HALANSM® V4540 Shield V4540 Swirl Gas Cap .11.833.111.156 for Kjellberg Plasma Cutting Torch
HALANSM® HLN-V4540 is an aftermarket plasma shield (swirl gas cap) made of copper alloy, built for Kjellberg PB-S70 and PB-S75 plasma cutting torches to deliver stable arc and clean cuts.
Looking for a V4540 swirl gas cap for Kjellberg PB-S70 / PB-S75? This aftermarket replacement features a copper alloy body, radial vented face, and threaded outer profile to maintain vortex gas flow, protect the torch seat, and support O2, air, N2, and ArH2 cutting processes. Provide your torch model and original part number for fitment check.
Product Overview
The HALANSM® HLN-V4540 installs as the outer shield and swirl gas cap at the front of the Kjellberg PB-S plasma torch. Its vented front face and internal swirl geometry direct plasma gas into a controlled vortex around the arc, stabilizing the plasma jet and minimizing dross. The copper body provides heat dissipation and mechanical protection for the electrode and nozzle during sustained cutting.
Key Advantages
Product Overview
Stable Vortex Flow
Vented radial face and internal swirl geometry maintain consistent gas rotation for a focused arc and clean edges.
Copper Alloy Body
Copper construction offers high thermal conductivity and resistance to thermal wear under continuous cutting duty.
Threaded Seating
External threads and a machined seat align the cap squarely with the torch body. Hand-tighten only; do not over-tighten.
Batch Inspection
Each lot is checked for dimensional tolerance and vent integrity. Store in a dry, clean environment away from moisture and contaminants.

Compatible Equipment / Application
Compatible aftermarket replacement for Kjellberg PB-S70 and PB-S75 plasma cutting torches using the V4540 / .11.833.111.156 shield (swirl gas cap). This is an aftermarket part, not original Kjellberg equipment and not factory authorized. Provide your torch model and original part number for fitment check before ordering.
Selection Notes
Use HLN-V4540 only in PB-S70 / PB-S75 stacks. Do not interchange with HiFocus / PerCut swirl caps (G4020, G4350) or PA-series gas guides (V101): the seat profile, thread, bore, and current rating differ. Installing the wrong cap breaks the vortex, causes arc wander, and accelerates electrode and nozzle wear.
Installation and Handling
· Power off the plasma system and release gas pressure.
· Remove the worn shield, swirl ring, nozzle, and electrode.
· Clean the torch seat and threads; inspect O-rings and sealing surfaces.
· Install the electrode, nozzle, and swirl ring in order.
· Thread HLN-V4540 onto the torch by hand; do not over-tighten copper threads.
· Run a low-current test cut to verify arc stability and gas flow.
Frequently Asked Questions
Which Kjellberg torches fit HALANSM® HLN-V4540?
It fits Kjellberg PB-S70 and PB-S75 plasma torches as an aftermarket replacement for V4540 / .11.833.111.156. Share your torch model and OEM number for final fitment confirmation.
What material is the V4540 shield made of?
HLN-V4540 uses copper alloy with a radial vented face for heat dissipation and gas swirl. It is an aftermarket part, not original Kjellberg.
Does V4540 support O2 and air plasma?
Yes. HLN-V4540 supports O2, air, N2, and ArH2. Always match the electrode and nozzle to the selected gas; O2 and air nozzle bores are not interchangeable.
Why does cut quality drop after installing the shield?
Common causes are a mixed-family cap, dirty torch seat, clogged vents, or over-tightened threads. Clean the seat, confirm V4540, and perform a low-current test cut.
What dimensions should I confirm before ordering?
Confirm outer diameter, height, thread pitch, and bore for your PB-S torch variant. These are listed as confirm-exact-specs until your torch model is verified.
How should I store spare swirl gas caps?
Keep spares in original packaging, dry and dust-free. Avoid oil, moisture, and stacked metal that could deform the bore or seat.
