LT100 vs. LTM100: Manual Torch vs. Machine Torch
LT100 and LTM100 belong to the same broader plasma torch family but should be treated as separate complete products.
| Feature | LT100 | LTM100 |
| Operation | Manual / Handheld | CNC / Mechanized |
| Torch Geometry | Handheld torch | Straight machine torch |
| Start Control | Operator trigger | Machine controlled |
| Mounting | Handheld | Fixed torch holder |
| Torch Height | Operator controlled | CNC / THC controlled |
| Main Application | Manual cutting | Automated cutting |
Some consumables may be shared between related torch families.
However, complete torch heads, handles, machine bodies and cable assemblies should not automatically be treated as interchangeable.
For website internal links, use clear anchor text such as:
LT100 Manual Plasma Cutting Torch
and
LTM100 CNC Plasma Cutting Torch
rather than describing both products simply as LT100.
How the LT100 HF Plasma Cutting Torch Works
The LT100 works as part of a complete plasma cutting system consisting of the plasma power source, torch, compressed-air supply and work connection.
Compressed air passes through the torch head, diffuser, electrode and cutting nozzle.
Electrical energy ionizes the gas and forms a high-temperature plasma arc.
The cutting nozzle constricts this arc into a concentrated plasma jet that melts electrically conductive metal while high-velocity air removes molten material from the kerf.
High-Frequency Arc Starting
The LT100 uses HF ignition.
A high-frequency electrical signal helps establish the initial plasma arc without requiring the cutting nozzle to mechanically strike the workpiece.
The plasma power source must therefore support a compatible HF starting system.
HF, non-HF and back-striking plasma torches should not be treated as automatically interchangeable.
Why Choose the LT100 for 100A Manual Plasma Cutting?
The LT100 is designed for professional manual cutting applications requiring more current capacity than lower-output LT50 and LT70 platforms.
100A Rated Current
The LT100 is rated at 100A.
The torch should be paired with a compatible plasma power source and operated within its verified current range.
60% Duty Cycle
The current specification lists a 60% duty cycle at 100A.
Actual thermal load can also be influenced by:
Operating current
Ambient temperature
Arc-on time
Airflow
Number of starts
Consumable condition
Do not operate the torch above its verified rating simply because the plasma power source can provide more current.
Air-Cooled Construction
The LT100 does not require a separate liquid-cooling circuit.
Compressed air functions as the process gas and also contributes to heat removal from the torch front end.
6 m Standard Lead
The standard 6 m torch lead provides practical working reach for fabrication shops, industrial maintenance and repair applications.
LT100 Connection Options
The LT100 platform is available with several rear-connection configurations.
Current options include:
1/8G
1/4G
M14×1
M16×1.5
Central Adapter
These options allow distributors and equipment manufacturers to support different plasma power-source interfaces.
A connector that physically fits does not automatically confirm electrical compatibility.
The complete torch interface must be checked.
How to Check LT100 Plasma Cutter Compatibility
Do not select a replacement LT100 only because the plasma cutter is rated at approximately 100A.
Confirm HF Starting
The plasma power source must support an HF torch system.
Confirm Rated Current
The LT100 is rated at 100A.
The power source and consumables should be operated within the verified torch range.
Confirm the Power and Gas Connection
Check whether the machine requires:
1/8G
1/4G
M14×1
M16×1.5
Central adapter
Confirm the Pilot-Arc Connection
Different plasma cutters may use different pilot-arc arrangements even when the main torch connection appears similar.
Confirm Trigger Wiring
The trigger/control circuit must match the plasma power source.
Information to Provide for Compatibility Confirmation
For replacement orders, provide:
This is more reliable than selecting the torch by amperage or connector appearance alone.
LT100 Standard Cutting Tips
The LT100 consumable platform includes several standard cutting-tip diameters.
Ø1.1 mm Cutting Tip
INWELT Code: IJWV0617-11
Reference: PD0101-11
Ø1.4 mm Cutting Tip
INWELT Code: IJWV0617-14
Reference: PD0101-14
Ø1.7 mm Cutting Tip
INWELT Code: IJWV0617-17
Reference: PD0101-17
Different nozzle diameters are intended for different operating conditions.
The correct tip should be selected according to:
Cutting current
Plasma power source
Material
Front-end configuration
Required cutting process
Do not select a nozzle only because it physically fits the torch head.
Which Cutting Tip Should Be Used at 100A?
The current LT100 consumable family includes Ø1.1 mm, Ø1.4 mm and Ø1.7 mm cutting tips.
Comparable 100A HF torch platforms commonly associate an intermediate nozzle size with approximately 100A operation.
However, INWELT should publish a final amperage-to-nozzle chart only after confirming its own engineering and cutting-test data.
The strongest future consumable table should show:
| INWELT Code | Tip Diameter | Recommended Current | Electrode | Shield / Retainer | Process |
| Verified Code | Verified Size | Verified Current | Matching Part | Matching Part | Cutting Mode |
This provides more useful first-party information than generic statements such as “multiple nozzle sizes available.”
