## Step 1The question is about the setup of GTAW (Gas Tungsten Arc Welding) equipment. The focus is on the reason why the shielding gas supply must be located reasonably close to the welding site.## Step 2The options provided are:a. limited length of GTAW torch cablesb. risk of acetylene dispersion at the work sitec. weight and immobility of the gas cylindersd. need to refuel the torch frequently## Step 3The correct answer is option a, which states that the shielding gas supply must be located reasonably close to the welding site because of the limited length of GTAW torch cables. This is because the shielding gas is crucial for protecting the weld from atmospheric contamination, and having the gas supply close to the welding site ensures a stable and consistent flow of gas.
