The Lincoln Electric FlexCut 105 is the high-output end of Lincoln Electric's new FlexCut handheld plasma lineup — delivering 105 amps of cutting power to cut mild steel, stainless steel, and aluminum up to 1-1/2 in. thick in both handheld and mechanized configurations. As outlined on Lincoln Electric's FlexCut product page, the FlexCut 105 fills the gap between the FlexCut 85 and the industrial FlexCut 125 power source — it accepts 400–600V, 3-phase input and is designed for heavy-production fabrication shops that need sustained high-output plasma cutting without stepping to the dedicated mechanized-only FlexCut 125 platform.
The FlexCut 105 carries all the core FlexCut platform innovations: the FlexConnect torch system for rapid torch head and cable swaps, automatic CNC table detection via the built-in CPC port, the Parts-in-Place consumable protection system, integrated air dryer, large LCD display with real-time status monitoring, and 100% duty cycle at rated output. The full eight-process capability (drag cut, fine cut, extended cut, precision cut, gouge, mark, grid cut, and mechanized) matches the FlexCut 85, providing every plasma process a professional shop requires in a single power source.
At 105 A, the FlexCut 105 covers production cutting of 1-in. structural plate at speed and handles 1-1/2 in. maximum capacity for the heaviest structural and industrial applications within the conventional air plasma range. For fabrication shops that regularly cut 3/4 in. to 1 in. plate and want more throughput than the FlexCut 85 delivers, or that need a handheld-capable high-amp machine alongside their CNC table, the FlexCut 105 is the logical top of the handheld FlexCut range.
With a 5-year factory warranty, the FlexCut 105 is backed by Lincoln Electric's full commitment to the new FlexCut platform — the most comprehensive warranty coverage available on a Lincoln Electric plasma cutting system.

At 105 amps, 100% duty cycle, and 1-1/2 in. cut capacity, the FlexCut 105 handles the heaviest production cutting tasks in the conventional air plasma range:
- HVAC ductwork — heavy commercial and industrial HVAC structural work. Heavy structural support steel, industrial equipment mounting frames, and large commercial HVAC enclosures in 1/2 in. through 1-1/4 in. plate cut at production speed. The FlexCut 105 is the right tool for commercial and industrial HVAC contractors cutting heavy structural steel that is common on rooftop equipment installations and industrial plant HVAC systems.
- Automotive — heavy chassis, armor, and specialty vehicle fabrication. Military-spec and specialty vehicle builders working with 1/2 in. through 1 in. armor plate and heavy structural chassis components rely on plasma systems in the 85–125 A range. The FlexCut 105 handles sustained production cutting of these materials in both handheld and CNC-table configurations, with precision cutting mode for tight-tolerance chassis component cuts.
- Structural steel fabrication and heavy plate work. Wide-flange beams, heavy plate, structural tube, and pipe steel up to 1-1/4 in. recommended thickness for structural fabricators, steel erectors, and heavy equipment manufacturers. The 105 A output provides noticeably faster cut speeds on 3/4 in. and 1-in. plate versus the FlexCut 85, reducing production cycle times on high-volume structural cutting programs.
- Art, architectural, and custom fabrication — large scale. Large-format architectural metalwork, structural art installations, and custom heavy steel fabrication projects benefit from the FlexCut 105's combination of 105 A cutting power, plasma marking capability, and CNC table integration. Projects requiring both hand cutting and CNC table cutting are served by the FlexCut 105's dual handheld / mechanized capability from one machine.
- Demolition, industrial MRO, and scrap processing — heavy work. The 1-1/2 in. maximum cut capacity and 100% duty cycle support sustained industrial demolition, decommissioning, and scrap processing of heavy structural steel. Gouging mode handles heavy weld removal and joint face preparation on thick structural sections. For facilities switching from oxy-fuel cutting to plasma on thicker materials, the FlexCut 105 covers the overlap range where both processes are practical.
The FlexCut 105 cuts mild steel up to 1-1/2 in. (38 mm) maximum, with 1-1/4 in. (32 mm) as the recommended production cutting capacity. Per Lincoln Electric's FlexCut product page, the FlexCut 105 is the largest model in the FlexCut handheld lineup. It also cuts stainless steel and aluminum at comparable thicknesses. For pierce-start mechanized CNC applications, maximum pierce capacity may be slightly less than the maximum edge-start capacity — check with Lincoln Electric for material-specific CNC pierce recommendations at 105 A.
The FlexCut 105 is rated at 100% duty cycle at rated output — consistent with all models in the FlexCut lineup. Continuous 105 A plasma cutting without thermal shutdown enables sustained production cutting programs on CNC tables and in-shop handheld applications. For shops running the FlexCut 105 all day on CNC tables, the 100% duty cycle eliminates cooling interruptions that would otherwise reduce throughput.
The FlexCut 105 uses the same non-high-frequency touch start with rapid arc restrike as all FlexCut models. This system re-establishes the plasma arc immediately after crossing gaps, providing the practical performance of a pilot arc system for cutting expanded metal, perforated plate, and irregular surfaces, while avoiding the RF interference that traditional HF arc start systems produce in CNC machine environments. Parts-in-Place consumable detection prevents inadvertent arc initiation with improperly assembled torch consumables.
Yes. The FlexCut 105 includes a built-in CPC port with automatic CNC table detection — the same CNC interface provided on the FlexCut 45, 65, and 85. The mechanized Ready-Pak (K5827-M) ships with a FlexConnect PRO mechanized torch configured for CNC table mounting. For shops with existing CNC table infrastructure, the FlexCut 105 connects and configures automatically on table power-up. For new CNC table installations, Lincoln Electric's Torchmate tables support the FlexCut 105 as a high-output plasma power source option.
The FlexCut 105 requires 80–120 PSI compressed air with air flow demand appropriate for 105 A cutting — approximately 12–16 SCFM at cutting pressure for sustained production operation. A rotary screw compressor producing 15+ SCFM at 125 PSI is recommended for continuous CNC table or production handheld operation. A large-tank (80-gallon) reciprocating compressor can sustain the FlexCut 105 in intermittent to moderate cutting applications. Industrial air treatment (coalescing filter + moisture separator) is required before the plasma inlet to protect consumable life at 105 A cutting levels where moisture and oil contamination accelerate electrode wear significantly.
