Never use a plasma torch by hand at an angle, that’s how you chew a directional channel into the electrode’s cone, carefully hover the tip an inch from surface and then go down to contact closer. If you do this video’s technique you’ll just chew through electrodes and cut through the metal slower.

Whenever you see a dude working a metal tube with a plasma cutter, while wearing a Hawaiian shirt, you must respect that dude!!!!
Great tip!

Thin metal this is fine like this, 3/8” and thicker to your machines capacity travel while piercing through the scrap side if available until you blow through, then move to cut line. Any CNC fuel cutting on thick materials will always require a good distance of travel while piercing, traveling keeps the slag spraying upwards to the backside of nozzle preventing any blowback into the nozzle.

Actual hypertherm gives hight for piercing at 90 depending on material thickness

Learned this the hard way in welding school 🔥 no beuno 🙅‍♂️ good important tip man 👏

Pre drill 8mm hole to prevent flash back

Great welding shirt, you must be a professional !

[douglaspost]

If you're trying to blow a hole through something like that and don't want to hurt the nozzle, drill a hole first rather than gouge a slot in it.

What a pro! Working with a cutter wearing a hawaishirt.

Same result, most farm kids figure this out by 12 yrs old ! Glad I had an adult make this video

Professional welding shirt... where can I get one?

[chrismartinez]

used this on ship for emergency to basically remove a weld or door if necessary

[jimmyohdez]

make sure to angle it towards your co worker

Le découpage au plasma avec air comprimé et bien rapide pour la tôle pas trop épaisse sinon la coupe est rarement à 90°, il existe des placements ou la torche touche la pièce et d'autres ou la torche ne touche pas ça dépend tout de la configuration de l'appareil mais il est préférable de faire un trou à la perceuse et de partir depuis la, pour les alliages chrome/ nickel acier inoxydable il existe des plasma avec gaz de protection pour la coupe pas que ça ne roche pas, comme l'envers d'une soudure qui n'est pas protégé!

I always dril a pilot hole, only needs to be 1/8-5/32"

Plasma cutter consumables are cheap, messing a job can be expensive. I prefer to cut it perpendicular

[ImAnAmericanMan]

I usually drill a hole and then aim for the opening.

[firefly]

Is the shirt work shirt? 😮😮I want one for sure, pretty please

[BenjaminMilesPerry]

Come in on the drop, it's waste anyway! Pre drill ( on a heavier T), or coverup and let the CONSUMABLES do what they are for. Besides,
auto mated machines go strait in. I think they are programmed to puff a few extra pds for the initial arc tho?

Your first problem is you picked up a plasma instead of a cutting Torch.
