The ArcMaster 400 MSTP is a full multi process, multi voltage, digital control, DC, CC/CV, Pulse MIG/MIG/Stick/Lift TIG inverter power supply.
 Standard features include: Pulse MIG with 8 factory installed pulse programs, digital inductance control, lift TIG start, job Save & Load, VRD and cellulose E6010 compatibility.  This is the ultimate unit designed for Pulse MIG, MIG, DC TIG and Stick welding.
Overview:
Exceptional Performance! Embedded microprocessor with digital controls, delivering perfectly smooth, stable arc characteristics for E6010 Cellulose and low hydrogen electrodes.
Smart Logic and Easy Link! Prevents damage to the internal components if installed to improper voltage. Multi voltage 208-230/460 1 or 3 phase providing maximum flexibility.
Thermal Overload Protection! Indicator alerts the operator if duty cycle is exceeded or airflow is blocked.
Easy to use! Simple, user friendly set-up and operation.
Twist Lock Output Terminals! Allows for easy polarity changing and cable connection.
Remote Receptacle Fitted! Allows remote devices to be connected for controlling amperage and output contactor.
Smart Warning Diagnostics! Alerts operator to power supply abnormalities.
Standards Compliant Integrated VRD! Voltage Reduction Device reduces the OCV when the power supply is not in use. This all but eliminates the risk of electric shock to the operator from the secondary welding circuit.
Job Save & Load! Allows operator to store up to 5 exact optimized welding parameters then digitally recall them with perfect repeatability.
Lift Start TIG! Provides TIG arc starting without use of high frequency.
Hot Start! Adjustable Hot Start for optimized starting performance.
Pulsed MIG Capabilities! With 8 factory installed pulse MIG programs the operator can easily match the appropriate size and type of wire for the welding application. Reduces spatter and distortion, allows better out-of-position puddle control.
Rack Systems! Available in 4, 6 or 8 pack packages with electrical.
