The PROTIG 231L DC PFC is a pulsed DC TIG welding generator with an integrated cooling unit. Its PFC technology allows it to operate from 195 V to 265 V and achieve a very stable arc even on 100 m site extension cords. In stick electrode welding, its Pulsed MMA mode facilitates vertical-up welding.
2 welding processes available with this unit:
-TIG DC
Standard DC: welding with smooth current on the majority of ferrous materials.
Pulsed DC up to 2 kHz: controls the temperature of the weld pool, limits distortion and enables the joining of thin sheets from 0.3 mm.
2 tacking modes:
- Spot: adjustable tacking from 0.1 to 60 seconds for parts before welding.
- Pulse: adjustable tacking from 0.01 to 60 seconds on thin sheet metal before welding.
2 arc starting types:
- HF non-contact
- LIFT contact start for electrosensitive environments. 3 trigger modes: 2T, 4T and 4T LOG.
Advanced secondary regulation for optimal arc stability and constant current in all positions.
Memory storage of up to 50 programs per process for repetitive tasks. Advanced menu for optimal welding control.
Current and voltage display during and after welding (DMOS/QMOS)
Automatic torch detection: compatible with blade-type, dual-button, potentiometer and Up&Down torches.
Remote controls (foot pedal or manual, optional) connectable without tools.
VRD activatable via an internal switch to lower the open-circuit output voltage to < 35 V.
Intelligent fan management to reduce power consumption, dust intake and machine noise.
MMA
Standard MMA: rutile and basic electrodes (up to Ø 5 mm).
Pulsed MMA up to 500 Hz: facilitates vertical-up position welding (pipe fittings/pipeline…)
