MG-300A Digital Weld Monitor for Resistance Spot Welding (formerly known as MG3)
The MG-300A Digital Weld Monitor for Resistance Spot Weldingis available in three versions: Digital Basic, Digital-W1 and Digital-W2. MG3 Digital Basic monitors weld current and voltage and calculates its derived parameters w/dual channel capabilities. While the Digital-W1 version can be equipped with one the Digital-W2 version can be equipped with two displacement measuring sensors. Both Digital-W versions control parts, speed, force and displacement if applicable. The MG-300A Digital Weld Monitor for Resistance Spot Welding is a proven and state of the art solution which meets the needs of many industry markets.
