POWER MIG?? 255XT
POWER MIG??. The Professional???s ChoiceSM.
The POWER MIG?? 255XT sets the standard for MIG and flux-cored welding in light industrial job shop fabrication, maintenance or repair work. Diamond Core Technology??? delivers a wide voltage sweet spot across the welding range, low spatter levels and a forgiving arc on steel, stainless and aluminum ??? even for demanding out-of-position work.
It???s Spool Gun Ready, so it???s fast and easy to tackle difficult aluminum applications. Exclusive 115 volt auxiliary power means you can power lights, grinders, and chargers right where you work! And, the MAXTRAC?? drive system with a patented Split Wire Guide system and tachometer feedback ensures trouble-free wire delivery. Add the extra length 15 foot gun cable and innovative convenience features and you begin to understand why the POWER MIG?? 255XT is considered The Professional???s ChoiceSM.

PERFORMANCE
What Is It?
Diamond Core Technology??? is a patented innovative choke design that filters the welding arc. It provides dynamic optimized arc filtering across the entire welding range of amperages. Other arc stabilization methods are ???fixed??? ??? or only working at certain amperages ??? resulting in harsh arc characteristic changes over the welding range.
(1)Lincoln Electric recommends multiple pass welds on 1/2" (12.7 mm) material. Consult the appropriate application procedures and guidelines for selecting the correct wire size, gas type and number of passes.
(2).035" and .045" (0.9 and 1.1 mm) NR??-211-MP is only recommended up to 5/16" (7.9 mm) thick material.

QUALITY AND RELIABILITY
???Fan-As-Needed??? (F.A.N.???) provides cooling of transformer and other components when welding, reducing power consumption, noise and extending welder life.
???Thermostatic protection from current overload and excessive temperatures.
???Printed circuit boards are environmentally-shielded using Lincoln's engineered potting and protective frame trays.
???Low input current draw for energy-efficient low cost operation.
???Power source line voltage regulation holds voltage setting constant to maintain weld quality even when the input voltage fluctuates ??10%.
???Manufactured under a quality system certified to ISO 9001 requirements and ISO 14001 Environmental Standards.
???Approved by Canadian Standards Association (CSA).
???Three-year warranty on parts and labor (90 days warranty on gun).
SPOOL GUN READY!
The POWER MIG?? 255XT has built-in electronics to drive either a Magnum?? SG Spool Gun or a Magnum?? 250LX Spool Gun. In addition, a second gas solenoid is provided to supply and control
gas flow to the spool gun.
Easy as 1-2-3!
1Simply plug the spool gun control cable into the built-in 7-pin connector (Magnum?? SG gun requires K2445-1, 6- to 7-pin
control cable adapter plug.)
3Hook the spool gun gas line to the solenoid gas fitting and you???re ready to weld!

POWER MIG?? 255XT SPOOL GUN SOLUTIONS
The economic Magnum?? SG or premium Magnum?? 250LX spool guns are recommended for easy changeovers to a second electrode mate- rial such as stainless steel or aluminum.
Avoid the time-consuming liner, contact tip, drive roll and machine polarity changes necessary when preparing your machine???s wire drive
for use with those materials. Spool guns are especially recommended for feeding soft aluminum wire.
Lincoln???s spool guns accommodate 4" (100 mm) diameter 1 lb. (.45 kg) spools and feature convenient wire feed speed control at the gun handle.
MAGNUM?? SG SPOOL GUN
???250A, 60% duty cycle.
???.025" - 3/64" (0.6-1.2 mm) electrode diameter capability.
