The risk of VAP is highest early in thecourse of hospital stay, and is estimated to be 3%/day duringthe ï¬rst 5 days of ventilation, 2%/day during Days 5 to 10 ofventilation, and 1%/day after this (17).
there is a difference. There are other here who could elaborate further but MIG stands for metal inert gas. This is Argon or c02. Inert meaning the gas has no affect on the weld except to shield it from oxidation, from the atmosphere. MAG is metal active gas.
in mig welding the voltage is what is controlled and adjusted when comparing mig welding to arc or tig welding mig welding machines use voltage settings to set the machine tig and arc welding machines use amperage to set the machine or a constant amperage power supply
