PROTIG 231 DC FV is a very compact and portable pulse TIG DC welding power source. PFC technology
ensures that it can operate from 195 V to 265 V, and still produces a very stable arc, even if a 100m extension
lead is being used. When welding with an electrode, the MMA Pulse mode is particularly useful for ascending
vertical welds.
WELDING PROCESSES
TIG DC DC Standard: smooth current welding on most ferrous materials.
DC Pulse, up to 2 kHz: controls the temperature of the weld pool, which limits distortion and
means that workpieces as thin as 0.3 mm can be assembled.
MMA Standard MMA: rutile and basic electrodes (up to Ø 5 mm).
MMA Pulse, up to 500 Hz: facilitates welding in a vertical upright position (pipes/pipelines,
etc.)
OPTIMISED TIG SETTINGS
2 tacking modes :
– Spot : adjustable tacking time from 0.1 to 60 seconds on workpieces prior to welding.
– Pulse : adjustable from 0.01 to 60 seconds for thin plates prior to welding.
2 types of ignition: contactless HF or contact LIFT for electrosensitive environments.
3 trigger controls: 2T, 4T and 4T LOG.
MAXIMUM PERFORMANCE
Advanced secondary control for maximum arc stability and consistent current in all positions.
Stores up to 50 programs per process for recurring tasks.
Advanced menu for enhanced welding control.
Current and voltage display during and after welding (DMOS/QMOS)
Automatic torch detection: compatible with lamella, double button, potentiometer and Up&Down torches.
Remote controls (foot pedal or manual options) can be connected without using tools.
VRD can be activated via an internal switch to reduce open-circuit output voltage to < 35 V.
Intelligent fan management to reduce power consumption, dust ingress and noise.
IDEAL ON SITE
Accommodates extension leads up to 100 m long.
Reinforced body and anti-shock feet.
Space-saving and portable for on-site use.
Protected against overvoltage up to 400 V (PROTEC 400).
