BATTERY CHARGING OUTPUT and BATTERY
EXPLOSION can injure.
Battery charging not present on all models.
Always wear a face shield, rubber gloves, and protective
clothing when working on a battery.
Stop engine before disconnecting or connecting battery cables,
battery charging cables (if applicable), or servicing battery.
Do not allow tools to cause sparks when working on a battery.
Do not use welder to charge batteries or jump start vehicles un-
less it has a battery charging feature designed for this purpose.
Observe correct polarity (+ and − ) on batteries.
Disconnect negative ( − ) cable first and connect it last.
Keep sparks, flames, cigarettes, and other ignition sources
away from batteries. Batteries produce explosive gases during
normal operation and when being charged.
Follow battery manufacturer’s instructions when working on or
near a battery.
Have only qualified persons do battery charging work.
If battery is being removed from a vehicle for charging, discon-
nect negative ( − ) cable first and connect it last. To prevent an arc,
make sure all accessories are off.
Charge lead-acid batteries only. Do not use battery charger to
supply power to an extra-low-voltage electrical system or to
charge dry cell batteries.
Do not charge a frozen battery.
Do not use damaged charging cables.
Do not charge batteries in a closed area or where ventilation is
restricted.
Do not charge a battery that has loose terminals or one showing
damage such as a cracked case or cover.
Before charging battery, select correct charger voltage to match
battery voltage.
Set battery charging controls to the Off position before connect-
ing to battery. Do not allow battery charging clips to touch each
other.
Keep charging cables away from vehicle hood, door, or moving
parts.
WELDING WIRE can injure.
Do not press gun trigger until instructed to do
so.
Do not point gun toward any part of the body,
other people, or any metal when threading
welding wire.
OVERUSE can cause OVERHEATING.
Allow cooling period; follow rated duty cycle.
Reduce current or reduce duty cycle before
starting to weld again.
Do not block or filter airflow to unit.
STATIC (ESD) can damage PC boards.
Put on grounded wrist strap BEFORE handling
boards or parts.
Use proper static-proof bags and boxes to
store, move, or ship PC boards.
TILTING OF TRAILER can injure.
Use tongue jack or blocks to support weight.
Properly install welding generator onto trailer
according to instructions supplied with trailer.
READ INSTRUCTIONS.
Read and follow all labels and the Owner’s
Manual carefully before installing, operating, or
servicing unit. Read the safety information at
the beginning of the manual and in each
section.
Use only genuine replacement parts from the manufacturer.
Perform maintenance and service according to the Owner’s
Manuals, industry standards, and national, state, and local
codes.
H.F. RADIATION can cause interference.
High-frequency (H.F.) can interfere with radio
navigation, safety services, computers, and
communications equipment.
Have only qualified persons familiar with
electronic equipment perform this installation.
The user is responsible for having a qualified electrician
promptly correct any interference problem resulting from the
installation.
If notified by the FCC about interference, stop using the
equipment at once.
Have the installation regularly checked and maintained.
Keep high-frequency source doors and panels tightly shut, keep
spark gaps at correct setting, and use grounding and shielding to
minimize the possibility of interference.
ARC WELDING can cause interference.
Electromagnetic energy can interfere with
sensitive electronic equipment such as micro-
processors, computers, and computer-driven
equipment such as robots.
Be sure all equipment in the welding area is
electromagnetically compatible.
To reduce possible interference, keep weld cables as short as
possible, close together, and down low, such as on the floor.
Locate welding operation 100 meters from any sensitive elec-
tronic equipment.
Be sure this welding machine is installed and grounded
according to this manual.
If interference still occurs, the user must take extra measures
such as moving the welding machine, using shielded cables,
using line filters, or shielding the work area.
