Trafimet EXPRESCUT A101 Plasma Cutting Torch

A 100 A air plasma torch for HF-start power sources

The Trafimet EXPRESCUT A101 is a manual plasma cutting torch for power sources with high-frequency arc starting. It is rated 100 A at 60% duty cycle and 75 A at 100%, and the technical sheet gives a cutting thickness of 25 to 30 mm. It is often used as a replacement torch on plasma machines built around the Trafimet A101 pattern, as well as on new systems.

The torch runs on compressed air at 5 bar with a flow of 180 l/min, conforms to EN 60974-7 and is supplied with a 6 m cable in four machine-side versions.

Consumables for cutting and gouging

The sheet lists contact-cutting and drag-cutting tips of the PD0101 series from 30 A (0.8 mm orifice) to 140 A (1.9 mm), long tips PD0111 and PD0117 for extended reach, a 3.0 mm gouging tip PD0101-30, electrodes such as PR0101, diffusers PE0101 and PE0103, nozzles PC0109 and PC0113 with long-life versions, and stand-off guides CV0008 to CV0039. A circle cutting guide kit CV0022 is available.

Match the tip orifice to the cutting current: an oversized tip gives a wide, bevelled kerf, while an undersized one wears quickly. Replace electrode and tip together when the electrode pit is deep.

Checking compatibility

The A101 is an HF-start torch, so it is not interchangeable with non-HF contact-start torches such as the EXPRESCUT S series. Confirm the machine connection, the pin assignment for the central adaptor and the air supply quality; oil or water in the air shortens consumable life. Clean, dry air at 5 bar is required.

Stand-off guides keep the tip at a constant height above the plate, which improves cut squareness and protects the tip from double arcing. Drag cutting with a dedicated drag tip is easier for new operators on thin sheet, while stand-off cutting is preferred on thicker plate. For gouging, the gouging tip and a shallow torch angle remove welds or defects without a grinder.

Before starting, purge the torch with air for a few seconds after changing consumables, check that the safety contact in the head closes when the nozzle is tightened, and confirm the pilot arc settings on the power source.

Keep a record of the torch code and consumable codes on the machine, since several plasma torches look similar but use different heads, tips and electrodes that do not interchange.
