The Lorch P 5500 XT is an inverter MIG/MAG welder with a welding current of 550 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 menu is wide, with a manual mode, synergy and the XT process.
What this machine is for
The 400 A in continuous work holds long runs without breaks for cooling, and 550 A gives a reserve for thick sections and heavy steel structures. This is a power source for a production station, where both the pace and the repeatability of the parameters count.
The menu gives three ways of working. In the manual mode you set the voltage and the feed yourself. Synergy shortens the setting up to the choice of wire and thickness. The XT process is quality welding, in which the source watches the run of the arc instead of leaving everything to the hand of the welder. The liquid cooled torch stands up to long runs.
Features and equipment
- Manual mode. You set the voltage and the wire feed yourself.
- Synergic mode. You pick the wire and the thickness, the source sets the rest of the parameters.
- The XT process for quality welding. A controlled run of the arc and repeatable joints.
- A wide menu. Access to the processes and the settings from one panel.
- Liquid cooling. The circuit takes the heat from the torch at the upper settings.

- new 4 m MIG torch for 500 A, liquid cooled
- earth clamp 3 m
- power supply cable
What to watch out for
The torch from the set carries 500 A and the source gives 550 A, so at the upper settings you work in shorter spells or you add a stronger torch. The 400 V supply needs a three phase socket, and you pick the fuse to match the draw at 550 A.
The wide menu takes a moment to learn, but you can save the settings for repeatable joints and call them back. With liquid cooling you check the coolant level and the quick couplings for leaks before the start. The record gives no length for the power cable and no weight for the set, confirm them before collection.
