Lincoln Invertec 160T TIG Welder – 5-160A Amp Range, P/N K1845-1

Tackle sanitary stainless tube fabrication with the portable Lincoln Invertec 160T TIG welder (P/N K1845-1) to produce X-ray clean root passes without tungsten contamination. Food processing plants and pharmaceutical piping facilities reject welds with tungsten inclusions caused by rough scratch starting. This compact 160-amp DC TIG and Stick inverter incorporates high-frequency arc starting, adjustable pulse TIG parameters, and dual-voltage input circuitry to deliver precise puddle control on high-purity piping.

High-frequency arc starting ignites the welding arc without contact between the tungsten electrode and the tube wall, keeping roots free of foreign metal particles. Pulse TIG frequency adjusts up to 200 Hz, constricting the plasma arc to pinpoint penetration while cooling the puddle to prevent tube wall sagging. The compact briefcase chassis weighs under twenty-four pounds, allowing pipefitters to carry the power source up ladders and into tight process skids with ease.

Core Mechanical Specifications of Lincoln Invertec 160T

- 5-160A Precision DC Output Range: Produces clean low-amp arc starts down to 5 amps for thin stainless sanitary tubing.
- High-Frequency Arc Initiation: Strikes an instant DC TIG arc without touching base metal to preserve tungsten geometry.
- Pulse TIG Controls up to 200 Hz: Regulates heat input to prevent burn-through on thin stainless exhaust and food-grade piping.
- Dual-Voltage 120V/230V Input Sensing: Plugs into standard 120V maintenance circuits or 230V fabrication drops automatically.
- Integrated Digital Amperage Display: Shows exact real-time welding current for strict procedure compliance.
- Built-In Gas Solenoid Valve: Controls shielding gas pre-flow and post-flow automatically to prevent crater cracking.
- Ultra-Portable 23-Pound Briefcase Housing: Compact metal cabinet with shoulder strap allows easy one-man climbing on pipe racks.

Commercial Advantages & Heavy-Duty Build

Built for mechanical pipefitters and stainless fabricators, this portable DC TIG inverter delivers laboratory-grade arc stability on remote installations.

- High-frequency arc ignition guarantees clean, inclusion-free weld roots on critical high-pressure sanitary tubing.
- Pulse TIG functionality controls heat-affected zones, preserving stainless corrosion resistance and minimizing post-weld pickling.