LT100 Extended Cutting Tips
The LT100-related consumable family also includes extended cutting tips.
Current parts include:
IJWV0673-14 / PD0117-14 – Extended Tip Ø1.4 mm
IJWV0673-17 / PD0117-17 – Extended Tip Ø1.7 mm
The wider family also includes an extended 50A tip configuration.
Extended tips can provide additional access where a standard-length consumable cannot easily reach the cutting area.
Use extended tips only with the corresponding electrode and front-end consumables.
LT100 Standard Electrode
The standard electrode is:
INWELT Code: IJWC0617
Reference: PR0101
The electrode transfers electrical energy through the torch and gradually wears during repeated arc starts and cutting.
Replace the electrode before excessive center wear causes:
Difficult arc starting
Unstable plasma arc
Accelerated nozzle wear
Inconsistent cutting
Do not grind or modify a worn electrode to extend its service life.
LT100 Extended Electrode
The extended electrode is:
INWELT Code: IJWC0672
Reference: PR0116
This component is intended for compatible extended-tip configurations.
Do not mix a standard electrode and extended cutting tip unless the combination has been technically verified.
LT100 Gas Diffuser
The current gas diffuser is:
INWELT Code: IJWG0617
Reference: PE0101
The diffuser controls process-gas distribution around the electrode and cutting nozzle.
Correct airflow helps maintain:
Arc stability
Consumable cooling
Plasma-jet shape
Cutting consistency
Replace the diffuser if it becomes cracked, distorted, burned or heavily contaminated.
LT100 Outside Nozzle and Retaining Components
The LT100 consumable family includes:
IJWT0677 / PC0111 – Outside Nozzle
and
IJWT0691 / PC0130 – Contact Nozzle Retaining Cap
These components help protect and position the internal consumable stack.
Replace front-end components if they show:
LT100 Stand-Off and Contact-Cutting Accessories
The LT100 platform includes several front-end positioning accessories.
Current parts include:
IJTN0069 / CV0014 – Four-Point Spacer
IJTN0078 / CV0012 – Double-Point Spacer
IJTN0077 / CV0011 – Spacer Spring
IJTN0089 / CV0023 – Contact-Cutting Spacer
Stand-Off Cutting
Stand-off accessories help maintain a controlled distance between the cutting nozzle and the workpiece.
Correct stand-off can help protect consumables and maintain plasma-arc geometry.
Contact Cutting
Contact-cutting components use a different front-end relationship with the workpiece.
Do not drag an exposed standard cutting nozzle directly across the material unless the specific consumable configuration is designed for contact cutting.
LT100 Torch Head and Hand-Control Components
The LT100 manual torch system includes serviceable torch-head and handle components.
Current parts include:
IJWA0606 – Plasma Torch Head
IJGU0697 / EA0131 – Silicone O-Ring
IJHW0046 – Manual Plasma Handle
IJIK0733 – Trigger Protection Component
IJIR0081 – Trigger
IJIK0805 – Handle Joint
These replaceable components allow distributors and repair companies to service the torch without replacing the complete assembly every time a single component is damaged.
LT100 Cable Assembly Options
The LT100 manual-torch family includes dedicated cable assemblies.
Current examples include:
IJWO00210077-00 – LT100/LT101 / 10 mm² / 6 m / 1/8G
IJWO00210071-00 – LT100/LT101 / 10 mm² / 6 m / Central Adapter
Machine-torch cable assemblies should be presented on the corresponding LTM product page rather than mixed into the primary LT100 manual-torch table.
This keeps the LT100 product entity clear for both professional buyers and search engines.

What Metals Can the LT100 Plasma Torch Cut?
When paired with a compatible plasma cutting power source, the LT100 can be used to cut electrically conductive metals such as:
Mild steel
Carbon steel
Stainless steel
Aluminum
Copper
Brass
Galvanized steel
Actual cutting speed, edge quality and practical thickness vary according to the complete plasma system.
How Thick Can a 100A LT100 Plasma Torch Cut?
The plasma torch alone does not determine one universal maximum cutting thickness.
Actual cutting capacity depends on:
Plasma power source
Input power
Material
Actual cutting current
Cutting-tip diameter
Air pressure
Airflow
Travel speed
Torch-to-work distance
Consumable condition
Required edge quality
Professional plasma specifications normally distinguish between three different performance levels.
Recommended Cutting Capacity
Material thickness that can be cut productively with suitable speed and edge quality.
Maximum Cutting Capacity
Thicker material that can still be cut at reduced speed.
Severance Capacity
The maximum thickness that can be separated, normally with lower edge quality.
Specific LT100 thickness figures should therefore be published only when supported by an INWELT complete-system cutting test.
Build an INWELT LT100 Cutting Chart
A first-party LT100 cutting chart would be one of the strongest technical and GEO additions to this product page.
Recommended fields include:
| Parameter | Data to Publish |
| Material | Mild Steel / Stainless Steel / Aluminum |
| Thickness | Tested thickness |
| Current | Actual tested current |
| Tip Code | INWELT part number |
| Tip Diameter | mm |
| Air Pressure | bar |
