How to choose a welding machine

✅ Why Choose Carefully

There welder It is an essential tool for working on iron, steel and other metals. Whether it is small household repairs or structural welding in an industrial setting, it is important to choose a model suitable for type of work, thickness of materials, type of welding and level of experience. A correct choice ensures quality results, greater safety and machine durability.

🔍 Types of Welding Machines

🔌 MMA (electrode) welding machine

The most versatile and widespread, suitable for welding iron, steel, stainless steel and cast iron. Easy to use and robust, it works with coated electrodes. Perfect for outdoor and structural work. Does not require gas.

🔥 MIG-MAG (continuous wire) welder

Ideal for long jobs and thin materials. Uses a continuous wire and shielding gas (argon or CO₂). Provides clean and fast welds. Excellent for light carpentry, bodywork and sheet metal welding.

⚡ TIG Welder

For precision welding on stainless steel, aluminum, copper and light alloys. Uses tungsten electrode and inert gas. Requires more experience but guarantees very high quality and finish.

🛠️ Multifunctional welder (combined inverters)

2 in 1 or 3 in 1 models that combine MMA, MIG and TIG. Ideal for those who work on multiple materials and are looking for versatility in a single machine.

🛠️ What to Consider When Choosing

Type of material to be welded

Iron and carbon steel → MMA or MIG
Stainless steel or aluminum → TIG or MIG with special wire
Thin sheet metal → MIG or TIG

Metal thickness

Up to 3 mm → 100–160 Ampere
3 to 6 mm → 160–200 Ampere
Over 6mm → 200+ Amps

Experience Level

Beginners → simple MMA or MIG inverter welders
Advanced users → TIG or multifunctional welding machines with detailed adjustments

Power supply

Single phase 230V → for domestic use and light workshops
Three-phase 400V → for industrial use and high intensity welding

Additional features

Digital inverter for greater arc stability
Hot Start, Arc Force, Anti Stick
Forced cooling for intensive work cycles

Portability and convenience

Handles, wheels or cases included
Variable weight: from 4-5 kg for laptops up to over 20 kg for industrial models

👨🏭 Which Welder to Choose Based on Use

For small household or DIY jobs

→ Compact MMA inverter welder 120–160A, with 2–3 mm electrodes

For welding on sheet metal or in bodywork

→ MIG welding machine with flux cored wire or gas, power from 160–180A

For aesthetic welding and on special metals

→ TIG DC or AC/DC welding machine for stainless steel and aluminum

For professional workshops and construction sites

→ Combined MIG/MMA/TIG multifunction welding machine, with digital display and forced ventilation
