I bought a used xmt 300 cc/cv and took it to a local welding shop to have looked over and checked out. They gave it back to me and said everthing was good to go. I plug in the welder tonight for the first time and hooked up my tig tourch, ground cable and foot pedal. I fliped the switch and it turns on and runs but when i try to start welding i get nuthing. It dosn't seem like it is tring to start an arc. I pulled the top cover off and see nuthing out of the ordaniry. Where would be the best place to start looking for a problem.
thanks joe
