Atwood Retaining Ring Swivel Jacks.
Atwood mounting bracket is designed to ensure proper engagement of
the locking pin during use.
Atwood mounting bracket and retaining ring is designed as a system
with Atwood jacks to ensure proper snap ring engagement, retention
and lock pin function.
HANDLE MAY INJURE OR DAMAGE PROPERTY
, jack handle must clear all obstructions when in use.
Install jacks in accordance with provided instructions.
Adequate ventilation must be provided when welding.
PREPARE THE METAL
Metal must be completely clean and free from rust or paint before welding. It is
difficult to arc against a dirty surface, but any contaminants will find their way
into the weld and reduce its strength. Light use of an angle grinder or flap
wheel will quickly remove surface rust and paint. For more inaccessible areas
an air grinder or dremmel can b e effective.
- 5/32˝ fillet weld minimum.
- Use A.W.S. ER 70S-3 or 6 wire or equivalent with a
diameter of .035 - .045. The recommended shielding gas mixture is
75% - 95% Argon & 25% - 5% CO
- Use E6011 A.W.S. welding rod or equivalent with a
diameter as follows: 1/8" electrode set power between 115-130 Amps
DC or 5/32" electrode set power between 140-160 Amps DC.
