WHAT IS CHOPPER TECHNOLOGY®?

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

•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.

WHAT IS VRD™?

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
		voltage (less than
		32 volts) operation.	VRD™ portion of nameplate

•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.

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.

•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.
