Hi Guys. I`m new to tig welding and have just bought a Matweld 160 DC inverter welder. It works very well as a "stick" welder and now I would like to try TIG welding. I have got a tig torch,1/16" tungsten electrodes,THERMAMAX Flow Meter and a large pure argon bottle. I managed to source 1 KG of Mig wire (1/16" dia.) to try it on 1" Sq. X 1/16" wall thickness square mild steel tubing. My question is - What amperage should I start with and also the flow meter output flow? I`m aware that the TIG torch is connected to the (-) connection and the earth clamp to the (+) connection. I assume that the most difficult part will be to start the arc,as this is not a proper tig welding machine? I`ve read about "scratch starting",to start the arc. Any advice would be very much appreciated.
