The Lincoln CV 505 is a MIG/MAG welder of transformer design, with a welding current of 500 A at a 60% duty cycle and 400 A at a 100% duty cycle. The supply is 400 V, the cooling is liquid and the interconnection cable is about 15 m long. There are two working modes: synergic and manual.
What this machine is for
The 400 A in continuous work holds long runs on thick steel without breaks for cooling, and 500 A gives a reserve for passes with deeper penetration. This is a power source for a fixed station in a steel fabrication shop and in a repair plant, where heavy joints repeat.
The synergic mode shortens the setting up: you pick the wire and the thickness and the source chooses the rest. The manual mode leaves the control over the voltage and the feed on your side. The interconnection cable of about 15 m moves the feeder away from the source, so you go down with it into the structure.
Features and equipment
- Synergic mode. You pick the wire and the thickness, the source sets the rest of the parameters.
- Manual mode. You set the voltage and the wire feed yourself, with no support.
- Interconnection cable of about 15 m. A wide working reach without moving the source.
- Transformer design. A simple power circuit that copes with the conditions of the hall.
- Liquid cooling for work at high current.

What to watch out for
The product record gives a welding current above 500 A and the source description 500 A at a 60% duty cycle, so confirm the configuration before you buy. The 400 V supply needs a three phase socket, and you pick the fuse to match the draw at the upper settings.
The transformer weighs its own, the machine suits moving around the hall and not carrying between building sites, and the record gives no weight. With liquid cooling you watch the coolant level and the flow through the hoses. Run the 15 m bundle without sharp bends.
