Description
We are the official distributor and authorized service provider of the GYS brand in Poland.
GYS PROTIG 231L DC PFC is an advanced, ultra-compact and portable single-phase (230V) inverter welding machine for professional DC TIG welding with two arc ignition modes: HF (non-contact) and Lift Arc (contact). In addition, it allows MMA (Manual Metal Arc) welding with PULS function.
This model is distinguished by an integrated liquid cooling module (marked with an “L” in the name), which allows welding at higher currents for longer periods without overheating the TIG handle. In addition, it is equipped with PFC (Power Factor Correction), which optimizes power consumption, making the device more energy-efficient and less prone to voltage drops.
The welder offers a maximum welding current of 230 amps. The “no accessory” version means that the kit includes only the welder itself with the built-in cooling system, without the TIG handle, MMA handle, ground wire and other welding essentials.
Key features of the PROTIG 231L DC PFC welder:
DC TIG welding: High quality welds on carbon steel, stainless steel, copper and its alloys.
Two types of TIG ignition:
HF (High Frequency): Non-contact arc ignition, ideal for precision work and avoiding contamination.
Lift Arc: Occlusion by touching the tungsten electrode to the material to be welded, recommended in environments sensitive to electromagnetic interference.
Gas Post Flow Function: Adjustable gas post flow time protects the weld from oxidation and cools the electrode.
MMA welding: Capable of welding with covered electrodes up to 5 mm in diameter (rutile, basic).
MMA support functions:
Adjustable Hot Start: Facilitates arc ignition.
Adjustable Arclace: Stabilizes the arc and prevents electrode sticking.
Anti-Sticking: Prevents the electrode from sticking to the material being welded.
MMA pulse (up to 500 Hz): Facilitates welding in vertical positions (pipes, pipelines).
Integrated liquid cooling system: Allows welding at higher currents for longer periods without overheating the TIG handle.
Compact and lightweight design: Makes it easy to transport and work in various locations.
Intuitive control panel: Simple adjustment of welding parameters.
Memory of 50 programs: Ability to save favorite welding settings for each process.
2T/4T/4T LOG functions: different handle modes for greater welding compdlat.
PULSE TIG (up to 2 kHz) and SPOT functions: advanced TIG welding modes with adjustable frequency and scoring time.
Two scoring modes (SPOT and PULSE): Facilitate the tacking of thin sheets.
Automatic handle detection: Compatible with push-button, dual-button and potentiometer handles.
AIP (Adjust Ideal Position) function: Helps position the chuck before welding (in 4T and 4T LOG modes).
E-Weld function: Provides consistent welding power regardless of chuck position.
ENERGY function: Display and calculate energy consumption after welding according to standards.
PFC (Power Factor Correction): Optimizes power consumption and increases resistance to voltage drops.
Overvoltage protection: PROTEC 400 – protection up to 400V.
Application:
The PROTIG 231L DC PFC without accessories is an ideal base for professional welders who plan to do intensive DC TIG work with higher currents and need a welder with built-in liquid cooling and power factor correction. The user needs to buy a suitable liquid-cooled TIG chuck, MMA chuck, ground wire and other accessories. The welder will be suitable for precision welding work on a variety of materials in industry, workshops, assembly and other demanding environments.
