This multi-process welder delivers up to 815 amps of welding power for a variety of applications, including construction, shipbuilding and heavy fabrication. Embedded CrossLinc Technology drives welding control at the arc without an added cable to save costs, increase quality and enhance productivity and safety on the job site.

The world-ready Flextec 650X will run on a wide range of available voltage input power and is IP23 rated for outdoor operation and storage. Broad wire feeder compatibility is not an issue – The Flextec 650X will operate with almost any Lincoln Electric wire feeder or welding process.

Simple. Reliable. Flexible. Specify the Flextec 650X for your heavy duty applications.

Key Features

Simple

• Easy one-knob weld process selection
• Fast inverter arc response means smooth arc action and consistent bead appearance
• User weld schedule memory storage allows easy recall of your critical or often repeated weld procedures with applicable feeders
• Synergic single knob control over wire feed speed and voltage with applicable feeders

Reliable

• Components designed to run cool for long life in high temperature environments
• Engineered for outdoor use and harsh environments (IP 23 rated)
• Desert Duty Rated for extreme temperatures up to 55°C

Flexible

• Ideal for large diameter wire or stick welding on thick materials
• Compatible with most Lincoln Electric feeders, including including older and new common bench and boom models, portable across-the-arc models and CrossLinc Technology or ArcLink-equipped models
• ArcLink digital communication compatibility ensures the Flextec 650X remains ‘future-proof’ as new wire feeders are introduced
• Premium arc characteristics on all DC wire, stick and TIG processes
• Large output range: 10-815A allows you to weld 20 ga stainless all the way through gouging with 1/2 in. carbons
• 115VAC duplex receptacle to power tools, lights, and accessories

CrossLinc Technology Compatibility

• When this machine is paired with a CrossLinc technology enabled accessory, many benfits are unlocked
• Full functionality without control cables
• Enables remote procedure setting at the feeder to improve weld quality
• Increases arc time with fewer trips to the power source to adjust settings
• Improves safety by reducing jobsite clutter
