Tough and reliable

Suitable for gas-cooled MIG/MAG welding and carbon arc gouging, the X3 MIG Welder is a smart investment for professional welders. It is packed with energy-efficient inverter technology and delivers up to 500 A at a 60% duty cycle. The system includes several special functions for fine-tuning the start and end of your welds. The X3 MIG Welder’s stable arc guarantees high-quality welds, even with inexpensive CO2 shielding gas.

Designed and manufactured in Finland, the X3 MIG Welder is a durable choice for tough welding conditions, whether you work at a construction site, shipyard, or metal fabrication workshop. The system’s wire feeder features a fully enclosed and impact-resistant dual-skin cabinet to protect the wire spool and feed mechanism. The simple two-knob control panel is easy to use and isn’t afraid of rough handling.

Available in Africa, Asia, Australia/New Zealand, Latin America and Russia
