Equipment Details

ADVANCED TECHNOLOGY MADE SIMPLE

A quality weld is always important. In some industries and applications, lives may even depend on it. If this is the challenge you face every day, choose a TIG welding machine that meets the demanding quality standards of the aerospace, motorsports, shipbuilding, education and fabrication industries.

The Aspect® 375 is the perfect choice for mission critical welds, especially on applications that must stand up to the most rigorous testing requirements.

 

AUTO OR MANUAL: THE CHOICE IS YOURS

Effortless arc control

Extremely fast arc response and stability for the smoothest and most efficient weld possible.

Simplicity when you want it

Activate Intellistart™ technology to automatically provide for softer starts and minimal distortion on thinner materials and hotter starts required for thicker materials. Optional AC Auto Balance® technology offers simplicity by automatically providing the optimal mix of cleaning and penetration when welding aluminum.

Customization when you need it

AC Wave Shape control enables you to customize the arc for critical aluminum welding requiring:

  • A higher degree of penetration on thicker materials.
  • Increased cleaning action in breaking through heavy oxide layers.
  • Narrower arc profile enhancing control around corners and other tight configurations.

Net Weight 235.00 (106.60 kg)
  • AC WAVE SHAPE CONTROLS
    AC FREQUENCY 40-400 Hz

    A lower frequency results in a wider bead.
    A higher frequency results in a more focused bead.

     

    AC BALANCE CONTROL 35-99% (EN%)

    A lower AC Balance (EN%) results in an arc with increased cleaning action.
    A higher AC Balance (EN%) results in an arc with higher penetration.

     

    ELECTRODE POSITIVE (EP) AND NEGATIVE OFFSET (EN) 2-375 Amps EP
    2-375 Amps EN
    A higher Electrode Positive (EP) current value results in intensified cleaning action.
    A higher Electrode Negative (EN) current value results in intensified penetration.

     

    PULSE FUNCTIONS

    AC PULSE FREQUENCY 0.1-25% of AC output frequency
    setting in pulses per second
    DC PULSE FREQUENCY 0.1-2,000 pulses per second
    Alternating the current between peak and background helps better manage heat input and minimize material distortion.
    Provides for better arc control and faster freezing for uphill welding.
    Helps moderate filler metal deposition at low pulse frequencies (less than 10 pulses per second).

     

    AC WAVE FORMS

    SOFT SQUARE Increased puddle control
    SINE A soft sounding arc
    SQUARE Faster travel speeds
    TRIANGULAR Reduced heat input on thinner materials. Also provides for better cleaning on anodized applications
