Features

• Full-featured 255 A TIG welder with a water-cooled torch for longer weld times, cooler operation and enhanced dexterity
• Ideal for production welding environments
• Amperage Control: Allows for adjustments from fine control for thinner materials up to maximum setting for thicker materials
• Arc stability offers increased low amperage performance
• TIG 2 or 4 stage Continuous Modes: Selectable continuous amperage output with both 2-stage setting for use with optional controls and 4-stage automatic modes
• TIG 2 or 4 stage Pulse Modes: Selectable pulsed amperage output with both 2-stage setting for use with optional controls and 4-stage automatic modes
• Duty Cycle: Higher duty cycles for longer weld times and current stability
• AC Balance Adjustment: Provides the ability to select from three separate functions
• Penetration: Provides a narrow bead with maximum penetration, ability to adjust eight individual selections to tailor the setting
• Balanced: Ideal ratio between width and depth of welding bead
• Cleaning provides a wider bead and maximum material oxidation, ability to adjust eight individual selections to tailor the setting
• Pulse Adjustment Controls the max amperage on-time to determine the amount of heat transfer into the material
• Additionally, this feature defines the weld puddle size and allows an added level of timed puddle formation when using a filler rod
• Background Amperage Adjustment: Amperage ranges from 10-150 Amps AC and 5-150 Amps DC for controlled low pulse heating and minimal distortion of the parent metal when required
• AC Frequency Adjustment: Variable 50-150 Hz adjustment between maximum arc focus, narrower heat cone displacement and broader arc focus, wider heat cone displacement
• Upslope/Down-slope Adjustment: Provides a soft-start and finish to current ramp-up/ramp-down, adjustable from 0-10 seconds
• Ideal for minimizing burn through at material edges
• Post gas Flow Adjustment: Maintains gas flow from 0-30 seconds after welding is complete to ensure a clean weld appearance and minimal contamination
• High Frequency/Scratch Starting
• Choose between HF mode for controlled arc starting or normal scratch start mode when HF is not desirable
• Power Factor Correction: Minimizes power requirements due to efficient system design, requiring lower input power supply currents
• Allows for input voltage tolerances of +15% to -20% and saves substantial electricity cost
• Weld Parameter Recall is capable of saving nine individual weld setting parameters for quick recall
• RS232 port for downloading latest software enhancements
• Cooling: Tunnel design cooling construction provides exceptional cooling efficiency while keeping electronic circuits safely out of the heated airflow
• Warranty: Backed up by a 2-year limited warranty on all components with the exception of the TIG torch and consumables which carries a 30-day duration
