Maxstar 400

907716 / 907716002 / 907716001

The Maxstar 400 is a powerful, compact power source capable of welding higher thickness. This machine delivers an exceptionally smooth and precise arc for welding exotic materials. Blue Lightning™ – High-Frequency Arc Starter for more consistent non-contact starts and greater reliability compared to traditional HF arc starters High-speed pulse controls add arc stability, reduce heat input and warpage, and can increase travel speeds in welding. This inverter-based machine delivers maximum productivity and weld quality while conserving energy compared to traditional welding machines. Tailored arc control (DIG) allows the arc characteristics to be changed for specific applications and electrodes.

Intuitive Interface LCD Display – Ensure proper machine setup and parameter selection with informative on-screen explanations and dynamic images.
Locks and Limits – Provide control of the weld parameter ranges, minimizing deviations from the welding procedure specifications (WPS).
QuietPulse – QuietPulse is activated by changing the waveshape for DC pulse welding, creating a slower, more fluid transition between the background and peak amperage to create the least possible audible noise.
Blue Lightning – High-frequency (HF) arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability compared to traditional HF arc starters.
Stick Features – Tailored arc control (DIG) lets you adjust arc characteristics for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010. Hot Start™ adaptive control provides positive arc starts without sticking.
USB Port – Lets you easily update software, back up settings, and transfer saved weld programs from one unit to the next.
Program Memory – Allows easy naming, saving, and recalling up to 99 custom weld programs.
Pro-Set Features -This feature eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of pre-set controls. Simply select the feature and adjust until Pro-Set appears on the display. The Pro-Set feature is available for Balance, Frequency, Pulse, and DIG parameters.
Auto-Line Technology – Allows hookup to either single-phase or three-phase primary input voltage, 208-600 volts dependent on the machine, with no manual linking, providing convenience in any job setting. An ideal solution for dirty or unreliable input power.
DC TIG Features– Exceptionally smooth and precise arc for welding exotic materials. High-speed DC TIG pulse controls – Pulse frequency capable of pulsing 5000 pulses per second. Pulsing adds arc stability, reduces heat input and warpage and can increase travel speeds. Other parameters include peak amperage, peak time, and background amperage.
Cooler Power Supply (CPS) – An integrated dedicated-use receptacle to power the Coolmate™ PRO 4.
