non hf plasma cutter

[asuratman]

I have problem with interference on my cnc plasma due to my plasma cutter Cut 40. Then I plan to purchase non hf plasma cutter. there are 2 types that I can choose to purchase. cheaper one is non hf plasma cutter cut 50 with P80 cutting torch not a blow back type. Another one plasma cutter non hf cut 55 with blow back plasma torch.

Do you think cheaper one with P80 non blowback torch is OK, no interference ? Or I should buy plasma cutter non hf with a blowback torch since a must for non hf ? Thanks.

I would go with the blow back plasma setup.

thanks for recommendation, I think you are right, a blowback torch is a must for non hf ...

How do they fire a p80 torch without HF ?
