When Welding this machine is smooth. Portable not too Big. Nice Size Machine i mounted mine on a truck. Also loved all the Power Outlets on it to run other equipment, Grinders etc. Very Easy to set up. Good for a variety of projects. The Place where I used to work has one of these and we used it hard and it came back for more. Of course we kept it well maintained such as changing the oil regularly and bringing in out of the elements. Would recommend this machine because it is reliable. The Machine always started right up without any problems and was ready to go. We Loved the Machine so much we purchased a second one. Very productive Machine.
