AI Description
BetaCapabilities
These Rehm Invertig Pro TIG welding machines deliver precision arc welding for demanding applications. The 350 AC/DC model handles 3-350A with full 100% duty cycle, while the 450 DC model provides even higher amperage. Both are industrial-grade inverter units built to IEC standards, offering stable, clean welds on aluminum, stainless steel, and other non-ferrous metals.
Industries & Uses
Manufacturers across automotive, aerospace, fabrication shops, and metal construction rely on TIG welders for high-quality joints where appearance and strength matter. They're essential for custom metalwork, repair shops, and any operation requiring precision welding on thin or exotic materials. Both machines run on standard three-phase 400V power, making them suitable for most European industrial facilities.
What to Check When Buying
When evaluating these 2013 units, request complete maintenance records and ask about electrode consumption patterns—this indicates actual usage intensity. Inspect the torch cables for cracks or burns, check cooling fans for debris, and verify the foot pedal or remote controls function smoothly. Confirm the machines have been stored dry and test the arc start reliability. Given their age, factor in potential capacitor or cooling system servicing into your budget.
