You make it sound like a bad thing haha.GTAW you need 500+ amps with 100% HE, water cooled torch and hope to hang in their jamming filler around with a hot torch. No thanks.
I’ve welded near 400 amps TIG before on my machine. It’s quite fun. But you need a torch that can handle it and a big water cooler. My water cooler can handle 600amps so my torch never got hot with its duty cycle being 350.
Where many go wrong with high amperage welding is crappy PPE. They don’t have the right gloves and arm protection.
