Hi, I just got a Super Kempak 150 Tig and I have some problems using it. Well really only one issue, I cant get the TIG to arc with the metal (if thats the correct word choice). This machine is quite old and I have only used the newer Kemppi machines. I have used the super kempak for Arc welding that works fine. I have placed the switch to Tig and the pedal control switch is off. However I can not get the arc to start when I try to weld the metal, I have tried to scratch start it als doesn't work. When I press the button on the torch I hear the relay click and the gas starts flowing, but no arc. Any help much apperciated! -Robert Ps if anyone has a manual that would help alot too.
