  • Plasma Cutter Won’t Pierce Metal: Causes and Fixes

    A plasma cutter that fails to pierce metal will produce arc instability, excessive spatter, or no full penetration. This issue is typically related to air supply, consumable wear, or incorrect setup parameters. Identifying the restriction point in the system is critical for restoring proper cut initiation.

    Key Takeaways

    • Insufficient air pressure is a leading cause of failed pierce
    • Worn consumables disrupt arc focus and energy transfer
    • Incorrect amperage or travel setup prevents full penetration
    • Material thickness must match machine capability

    Problem / Context

    Plasma cutting relies on a high-velocity ionized gas stream to melt and eject metal. When the system cannot pierce, the arc may start but fail to transfer enough energy into the material. This results in surface gouging instead of a full cut-through.

    Root Causes

    • Low air pressure or flow: weak arc and poor metal ejection
    • Moisture in air supply: destabilizes plasma arc
    • Worn electrode or nozzle: reduces arc concentration
    • Incorrect amperage setting: insufficient heat input
    • Excessive stand-off distance: arc loses intensity before contact
    • Material too thick: exceeds machine rating

    Solution / Explanation

    • Verify air compressor output meets cutter requirements (pressure and CFM)
    • Install a moisture separator or dryer to remove water contamination
    • Inspect and replace consumables if wear is visible
    • Set amperage appropriate to material thickness
    • Maintain correct torch height during pierce and cut
    • Confirm material thickness is within rated capacity

    • Air Pressure Requirement: Unknown (Verify)
    • Air Flow (CFM): Unknown (Verify)
    • Amperage Range: Machine dependent
    • Maximum Pierce Thickness: Unknown (Verify)
    • Consumable Type: Model-specific

    Incorrect SettingsIncomplete pierceAdjust amperage

    Safety Notes

    Follow ANSI Z49.1 for safe cutting practices. Ensure proper ventilation and use appropriate eye and face protection rated for plasma cutting. Disconnect power before servicing consumables or air systems.

    FAQ

    Why won’t my plasma cutter pierce thick steel?

    The material may exceed the machine’s rated pierce capacity or settings may be too low.

    Does air pressure affect piercing?

    Yes. Low pressure reduces arc force and prevents molten metal from being expelled.

    How often should consumables be replaced?

    Replace when wear is visible or cut quality declines. Frequency depends on usage and material.

    Next Step

    Check air supply and inspect consumables before the next cut. Correct setup and maintenance resolve most piercing failures without equipment changes.

    A: Yes. ER70S-6 is more forgiving on dirty steel.

    Next Step

    Check your gas flow and nozzle first. If needed, switch to ER70S-6 wire and clean your material before welding.

  • Ground Clamp Replacement Guide: FGC200 200 Amp Clamp for Welding Setups

    Why this matters

    A weak ground clamp causes arc instability, poor starts, and wasted time. If the clamp is loose, corroded, or undersized for the job, the machine cannot deliver a consistent return path.

    For a simple replacement path, the FGC200 Ground Clamp 200 Amp is a verified option to check first. The key is matching the clamp to the current load and the cable setup you already run.

    When to replace the clamp

    • Arc starts are erratic
    • The clamp jaws are dirty or burnt
    • The spring tension is weak
    • The cable connection is damaged
    • You need a new clamp for a 200 amp class setup

    What to verify before you buy

    • Cable connection style
    • Lug or clamp attachment method
    • Current demand of the machine and workpiece
    • Clamp jaw condition and contact surface

    Recommended use case

    Choose this clamp if you need a straightforward replacement for a worn ground clamp in a 200 amp class setup and want a simple upgrade path without changing the rest of the lead assembly.

    Safety note

    Shut the machine off before replacing the clamp. Make sure the work lead is connected correctly and the contact surface is clean. For structural work, follow the applicable welding procedure and code requirements.

  • TIG Gas Lens Compatibility Guide: 45V26 Gas Lens for WP-17, WP-18, and WP-26 Torches

    Why this matters

    If your TIG arc is wandering, the tungsten is overheating, or shielding gas coverage is inconsistent, the gas lens setup may be the problem. A correct gas lens collet body helps smooth gas flow and improves shielding around the tungsten.

    If you are setting up a WP-17, WP-18, or WP-26 style torch, the 45V26 family is a common front-end consumable to verify first. This guide is about fitment, not guesswork. Check the torch body, tungsten size, and cup setup before ordering.

    When to replace or upgrade the front end

    • Arc starts feel unstable
    • Gas coverage looks uneven
    • Tungsten contamination happens often
    • The collet body is worn, pitted, or damaged
    • You need a setup matched to a standard TIG torch body

    What to verify before you buy

    • Torch model: WP-17, WP-18, or WP-26
    • Tungsten diameter: match the 3/32″ size if that is your setup
    • Cup size: confirm your cup and back cap arrangement
    • Collet body thread and front-end style: match the torch family, not just the size

    Recommended use case

    Choose this setup if you want a standard TIG consumable path for a common 17/18/26-series torch and you need a verified 45V26 replacement path.

    Safety note

    Disconnect power before changing TIG consumables. Verify torch and consumable fitment against the manufacturer documentation before use. For procedure-controlled welding, follow the applicable welding code and work instructions.
