[bobcj360]

hi i am new to welding.have purchased a kennedy E M W 150 T .
it is new secondhand [freind of mine bought it never used]
bought it mainly to learn welding .with a view to altering my
bike trailer when i am capable.
first i could use a manual
sec which gas to use
my trailer is made of mild steel about 3mm angle and cequerplate
will co2 be adequate. or do i need ar/co2

thanks bob

Hi Bob, I moved your post to a new one rather than piggyback an existing one, it's more likely to get seen .
Not sure where you'd find a manual for that machine unless there's another member on here with one, try a forum search and see what comes up.
Co2 is ok but doesn't give as nice a weld as ar/co2 mix, it can be a bit spattery.

Hi Bob, welcome to the Forum.

Just to clear up a point, is the chequerplate steel or aluminium?

hi
sorry its mild steel spotwelded between two lenghts of 2inch angle to form the runners. whitch in turn are welded to the 2inch square chassis.
i intend to use my grinder fitted with a slitting disc to remove them
and re weld farther apart
