TD SL60 & SL100 Gouging Consumables FAQs

Plasma gouging consumables remove metal from the surface of a workpiece instead of cutting through it; these answers help you choose, fit and look after them.

Why do the small O-rings on the torch matter, and how should I look after them?

O-rings seal the gas paths in the torch head and around the consumables. Plasma maker manuals say to examine them whenever you change consumables and to replace any that are damaged. A worn or missing seal can leak gas and lead to poor arc starting or poor cut quality.

Where a seal looks dry, makers say to apply only a thin film of the silicone lubricant they specify, so that it looks shiny. Too much lubricant can prevent gas flow, so wipe off any excess with a clean, lint-free cloth, and keep lubricant off electrical contacts. Use only the lubricant your manual names, follow its instructions on which parts to lubricate, and replace seals with ones that match your torch type.

Does the quality of the compressed air affect gouging consumables?

Yes. Plasma maker guidance says moisture, oil and other contamination in the air supply can significantly reduce consumable life and cut quality, and can even harm the torch. Poor gas quality also reduces cutting and gouging performance.

Use a clean, dry supply. Built-in filters remove some moisture and dirt, but where air passes through long lines, tools that add oil, or humid conditions, makers recommend extra filtration close to the machine. Check the filter element and bowl regularly and replace the element as your manual says. Keep the pressure within the range in your manual. If consumable life suddenly drops, check the air supply first.

Is it safe to change consumables with the machine switched on?

No. Switching off at the machine alone may not remove the shock hazard if it is still connected to the supply. Plasma makers say the power supply contains dangerous voltages and that electric power should be disconnected before maintenance, with any line disconnect kept off until the work is finished.

Isolate the supply, then let the torch cool, as parts stay hot after gouging and can cause burns. Where the machine has a torch lock or disable switch, use it as an extra step, but do not rely on it or on any interlock instead of isolating the supply. Refit parts in the right order and tighten them as the manual describes, and follow the maker's instructions for your torch.

How are gouging consumables different from cutting consumables?

Gouging consumables are a separate family from cutting ones. Plasma makers publish distinct gouging parts, and the tip shape and shield are designed to remove metal from the surface rather than cut through it.

Gouging parts also come in different styles. Some are aimed at controlled, shallow removal and light washing, some at heavy removal and deep profiles, and some at very small removals at low current. Gouging shields are intended to protect the tip from molten metal, so use the tip and shield combination your torch manual lists. Check your manual for the parts your torch is designed for, and keep gouging and cutting parts clearly separated.
