hey guys , i just got an airco heliwelder 300 amperes machine, cam with tig torch , cables , water tank .. looks to be in good condition ,guy i bought it from had it working , and he set up it for 220v for me , i pluged it in and fan turned on etc , i turned the thumb wheel and it ran for about 10 seconds and tripped my breaker , my breaker is 30 amps , so i guess i need to upgrade that to i assume 50 amps , i have 200 amp service in my shop

now my big question , this has a few dials and things and i dont wanna mess it up , so if i take some up close pics of it would you guys help give me a base line as to where to start with chromemoly wleding and then aluminum welding ?

i wont be able to get pics to you guys for a few days .. but if anyone has maybe some info that would be great also...

thanks ted

My guess would be more in the range of 100 amp breaker.

ok here are some pics of the machine , it works pretty good .. after using that darn buzz box add on and scratch starting this is pretty cool , and easy to use

the main question i have is when doing aluminum there is dcsp dcrp and ac ...which setting do i use for doing chrome moly , i used it on dcsp and it worked good , i want to try it on aluminum , which setting ?

also the high freq ., it has start off and continus... where should i leave that and what is the differnece on the 3 settings

on the 2 knobs on top it has start current and weld current , what does this mean ? and also the 2 knobs how do they work together

i think thats all the questions i have right now , i hope you guys can give me some input on this machine , and also the pateince for dealing with me as im new to the bigger machines thanks ted
