PERFORMANCE
Arc Performance
• 400 amps @100% duty cycle with output range up to 500 amps
using Chopper Technology ® . All ratings are at temperatures
of 104°F/40°C.
• Arc Gouging with up to a 5/16" carbon.
• VRD ™ (Voltage Reduction Device ™ ) reduced OCV (open circuit
voltage) in CC-stick welding mode for added safety.
• CC-Stick mode is optimized for general purpose stick using
E7018 low hydrogen electrode.
• Built-in “hot” start for easier starts and restrikes minimizing the
electrode “sticking” to the work.
• Downhill pipe mode with active arc force control - enhanced
downhill pipe welding mode. Excellent for cellulosic electrodes.
Fast travel speeds, especially on fill passes. Arc control adjust-
ment for a soft, buttery arc or a more forceful digging arc.
• Standard Touch-Start DC TIG ® welding, not scratch start, for easy
arc starting that avoids tungsten contamination and the use of
high-frequency equipment.
• Excellent CV wire welding with cored-wire and MIG (CO2 and
blended gas). 3/32" E70T-6 up to 260 IPM, 27V.
Generator Performance
• 3-Phase 240V AC generator power rated at 19 kW peak (17 kW
continuous) output to power industrial equipment such as
a plasma cutter, pump or inverter welder. Simultaneously weld
and use 3-Phase AC power - for example, up to 9,400 watts can
be delivered while welding at 300 amps. Compare to competitive
product which has 3-Phase power available as an extra-cost fac-
tory-only option.
• 3-Phase 240V receptacle on control panel eliminates the need to
hard-wire the connections.
• The Vantage ® 400 provides added value at the job site by deliver-
ing up to 12 kW peak (11 kW continuous) watts of 1-Phase AC
auxiliary power for equipment such as a Lincoln plasma cutter.
Also use for lights, grinders and other common construction
tools. And, you can simultaneously weld and have access to AC
power – 4,700 watts can be delivered while welding at 300 amps.
• AC generator voltage is constant at 120V or 240V at any weld
dial setting.
• Two 120V GFCI duplex receptacles.
• All receptacles are circuit breaker protected and have weather
protective covers.

A CLOSER LOOK
Patented and award-winning Lincoln Chopper Technology ® delivers
superior DC arc welding performance for general purpose stick, Downhill
Pipe, DC TIG, MIG, cored-wire and arc gouging.
Benefits of Chopper Technology ® include:
- Easy arc starting
- Smooth arc action
- Low spatter levels
- Excellent bead appearance
Traditional weld control is more
variable around the desired output.
Chopper Technology ®
delivers extremely fast response
for smoother output control.
WHAT IS CHOPPER TECHNOLOGY ® ?
WHAT IS TOUCH-START TIG ® ?
Touch-Start TIG ® uses a very low voltage to sense when the tip of
the tungsten electrode is touched to the work piece. When this
occurs, a complete circuit is established. When the tungsten is then
raised from the work piece, the circuit senses a change in voltage
and initiates the appropriate welding current and voltage to support
the TIG welding process.
Enjoy the added benefits of Lincoln’s Touch-Start TIG ® when DC TIG
welding. Not only do you avoid tungsten contamination when arc
starting, but you also don’t need extra high frequency equipment.
The VRD ™ (Voltage Reduction Device ™ ) provides additional safety in the
CC-Stick weld mode, especially when working in an environment with a
higher risk of electrical shock such as wet areas and hot, humid sweaty
conditions. The VRD
™ reduces the OCV (open circuit voltage) at the welding
output terminals while not welding to less than 32 volts DC.
The VRD ™ is activated by flipping a toggle switch inside the machine to the
“ON” position. Indicator lights monitor the voltage: green for less than 32
volts while not welding, and either red (greater than 32 volts) or green while
welding, depending on the actual voltage of the arc.
Other weld modes when VRD ™ is on:
Downhill Pipe – There is no output.
CV-Wire – OCV is not reduced.
Touch Start TIG ® – No difference in
operation. TIG is
normally a low
voltage (less than
32 volts) operation.
