  • Page 2 The air regulator/filter supplied with the CF-45P machine provides the minimum level of filtration. However, we strongly recommend the WELDCLASS PLATINUM Z-20 high-performance air filter, available as an optional accessory from your Weldclass distributor. This attaches to the inlet of the existing regulator/filter and provides excellent filtration down to 1-micron.

    Moist or dirty air will significantly reduce cut quality and consumable life. The Cutforce 43P is supplied with a basic air filtration/moisture separator to assist with providing suitable air supply. The moisture separator is self-draining, the Air Filter Moisture Drain Tube exits out the bottom of the clear Air Filter Bowl.

    6. Compressed air will continue to flow through the torch for several seconds after the cutting stops. In this post-flow mode, the arc can be restarted immediately by depressing the torch switch. Trigger Retaining Cap Tip / Nozzle © Weldclass 2020 | E.&O.E. Figure 10...

  • Page 14: Travel Speed

    Note: The speeds given here are typical for best quality cuts. Your actual speeds may vary depending on material composition, surface condition, operator technique, etc. Air cutting typically produces a rough face on stainless steel and aluminium. © Weldclass 2020 | E.&O.E.

  • Page 15: Piercing The Work Piece

    To make a square-edged cut along an inside diameter of a circle, the torch should move counter clockwise around the circle. To keep the square edge along an outside diameter cut, the torch should travel in a clockwise direction. Figure 13 © Weldclass 2020 | E.&O.E.

  • Page 16: Reducing Dross For Clean Cuts

    Usually it will need to be removed by grinding. When cutting troublesome steel, it is sometimes useful to reduce the cutting speed to produce ‘low speed dross’. Any resultant clean up can then be accomplished by scraping, not grinding. © Weldclass 2020 | E.&O.E.

    In addition to this, this machine has a pilot arc controller system. If the main arc cuts out and the torch remains to be triggered, the pilot arc will reignite. This is useful for cutting discontinuous workpieces like mesh or grids. © Weldclass 2020 | E.&O.E.
