NEW! Blue Lightning™ - High Frequency Arc Starter for non-contact arc initiation. More consistent arc starts compared to traditional HF arc starters. Greater reliability and no maintenance on solid state components. Preset parameters for tungsten sizes from .020 - 3/16 inch provide optimized starting for applications from thick to micro thin material. For unique applications, custom settings are programmable.

DC TIG Features

Exceptionally smooth and precise arc for welding exotic materials.

High-Speed DC Pulse reduces heat input and increases travel speeds.

Stick Features

Tailored arc control (DIG) allows the arc characteristics to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010.

Hot Start™ adaptive control provides positive arc starts without sticking.

Low OCV Stick is a simple design that reduces open-circuit voltage to 5-10 VDC when power source is not in use. This built-in circuit design eliminates the need for add-on voltage reducers.
