PowerTIG 255EXT

The PowerTIG 255EXT stands out for its powerful performance and advanced AC/DC TIG features, offering superior control, duty cycle, and versatility for demanding professional welding applications.

In fact, the PowerTIG 255EXT not only has a long list of competitive features but also unique features that distinguishes it from the competition. You'll find surprisingly competitive performance when comparing feature to feature against the competition such as memory, pulse and wave forms thanks to the digital microprocessor. When you compare the additional features and the price advantage the welder offers such as the advanced AC pulse and stick performance features such as hot start and arc force control , the PowerTIG 255EXT really stands on it's on.

Advanced pulse is a new feature introduced on the digital PowerTIG  units which improves top and low end performance on Aluminum.It can be set up to increase penetration on thick aluminum up to 25% over what is traditionally accepted as the maximum limit for the maximum output of the welder. Two "Easy Start Up" modes also add to the units versatility while keeping operation simple.

The unit also excels as a stick welder featuring hot start time, hot start intensity and arc force control adjustments, making it a perfect welder for E6010 or E7018 welding. Everything on the AC/DC pulse TIG welder has been carefully designed for maximum life and repairability down the road with componentized design and IGBT module components from name brand manufacturers. This make diagnosis and repair a simple and easy process. The spot weld timer feature allows the operator to make perfect, consistent spot welds when tacking up or welding sheet metal.

The unit also has a more convenient way to purge gas and set gas without initiating arc flow with a dedicated purge button. Most importantly the PowerTIG 255EXT operates on 120V or 240V. Maximum output during 120V operation is 150 Amps for TIG, and 120 Amps for stick.

  • Now with HV Start. This is an advanced type of HF arc start with electronic control rather than older point gap style starts that required maintenance.
  • Now with Fan-On-Demand.  The fan now runs when it is needed, starting on arc start and terminating as the welder cools down enough after the arc stops. 

Features:

  • Digital microprocessor control
  • Heavy-Duty IGBT Power Modules increase reliability and performance
  • True low amp operation down to 3 amps DC and 5 amp AC

  • Heavy Duty High Frequency design reduces maintenance issues and improves start reliability
  • No hidden menus to access or complicated set up routines
  • Simplified menu design allows settings to be quickly selected and adjusted
  • Easy Start Up feature in AC or DC modes to make setup quick and easy for the beginner, or the advanced user
  • Pulse up to 500Hz in DC, 250 Hz AC
  • 10Hz Advanced AC Pulse mode improves penetration on thicker metals, and can reduce warping and burn through on thinner metals
  • Arc force control, Hot start time, Hot start intensity settings for Stick welding to improve performance
  • VRD function to help reduce chance of shock or electrocution in areas where a VRD is required or needed for stick welding
  • Built in receptacle for PowerCool 300 water cooler
  • Full time fan for maximum duty cycle operation
  • 120V/240V operation
  • Spot Weld Timer
  • 6010/Cellulose Stick welding capability
