I know. I know. That's not really a thing. Still I was welding up some
T-handles on thread rod for some tools yesterday. I noticed that for just a
fraction of a second at the beginning of the first weld on a part the weld
would be unstable and throw a little spatter. Then it would stabilize and
weld perfectly. All I can attribute it to is that it took a tiny fraction
of a second for gas to reach the nozzle. Still if the gas solenoid was
triggered half a second before the wire was electrified I can't help but
think the start would be better. When I shut the welder off I happened to
notice my CFH gage was showing a little under 20, and the welder recommends
30 for everything on the flip chart. The other day welding hinges on some
thin wall rectangular tube 20 seemed to be fine. Maybe it was just the
shape of the t-bolt? Maybe the 30CFH setting hits the nozzle quicker? I
have the regulator style flow gages.
P.S. Referring back to my issues with this welder and the bad gas
diffuses... I use MIG welding as the fast fall back tool for a lot of
things I'd often find other means for in the past. Even my crappy welds
look better. I haven't used my little flux core only machine since,
although I still would outdoors.
What gases are you using? As a side note..yeah..use whatever pressure
is recommended by your welders manufacture. I have a little guard
system...just 3 12x12 panes of lucite formed into 2/3rds of a box,
that I tend to mig weld inside of. My welding shop is a covered 16x16'
area..with sheet steel fenceing on 2 sides..so wind isnt a BIG
problem..but it is a minor problem. Blows the shielding gases away.
The little 3 sided gizmo helps keep gas where it belongs.
