Miller® Syncrowave® 300 TIG Welder 907782
The Miller® Syncrowave® 300 is a 300 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 250 DX.
Miller's Auto-Link® automatic input voltage sensing allows the Syncrowave 300 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. Processes

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 Save up to 33 percent on energy costs versus outdated welding equipment.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 distortion.
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.

FREE Optrel® Crystal 2.0 auto-darkening welding helmet
Get a FREE Optrel™ Crystal 2.0 auto-darkening welding helmet with the purchase of this Syncrowave® 300 TIG welder. While supplies last. (No substitutions allowed.)Optrel® Crystal 2.0 Welding Helmet 1006.900Features
Crystal lens technology with shade 2.0 light state - See clearly what happens before, during and after the welding process.
AUTOPILOT - Detection of the arc brightness and fully automated shade level adjustment from 4 to 12. Adjusts automatically to the changing light conditions of the current welding process.
Twilight Feature - gradually lightens lens when switching from dark (welding) to light state to ease eye fatigue.
Sensitivity Adjustment - allows operator to change lens switching sensitivity for varying ambient light conditions or outdoor welding in sunlight.
Grind Mode - Switch quickly and easily between weld mode and shade 2.0 grind mode using external controls. There is no need to remove the welding helmet to grind.
TRUE COLOR - The color perception in light state is almost like looking through clear window glass and in dark mode, you enjoy a detailed and high-contrast view of the welding pool with never-seen-before clarity. TRUE COLOR passes more colors of the spectrum through compared to standard "green" spectrum welding lenses.
External Lens Controls include infinite shade 4 to 12 adjustment, delay and infinite sensitivity adjustment and allow for quick switching between weld and grind modes without removing the welding hood.
Heat reflecting paint - helps welder stay cooler under the hood.
Patented Sensor Slide allows the detection angle to be reduced from 120 to 60 to prevent the ADF from responding to welding nearby.
Patented Excenter perfectly centers the welding helmet when in open position for better comfort, balance and less neck fatigue.
Comfort Headband quickly and easily adjusts for size, forward position and top position.
Optrel 2+1 3 year lens warranty (requires product registration)
Hard Hat Adaptable using Optrel's hard hat adapter.
