Lincoln Square Wave TIG 200 Welder – 10-200A Amp Range, P/N K5126-1

Description

Motorsport chassis fabricators relying on the Lincoln Square Wave TIG 200 welder (P/N K5126-1) eliminate thermal distortion on thin aluminum tubing through adjustable high-frequency pulse settings. Hobbyist and custom automotive welders struggle with arc wander and puddle contamination when operating basic TIG units without square-wave alternating current. This dual-voltage inverter machine features square-wave AC technology, an intuitive control interface, and an adjustable pulse frequency up to 20 Hz that narrows the heat-affected zone.

High-frequency arc starting ignites the welding arc without tungsten touch contact, preventing weld contamination on critical roll cages and marine fuel tanks. Adjustable AC balance control lets you dial in the cleaning ratio to strip heavy oxide layers from aluminum while maintaining deep root penetration. Dual-voltage input circuitry accepts 120V or 230V primary power, allowing you to move between garage outlets and shop fabrication benches with ease.

Core Mechanical Specifications of Lincoln Square Wave TIG 200

• 10-200A AC/DC TIG & Stick Window: Fuses thin 24-gauge aluminum body sheet up to 3/16-inch structural plate.
• High-Frequency AC/DC Arc Ignition: Lights the arc without touching tungsten to plate, preventing tungsten inclusions.
• Adjustable AC Balance Control: Sets oxide cleaning and penetration ratios precisely on oxidized aluminum castings.
• Integrated Pulse TIG up to 20 Hz: Regulates heat input to prevent burn-through on thin automotive body panels and tubing.
• Dual-Voltage 120V/230V Primary Input: Operates at 125 amps on 120V household lines and 200 amps on 230V shop current.
• Standard 14-Pin Foot Remote Included: Delivers stepless current adjustment to control puddle freeze and prevent crater cracking.
• Lightweight 46-Pound Inverter Housing: Compact metal cabinet with dual carry handles permits easy one-man shop transport.

Production Efficiency & Reduced Post-Weld Cleanup

This compact AC/DC TIG machine gives custom fabrication shops laboratory arc stability with simple parameter setup.

• Square-wave AC technology produces a stiff, directed arc cone that penetrates deep root joints without wide heat spreading.
• Foot pedal remote control lets you adjust heat dynamically while welding out-of-position roll cage joints and exhaust collectors.

Material Capacities & Workshop Integration

Weighing 46 pounds dry with an exterior length of 19.8 inches, this dual-voltage unit welds 3/16-inch aluminum plate on 230V power and runs clean on 7,000-watt generators.

Factory Warranty Terms & Consumable Care

• Lincoln Electric backs the Square Wave TIG 200 power source with a 3-Year factory warranty covering internal inverters and electronics.

Maintain dedicated grinding wheels for tungsten sharpening, blow shop dust out of the cabinet cooling louvers every 50 hours, and check argon gas hose fittings for leaks.
