Machine Installation
1.1 Location
Place the welder where clean cooling air can freely
circulate in through the front louvers and out through the
rear louvers. Dirt, dust or any foreign material that can be
drawn into the welder should be kept at a minimum. Failure
to observe these precautions can result in excessive
operating temperatures and nuisance thermostat trips.
