PROTIG 221 DC FV
The versatile PROTIG 221 DC FV (220 A) is a compact, portable, dual-process appliance for DC TIG and MMA
welding processes. This machine is fitted with PFC technology which has numerous advantages; it is very
energy efficient and can work reliably with very long power cables, even ones over 100 metres long.
Its secondary regulation system ensures optimal arc stability as well as a constant
current in all welding positions.
The DC TIG-welding mode ensures high-quality welding on all ferrous materials, such as
steel, stainless steel, copper and its alloys.
DC Pulsed TIG welding up to 2 kHz means users can control the temperature of the
weld pool, limit deformations and join sheet metal as thin as 0.3 mm.
Its spot-welding feature can be set anywhere between 0.1 – 25 sec offering fast and
precise spot-welding on thin sheet metal.
The machine is equipped with two different ignition types: contactless HF (highfrequency) ignition or Arc-Lift ignition with contact for electro-sensitive environments.
Users can also enjoy three separate trigger managements systems: 2T, 4T and 4T LOG.
An automatic torch-detection feature means that this device is compatible with trigger,
double-button and potentiometer torches.
OPTIMISED DC WELDING
MAXIMUM PRODUCTIVITY
Stores up to 10 welding programs per process.
The advanced menu settings offer optimal welding control.
PFC (Power Factor Correction) technology means that this machine is compatible with
power cables up to 100 metres long.
FV (Flexible Voltage) technology guarantees a stable electric arc, even in the event of a
mains-voltage variation (85 – 265 V) or when powered supply by a battery-based power
source.
The current and voltage are displayed during and after the welding process (DMOS/QMOS).
Remote control connections (manual or pedal)
Reinforced bodywork and anti-shock pads.
Compact and easy to move around the work site.
Protected against over-voltages up to 400 V
