Rapidweld Industries

HF-unit Suitable for DC TIG Welding application-200 AMP with SMAW Power Source of any make. Light Weight, Compact & Portable for greater flexibility in operation.

• Portable & Light Weight
• Built in high frequency unit for easy arc striking in AC/DC TIG welding process
• HF on/off switch to prevent high frequency interference (In DC mode only)
• Gas flow through solenoid valve for Economical consump[tion of costly Agron gas
• Auto HF cut off if arc does not strike within 10 seconds
• Built in gas pre-flow / post-flow facility
• In built water cooling unit with HF 3000/ HF3000AD

• HF 3000 controls units are recommended for using alongwith dioded based, thyristor based or Inverter based DC rectifiers for DC TIG welding applications, for both indoor and outdoor use at project sites
• HF 2000 units are used for light and medium duty DC TIG welding applications where as HF 3000 units (bult in with water cooling unit), are used for continuous heavy duty DC TIG welding for full shift and regular production jobs
• HF 2000AD and HF 3000AD controls units are recommended for using alongwith AC power sources like RED / DH / DS / DR type transformers for AC TIG wedling applications for both indoor and outdoor use at project sites
• HF 2000AD units are used for light and medium duty AC TIG welding applications where as HF 3000AD units (built in with water cooling unit), are used for continuous heavy duty DC TIG welding for full shift and regular production jobs

• Latest High Frequency Inverter based technology with constant output current suitable for both TIG (AC & DC) and MMA welding operation
• Positive (DC+) & negative (DC-) polarity selection in MMA mode
• Option of HF ON & HF OFF in TIG mode, hence also suitable for scratch start in TIG mode
• Built HF ignition for easy arc striking.
• Welding process, mode selection and parameter adjustment by using keypad and multi function encoder provided on digital frontpanel
•  7 segment LED display for actual current display & 7 segment LED display for actual voltage display & LCD display for other parameter display setting
• Anti stick function to protect the machine from short circuit condition in MMA mode.
• CRATER OFF (2T), CRATER ON (4T), SPOT, CYCLE mode of operation (TIG).
• Available with Cleaning width control and AC offset adjustment and AC frequency setting for AC TIG welding application.
• Adjustment of pulse current, pulse frequency, pulse width, AC current, AC frequency, cleaning control and AC offset, it can meet the requirement of seam depth, width and ripple, which can prolong the using life of tungsten electrode.
• Option of Remote-control unit for setting current remotely in MMA and TIG mode
