Hello I just received my power pro 205 and I cannot seem to get it to weld. The machine powers up fine. For some reason the max amps in tig on the display is 140-141. When I hit the button on the tig torch I can hear the high frequency and see the high frequency arc to the metal but it wont start an arc and I do not hear any gas coming out. The gas valve was open but I don't hear it coming out as the high frequency kicks on but an arc wont start. The ground is connected. Also in stick mode it will not strike and arc either. Same thing, hooked up the ground and put in an electrode and tried to strike an arc but nothing. Am I retarded or am I missing something here?
