Features - Wind Tunnel Technology™ - Internal air flow that protects electrical components and PC boards from dirt, dust, debris... greatly improving reliability.
- Fan-On-Demand™ - operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine.
- Lift-Arc™ - start provides TIG arc starting without the use of high frequency.
- Adaptive Hot Start™ for Stick - Automatically increases output amperage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion.
- Lightweight, aerospace-grade aluminum case offers protection with the benefit of reduced weight.
- Inverter arc control technology provides greater puddle control for superior 6010 Stick electrode performance.
- LVC™ Line Voltage Compensation keeps welding output constant even if input power varies by +/-10%. Line voltage compensation further expands to +37% and -59% when operating on 460 VAC.
- Process selector switch reduces the number of control setup combinations without reducing any features.
- Large, dual digital meters are easy to view and presettable to ease setting weld output.
- Compatible with the Wireless Remote Hand Control. Improve productivity, eliminate clutter and cord tangles in the work area. Eliminate cord failure and associated downtime/repair costs and extend the operator's welding range without adding cord extensions.
- Auto Remote Sense enables unit to automatically use remote control if connected to remote control receptacle (CC/CV models only).
- Low OCV Stick - A built-in, selectable feature, that reduces the Stick mode open-circuit voltage (OCV) to nearly 15 volts when the welding power source is not in use. Eliminates the need for add-on voltage reducers.
-
Ultra-tough, polycarbonate-blended cover for control panel protects front controls from damage.
- Insight Core Optional Welding Intelligence system compatible - XMT CC/CV models are Insight capable to monitor weld voltage, amperage, and arc-time and percentage while MIG or Flux-cored arc welding.
-
Optional gas solenoid for TIG welding.
