Not Sure This Is Your Torch?
Nickel-plated and copper PT31 parts are for PT31 / LG40 style push-in torches. If your electrode or cutting tip screws into the torch, you may have a different torch type.
Before ordering, compare your torch against the four common types: PT31, SG51, AG60 and P80.

Buy PT31 Consumables
- Nickel-plated or copper options
- Standard or extended tips
- PT31 / LG40 push-in torch parts
You open a new pack… and straight away something looks off.
They’re not that usual copper colour.
They’re silver-looking.
You’re thinking:
“What the hell have I bought here… are these even the right ones?”
Before you overthink it — relax.
Some come copper.
Some come nickel-plated.
👉 Both fit the same torch.
If your setup has push-in parts, a double-ended electrode, and you have to touch the metal to start the arc…
You’re in the right place.
What You’ve Actually Got
We’re talking about those really common torches:
● PT31
● LG40
● or whatever random name got slapped on it
You’ll find them on:
● Cheap import machines
● TradeMe units
● Entry-level plasma cutters all over NZ
No pilot arc.
You’ve gotta scratch start it.
That’s your giveaway.
The Nickel-Plated Thing (Real Talk)
I didn’t even mean to buy them the first time.
Ordered a pack a couple years back… didn’t say anything about nickel plating.
They turned up and I thought:
“What the hell is this…?” Didn’t look right.
But I used them anyway.
And from actual use — not theory — just cutting steel…
They felt a bit harder.
Seemed to last a bit longer.
And yeah… I reckon they cut slightly nicer too.
Could be in my head.
But that’s what I noticed.
Quick Reality Check
Before you think you’ve found some secret upgrade… 👉 They’re not magic.
Just a slightly tougher version of the same thing.
Same torch.
Same fit.
Same job.
What I Buy Now
These days…
If I’ve got the option — I grab the nickel-plated ones.
Not because they’re wildly better.
Just because:
● They feel a bit tougher
● Don’t seem to wear out as fast
● Hold their shape a bit longer
That’s it.
Price (Don’t Overthink It)
They’re not some premium upgrade either.
Most of the time:
● Same price
● Or maybe slightly more Nothing major.
Sometimes they’re easy to find. Sometimes they’re not.
Just depends what’s around.
Do They Actually Cut Better?
From my own use…
Yeah — I reckon they cut a bit nicer.
Bit smoother.
Bit more consistent.
But be straight about it:
👉 It’s not a massive difference.
And it might just be perception.
What Actually Matters More
Your cut quality is way more affected by:
● Air pressure
● Clean, dry air
● Tip size vs amperage
● How steady your hand is
Not whether it’s copper or nickel. You can have the “better” tip… and still get a rough cut if everything else is off.
👉 If you’re running a scratch start setup like this, understanding how you’re cutting makes a bigger difference than tip material — especially on cheaper machines (see: drag tip vs standoff plasma cutting).
Where You’ll Actually Notice the Difference
If you’re doing:
● Thin steel
● Light fabrication
● Cleaner cuts That’s where I noticed it.
Nickel-plated tips seem to:
● Hold shape better
● Stay consistent longer
● Not wear out as quickly
Copper can drop off a bit faster sometimes.
Where It Makes Zero Difference
If you’re:
● Cutting rusty junk
● Doing rough jobs ● Running poor air supply 👉 You won’t notice anything.
Either will do the job.
Why They Might Last Longer
Nothing fancy.
Nickel plating is just: 👉 A harder outer surface
So you get:
● Less edge wear
● Less pitting
● Slightly better durability
But they still wear out.
No escaping that.
The Big Myth
Some people think: “Nickel-plated = better performance”
Nah.
👉 It won’t make your cutter stronger
👉 It won’t give you more power
It just helps the part last a bit longer.
That’s it.
Don’t Buy the Wrong Thing
This matters way more than plating.
People get caught out here.
They focus on: ● Copper vs nickel
And forget: 👉 The torch type
If it’s not:
● PT31 / LG40
● Push-in parts
● Double-ended electrode
It won’t fit.
Doesn’t matter what colour it is.
Quick Torch Filter
● PT31 / LG40 → push-in parts, double-ended electrode
● AG60 → everything screws in
● SG51 → tip doesn’t screw in
● P80 → bigger torch, chunky parts
If yours is push-in — you’re PT31 / LG40.
FAQ
Are nickel-plated tips better?
Slightly tougher, maybe a bit nicer cut. Not a huge difference.
Will they fit my torch?
If it’s PT31 / LG40 — yes.
Do they last longer?
From my experience, slightly.
Should I switch?
If you can get them, sure. If not, don’t stress.
Final Word
If your parts look like this…
You’re not dealing with anything fancy.
👉 Just standard PT31 / LG40 consumables — copper or nickel-plated.
Use what you’ve got.
Just make sure it actually fits your torch 👍
