I was reading what the machine comes with and noticed that the machine comes with a 150A torch. Thats fine but this is a 200A machine. Does this mean i can only weld up to 150A with this setup?
no it dose not. the torch is rated at 100% duty cycle at 150amps the torch can go over 150amps just for shorter periods of time just like the welder has a duty cycle so too dose the torch. most all torches are rated at 100% duty cycle. where as most welders are not named for there 100% duty cycle.
the syncrowave is rated at
150 A at 26 V, 40% Duty Cycle
so as you can see the syncrowave is rated lower than the 150amp torch they ship with it. you will be fine to use the torch for the full range of the syncrowave 200. the #17 torch is very common and is on most all the 180-225 amp welders. i have one on my TA-185. its a nice size and feel. if later you chose to get a smaller one for tight spots or just for low amp use thats possible as well as adding a cooler. torches come in all sizes and styles. the #17 is a good mid range torch. after you have been TIGing for a wile if you feel the need or want you can easily change it out.
