The POWER MIG® 350 has the electronics build-in for all three methods - no PC board add-ons are required. Two Year Extended Warranty Available in the U.S.A. and Canada KEY CONTROLS Easy to use controls for high productivity and accurate settings. A. Continuous WFS/Amps Control – In wire feed welding, adjusts wire feed speed. In stick or TIG modes, adjusts amperage. B. Continuous Volts/Trim Control – Adjusts voltage when MIG welding. Adjusts the arc length (trim) when Pulse-MIG welding. A B The Professional’s ChoiceSM – weld with traditional manual control or take advantage of the included MSP3 digital panel for high tech weld features: 1. Weld Mode – Many synergic modes to select from for simple one-knob control. 2. Preflow – Adjustable timer to initiate gas flow before the arc. 3. Post-Flow – Further protect your weld integrity by automatically setting the gas to run a few seconds after the trigger is released. 1-9 1 4. Run-In – Adjustable speed at which wire strikes the plate to enhance starting. 5. Start Procedure – Set start procedure, wire feed speed and volts for an adjustable starting time. 6. Arc Control – Set arc control to crisp or soft depending on your preference and application. In pulsed MIG, this control varies the pulse frequency and background current. In Stick mode, it adjusts the arc force. 7. Crater Control – Adjusts the ending weld procedure and ramp down time. 8. Burnback – Adjustable time delay between turning off the arc and the wire feed to prevent wire sticking to the puddle. 9. Spot Timer – Adjustable arc time for repetitive tack and spot welds. ARC PERFORMANCE Lincoln Innovations for Challenging Applications Waveform Control Technology® makes it possible to take advantage of Lincoln Electric innovations like these patented processes: Pulse-On-Pulse® uses a sequence of varying pulse wave shapes to produce a TIG-like bead appearance and excellent weld properties when MIG welding aluminum. Pulse-On-Pulse® controls arc length and heat input together, making it easier to achieve good penetration. See NX-2.10 Pulsed MIG PULSE FREQUENCY WELDING CURRENT Pulse-on-Pulse® Peak Ramp Up Tail Out Background Step Off TIME Pulse-On-Pulse® on 3 mm Aluminum Power Mode® Power Mode® reduces spatter and improves bead appearance, even for low voltage procedures on stainless. Low Heat (Background) Power Mode® aids bead wetting and penetration on aluminum. Power Mode® uses high-speed regulation of output power to deliver extremely fast response to changes in the arc, for example, when using a whip technique. The result is improved MIG welding performance, including low spatter, very uniform, consistent bead wetting and controlled penetration. Power Mode® benefits are especially apparent on low voltage applications on thin steel and stainless steel material less than 20 gauge (0.7 mm). See NX-2.60 High Heat (Peak) Pulsed MIG varies weld current between peak (high heat) and background (low heat) current to provide better control of heat input, which minimizes warping and burnthrough on thin materials. Pulsed MIG also enables flat, horizontal, vertical up, or overhead welding without a slag system. Optimized GMAW-P waveforms are readily available to use on aluminum, carbon steel, high strength low alloy steel, stainless steel, and nickel alloys. See NX-2.70 Synergic MIG 2. Voltage is automatically set. 1. Use one knob to set procedures. Synergic MIG Synergic control of voltage and wire feed speed allows you to set weld procedures with only one control for simplicity and ease of use.
