Exclusive! MIG/Synergic MIG, AC/DC Pulse TIG, and Stick design.
High Frequency and Lift Start AC and DC TIG modes for a true "all in one" design
Digitally controlled operation in all modes improve control and dependability.
Operator friendly panel without complicated hidden menus or adjustments with grouped controls.
Synergic function MIG automatically adjusts wire speed while voltage is increased or decreased. This maintains a preset ratio of volts and amps that can be tweaked manually by user for best operation.
Manual Override of Synergic MIG function allows the user to regain control of at any point to fine tune automatic voltage settings and allows operation in full manual mode if desired.
Weld Aluminum, Stainless, or Steel with Synergic MIG function with wire diameter from .023- .045" (for full range of sizes and flux core use, purchase optional drive rolls).
9 channel memory function provides easy saving and recall of your favorite settings.
Synergic Spool gun operation capability with optional spool gun. Ideal for welding aluminum.
TIG torch and Foot pedal included for TIG. Regulator included.
Built in gas solenoid and connections for TIG eliminates need for gas valve torch used by competitors
True DC CC/CV Multi-Process design eliminates needing or carrying multiple units for one job.
AC capability on TIG allows user to weld aluminum. Industry first for this type design.
Pulse TIG capability increases control and weld quality.
Compact and light weight design makes the unit extremely portable, ideal for on-site fabrication.
Adjustable Burn-back control keeps the wire energized after wire has stopped feeding to allow the wire to melt back to a desired length without retrimming wire before restarts.
8" Diameter wire spool capacity maintains portability while maintaining productivity.
Adjustable MIG Wave arc force control manages slope/ inductance and fine tunes arc characteristics.
Adjustable stick Arc Force and New Hot Start controls allows the user to dial in desired Stick welding performance.
TIG Up and Down slope allows the user to control the end of the welding cycle.
2T/4T torch trigger/latch function offers stepped control welding with TIG and MIG.
Adjustable Pre and Post flow for TIG and MIG operation improves over all weld quality.
200 Amps of MIG and TIG power offer more than enough power to get the job done. 160 amps of stick welding power can be used with up to 1/8" welding rods.
Dual Voltage design will operate on 120V or 240V. Output on 120V is limited to 125 amps MIG/TIG/ 100 amps Stick.

NOTE: Use only with a generator rated by its manufacturer as "clean power" if using with a generator. Consult manufacturer of generator for certification. Everlast does not approve or endorse generator brands or models, however, if the damage to the welder occuring from use with a generator not labeled as producing clean power by its manufacturer is not warrantable. Typically clean power is represented as less than 5% THD.
