Feeds wire at 78 in. Per minute and has infinitely adjustable wire speed and heat settings. This welder does not use tapped controls that are found in cheaper machines! This model uses an advanced compact IGBT inverter design with automatic overheat and over current welding protection.
The model 155 incorporates 2T/4T modes. 4T is useful if you have a long weld to do, as it saves you having to hold the trigger down the whole time. Great feature for out of position welding.
