 seconds interval, automatically cut off the main circuit power supply, safe and reliable.
• VRD low voltage technology, safe.
• 3 seconds short circuit protection: the welding rod and the work piece will not be in contact for 3 Seconds without arcing, and the main circuit power supply will be automatically cut off.
• Welding current current adjustment is accurate to 1A.
• Arc starting current continuously adjustable, which significantly improves arc starting performance.
• Thrust current 100m output cable is normally welded.
