Close cutting applications such as lug and attachment removal are typically done using oxyfuel, carbon arc gouging, or traditional plasma cutting tools. The new Powermax® flush cutting process now offers a more efficient process for these operations.
Typical flush cutting applications include:
- Removing lugs, pad eyes and temporary weld supports
- Material washing
- End cap removal
- Rat hole cuts in I and H beams
- Bolt and rivet washing
- Casting sprue removal
- Post tension cable tail cuts
- Wearable part removal/replacement
Flush cutting with plasma vs. oxyfuel
Plasma requires less overall pre-processing time than oxyfuel – no gas setting, purging or preheating – increasing the efficiency of the operation. And, unlike oxyfuel, plasma can be used to remove stainless steel attachments.
In addition, cutting with a Powermax® system significantly reduces the heat affected zone (HAZ)—about 10X less than when using oxyfuel. This is especially useful in flush cutting applications, and provides a number of important advantages:
- The ability to safely cut closer to the base material minimizes the need for secondary grinding
- Cutting closer to the base takes less material from the attachment, increasing the potential use, and reuse, of the attachments

Flush cutting with plasma vs. carbon arc gouging
With carbon arc gouging, the weld on both sides needs to be removed, requiring multiple passes and additional time on the job. The Powermax flush cutting process allows operators to remove lugs and attachments in a single cutting pass.
Flush cutting with plasma is also a quieter and less smoky process, which can improve the overall industrial hygiene of any shop or yard.
Flush cutting with plasma vs. traditional plasma cutting
The patented geometry of FlushCut™ consumables places the plasma arc in the ideal location for flush removals when compared to the arc delivery of a standard plasma cutting process. The optimized arc delivery with FlushCut consumables results in less post secondary grinding and material repairs.
Once the lug or attachment has been removed, turn the amperage down on the system and use the FlushCut process to wash away any residual ...
FlushCut removal process
The FlushCut removal process leaves approximately 3/16" of material or less on base after cutting a lug or attachment.
