Miller® Syncrowave® 400 TIG Welder 907783
The Miller® Syncrowave® 400 is a 400 amp AC/DC TIG welder that is capable of AC and DC pulsed TIG welding. Its inverter design makes this welder much lighter and more energy efficient than its predecessor; the Syncrowave 350 LX.
Miller's Auto-Link® automatic input voltage sensing allows the Syncrowave 400 DX to be hooked up to 208 volt to 480 volt, single phase or three phase, input power without manual linking. The advanced AC squarewave allows for adjustable maximum cleaning or maximum penetration while AC welding on aluminum.

Energy efficient. Save up to
33 percent on energy costs versus
outdated welding equipment.
Pro-Set™ eliminates the guesswork
when setting weld parameters.
Use Pro-Set when you want the
speed, convenience and confidence
of preset controls. Simply select
the feature and adjust until
Pro-Set appears on the display.
Fan-On-Demand™ cooling system only operates when needed.
Auto-Link® circuit automatically links
the power source to primary voltage
being applied (208/240/480 V,
single- or three-phase).
Lift-Arc™ start provides TIG arc starting without the use of high frequency.
Wind Tunnel Technology™ is an internal air flow that protects electrical components and PC boards from dirt, dust, and debris, greatly improving reliability.
LVC™ Line Voltage Compensation
Keeps output of the power source constant regardless of fluctuation in input power +/- 10%.
Squarewave technology is the AC output of a power source that has the ability to rapidly switch between the positive and negative half cycles of alternating current.
Thermal Overload Protection -
Internal components are protected from damage by thermal overload protection which automatically shuts down the unit if duty cycle is exceeded or air flow and cooling are restricted.
Wireless remote compatible - fully compatible with Miller
wireless remote control solutions -
so you can work the way you want
AC TIG Features
Blue Lightning™ - High Frequency Arc Starter for non-contact arc initiation. More consistent arc starts compared to traditional HF arc starters. Greater reliability and no maintenance on solid state components.
AC Balance (60-80%) controls the amount of oxide cleaning (amperage time in EN) which is essential for high quality welds on aluminum.
DC TIG Features
Lift-Arc™ provides arc initiation without
the use of high frequency.
Pulsed DC TIG - pulsing can increase
puddle agitation, arc stability
and travel speeds while
reducing heat input and
DIG control allows the arc characteristics to be changed for specific
applications and electrodes. Lower
the DIG setting for smooth running
electrodes like E7018 and increase
the DIG setting for stiffer, more
penetrating electrodes like E6010.
Hot Start™ adaptive control provides
positive arc starts without sticking.
