Changed figures: Refers to Figure B.2a and B.3a

Changed text in right column:The welder is shipped from the factory ready to feed 12" (305mm.) diameter spools with 4" (102 mm.) maximum width. These spools fit on a 2" (51 mm.) diameter spindle that has a built in friction brake to prevent overrun of the spool and excess slack in the wire. Adjust the brake tension with the thumbscrew on the spindle hub, until the reel turns freely but with little or no overrun when wire feeding is stopped. Do not overtighten.

Be sure that this stud engages the hole in the wire spool.

Figure B.2a

To use 8" (200 mm.) diameter spools the S18221 Spindle Adapter must be mounted on the spindle in between the 8" spool and the retaining collar. See Figure B.3a.

SP 170-I, SP-170T specifications

Lincoln Electric has long been synonymous with quality welding equipment, and the SP-170T and SP-170-I models are no exception. These compact and powerful machines are designed primarily for hobbyists, DIY enthusiasts, and small-scale welding operations. Both models showcase Lincoln Electric’s commitment to delivering innovative technology and user-friendly features.

The Lincoln Electric SP-170T is a transformer-based MIG welding machine, ideal for both steel and aluminum projects. One of its main features is its lightweight, portable design, which allows users to transport it easily to job sites or workshops. It has a 30 to 140 Amp output range, enabling it to weld materials from 24-gauge to 3/16-inch thick. Its built-in gas solenoid valve and drive motor provide efficient and consistent feeding of welding wire. Moreover, the unit features an adjustable wire feed speed that gives users greater control over their welds.

The SP-170-I, on the other hand, is a more sophisticated inverter-based MIG welder. This machine uses advanced inverter technology that allows for a more compact design while maintaining the ability to deliver high-quality welds. The SP-170-I operates on 220V single-phase input power, providing a robust output for a wide range of welding applications. Its adjustable output settings allow users to customize their welding experience to fit specific needs. The machine is equipped with a unique Digital Control System that enhances the arc performance and allows for greater precision.

Both models come with Lincoln Electric’s renowned drive system, which is designed to provide smooth feeding of welding wire, minimizing the risk of jams and inconsistencies during the welding process. Additionally, both units are equipped with thermal overload protection, which safeguards the machines from overheating and prolongs their lifespan.

In summary, the Lincoln Electric SP-170T and SP-170-I are versatile, powerful, and user-friendly MIG welding machines suited for a variety of applications. Their lightweight and portable designs, coupled with advanced features and technologies, make them perfect choices for hobbyists and professional welders alike. Whether for home projects or small fabrication work, these machines deliver exceptional performance and reliability, making Lincoln Electric a trusted name in the welding industry.
