[SEL] A Welding Question - CooperTB (Stover CT2)

[sutter]

Thanks for your advice Tony. I would much prefer to have the crack
welded without heating the block red hot - it would probably never be
the same. I will contact some local welders and see what they say.

Rod,
I just got done welding up the wet head on my 2 
1/4 hp Economy.  I used my stick welder with 
nickel rod.  I ground the welding surface to a V 
and welded about 3/4" at a time letting it cool 
for 30-40 minutes between welds.  No preheating at all.

My arc welder is AC/DC, so I used DC+ and it 
turned out to be a VERY nice weld.  I ground it 
down with my angle grinder and once I paint it, 
nobody will know it's even there.

The most important thing is to get the surface 
CLEAN CLEAN CLEAN!  Otherwise it will be a very 
porous weld.  Brake cleaner and a wire brush work 
very well.  Just make sure the brake cleaner is 
fully evaporated before you start to weld!
