Answer :
The air pressure supplied to the torch is d) 120 and 200 psi.
In welding and cutting operations, the torch is typically used with gases such as oxygen and acetylene or propane. The pressure requirements for these gases can be relatively high to ensure proper operation and flame characteristics.
Torch manufacturers often recommend specific pressure ranges for optimal performance. According to general welding practices, the safe and effective range for air supply pressure to the torch falls within 120 to 200 psi. Always refer to the torch manufacturer's manual for the exact pressure settings specific to the equipment being used.
