So is it worth it? The Trek 180 is easy to use, being a MIG, and makes enough weld for your average trail repair on a full charge. It can also be used at home just like a standard 110 MIG welder when plugged into an outlet. In fact with its 180 amp rating while plugged in to 110 volts, it is actually a better welder than most 110 welders and on par with some 220V welders. So yes, we think it's worth it.
