Welding Machines – How to Choose the Right Welder for Your Projects

Types of welding machines

Inverter stick welders like the AGM Aparat za zavarivanje IW-120 are ideal for home workshops and field work thanks to their compact size and low power consumption. TIG welders such as the STANLEY Aparat za zavarivanje tig deliver precise welding of thin materials and stainless steel but require more experience. MIG/MAG welders are best suited for production work as they enable continuous welding without changing electrodes.

Inverter vs transformer welders

Inverter models from brands like ESAB and DeWalt offer significantly lower power consumption and maintain a stable arc even with weaker electrical supply. Transformer welders are more robust and durable in industrial settings but are heavier and require quality installation. For occasional home use, inverters are always the better choice.

Machine power and material thickness

Welders with 120-160A amperage meet most hobbyist needs and can weld steel up to 6-7mm thickness. Professionals working on structures of 10mm and above need machines rated 200A and higher. Note that declared power always refers to maximum output – actual working power is 20-30% lower.

What to check before buying

Verify that the machine has thermal protection preventing overheating during extended use – brands like GYS and WOMAX include this feature as standard. Hot start function makes arc ignition easier, while anti-stick prevents electrode sticking. Quality machines from Ingco, Villager and Wurth come with carrying straps and protective masks included.

Duty cycle and real-world usage

Duty cycle indicates how many minutes within a ten-minute period the machine can operate at maximum power. A rating of 60% at 120A means the welder can run for 6 minutes, then must cool for 4 minutes. For intensive work, choose machines with an 80% cycle or higher.
