PATON ProTIG-315
The PATON ProTIG-315 digital inverter welder is designed and optimized for AC/DC TIG arc welding (with inert shielding gas) as well as manual electrode welding (MMA DC).

The Professional series is designed for professionals seeking equipment with a compact design and an ideal balance of portability and performance, delivering full current power in smaller dimensions.

It is the ideal solution for AC and DC welding across a wide variety of materials:

Aluminum and aluminum alloys (TIG AC)

Steel and stainless steel

Non-ferrous metals and copper alloys (TIG DC)

Welding with coated electrodes (MMA)

Additionally, it features RIV (SPOT) mode for spot welding.

The PATON ProTIG-315 inverter welder ensures:

Contactless Arc Ignition (HF)

Stable and continuous electric arc

High Quality Welding

Easy Handling

The machine also includes protection against drops and overvoltage, and thanks to the increased transformer frequency, its weight and dimensions are significantly smaller compared to similar machines, without compromising performance.

Main Welding Methods:

TIG AC/DC (Direct / Alternating Current)

MMA (Direct Current)

RIV (spot welding function)

Main advantages of PATON equipment:

European-Made Construction

Electronic thermal protection system to prevent overheating of all components

Reliability thanks to IGBT technology

Capable of operating with long extension cords and generators

Pulse welding (PULSE)

Improved arc stability

2T / 4T modes and gas cleaning function

Surge protection and voltage stabilization system for operation from 320V to 440V

Up to 50% lower energy consumption compared to conventional sources

Ideal melting and perfect weld formation regardless of welding position

The ProTIG series features a compact design and innovative technological solutions that enhance durability.

Inverter reliability in dusty or humid environments is enhanced by:

relocating electronics to a separate chamber

additional high-quality varnish coating on electronic components
