While I was tig welding aluminum my welder went to full amps and blew up the part I was welding. After trying other things I discovered it will weld on the panel setting but as soon as you push the remote pedal it goes to the max amp setting , there is no control with the pedal. I sent the remote pedal to be checked and it is operating properly. My welder serial number is LG 030068L if this helps. Thanks for any assistance .. John
