Manufacturer: R-Tech
Description
The R-Tech TIG400EXT is a power-packed 400Amp AC/DC TIG welder with 415V input, 4 AC waveforms, 9 Job memory store, True 4 way trigger latching with pre/post gas, slope up/down and start/final amps, LED display, advanced pulse welding and remote foot pedal option and a massive 60% duty cycle.
Key Features:
4 AC Waveforms
- Advanced Square Wave: fast cooling weld pool, deep penetration and fast travel speed
- Soft Square and Sine Wave: Lower arc noise, for a more traditional arc
- Triangular Wave: designed for thin alloys, reduces heat input
- HF Microstart - improved arc starting and less interference
- Lift Tig start option when welding near sensitive electronics - Automotive ECUs etc
- VRD Voltage Reduction in MMA - reduces OCV in standby for increased user safety
- Full 4-way functioning with control of pre/post flow gas, initial/final amps, slope up/down
- Generator Friendly - Recommended minimum of 7KVA
- LED display for preset and actual amperage
- MMA Anti-Stick, Arc-Force & Hot Start technology
