Trailer
If the user adapts a trailer, he must assume responsi-
bility that the method of attachment and usage does
not result in a safety hazard nor damage the welding
equipment. Some of the factors to be considered are
as follows:
1. Design capacity of trailer vs. weight of equipment
and likely additional attachments.
2. Proper support of, and attachment to, the base of
the welding equipment so there will be no undue
stress to the framework.
3. Proper placement of the equipment on the trailer to
ensure stability side to side and front to back when
being moved and when standing by itself while
being operated or serviced.
4. Typical conditions of use, i.e., travel speed, rough-
ness of surface on which the trailer will be operat-
ed; environmental conditions, likely maintenance.
5. Conformance with federal, state and local laws.

Improperly mounted concentrated loads may
cause unstable vehicle handling and tires or other
components to fail.
• Only transport this Equipment on serviceable
vehicles which are rated and designed for such
loads.
• Distribute, balance and secure loads so vehicle
is stable under conditions of use.
• Do not exceed maximum rated loads for compo-
nents such as suspension, axles and tires.
• Mount equipment base to metal bed or frame of
vehicle.
• Follow vehicle manufacturer’s instructions.

Polarity Control and Cable Sizes
With the engine off, route the electrode and work
cables and connect to the studs located below the fuel
tank mounting rail. (See size recommendations
below.) For positive polarity, connect the electrode
cable to the terminal marked “+” . For Negative polari-
ty, connect the electrode cable to the “-” stud. These
connections should be checked periodically and tight-
ened if necessary.
When welding at a considerable distance from the
welder, be sure you use ample size welding cables.
