185 AMP PULSE MIG WELDER
MIG185i
The MIG185i Pulse is a 230VAC single-phase synergic inverter power source for MIG welding. This
versatile power source is suitable for various applications from general repairs to speci c material
types used in the body shop industry. Welds a variety of material types and thicknesses such as
steel, stainless-steel, aluminum, high strength and boron steels. Preset synergic curves automati-
cally provide proper settings for individual situations and reduce set up times.

SAFETY INFORMATION
MUST READ INSTRUCTIONS BEFORE USE
Read, understand and follow all safety messag-
es and instructions in this manual. Safety mes-
sages in this section of the manual contain a sig-
nal word with a three-part message and, in some
instances, an icon.
The signal word indicates the level of the hazard in a situ-
ation.
Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury to the opera-
tor or bystanders.
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury to the op-
erator or bystanders.
Indicates a potentially hazardous situation which, if not
avoided, may result in moderate or minor injury to the
operator or bystanders.
IMPORTANT
Indicates a situation which, if not avoided, may result in
damage to the welding equipment.
Safety messages in this section contain three different
type styles.
• Normal type states the hazard.
• Bold type states how to avoid the hazard.
• Italic type states the possible consequences of not
avoiding the hazard.
An icon, when present, gives a graphical description of
the potential hazard.
Arc Welding
Electric welding or plasma cutting causes ultra-
violet rays and weld spatter.
Bystanders will be exposed to ultraviolet rays
and weld spatter.
Wear welding helmet with appropriate shade
lens while using electric welders or plasma
cutters.
Do not allow bystanders while welding or
cutting.
Wear safety shield and protective clothing.
Ultraviolet rays will burn eyes; weld spatter can
cause injury.
Welding produces heat, sparks, hazard of elec-
tric shock and/or hazardous vapors
Wear appropriate gloves, helmets or goggles
and other protective clothing.
Follow all instructions and safe practices
while welding or cutting.
Keep bystanders away from immediate area.
Byproducts of welding can cause burns or other
bodily injury.
Risk of Electrical Shock
Electrical shock can result when contacting live
electrode or internal components
Electrical shock can result from absence of
grounding lug.
Welding machine must be connected to
power source in accordance with applicable
electrical codes.
Do not touch electrode or internal compo-
nents without protection.
Disconnect power before servicing.
Do not remove the grounding lug in any elec-
trical plug.
Electrical shock can cause injury.

4
Risk of Explosion
Welding causes sparks that can cause explosion.
Use caution and proper procedures when
welding.
Avoid sparks if gasoline vapor and other fuels
are present.
Electrical shock, ames and explosion can cause
serious injury.
Electrical and Magnetic Fields
Welding may cause localized electrical and mag-
netic elds araund cables and power sources.
The magnetic elds created by high currents
may affect the operation of medical equipment.
Route the electrode and work cables together.
Do not place your body between the elec-
trode/torch and work cables.
Never coil the electrode/torch lead around
your body.
Do not work next to welding/cutting power
source.
Electrical shock and Magnetic elds can cause
injury.
H.F RADIATION can cause interference
• High frequency (H.F.) can interfere with
radio navigation, safety services, comput-
ers, and communications equipment.
• Have only qualied persons familiar with
electronic equipment perform this instal-
lation.
• The user is responsible for having a qualied electri-
cian promptly correct any interference problem resulting
from the installation.
• If notied 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 ground-
ing and shielding to minimize the possibility of interference.
Disposal of Equipment
IMPORTANT
Disposal of electrical equipment can be hazard-
ous to the environment.
Contact local regulations prior to disposal.
Improper disposal can cause an environmental
hazard.
FUMES AND GASES can be dangerous to your
health.
ITEMS REQUIRED FOR MIG WELDING WHICH ARE
NOT PROVIDED WITH THE MIG185i.
1. Full cover welding helmet with proper colored lens
(shade 9 to 11, depending on operator's preference).
2. Proper shielding gas and cylinder.
3. Leather welding gloves.
4. 230 volt single phase 30 Amp AC power.
5. Other personal protective equipment, which may vary
to match the welding being performed.

GENERAL DESCRIPTIONS
This welding machine is a power source developed with
inverter technology, suitable for MIG welding.
This welding machine must not be used to defrost pipes.
EXPLANATION OF TECHNICAL SPECIFICATIONS
LISTED ON THE MACHINE PLATE
This machine is manufactured according to the following
international standards:
IEC 60974-1 / IEC 60974-10 (CL. A) / IEC 61000-3-11 /
IEC 61000-3-12.

U0. Secondary open-circuit voltage.
X. Duty cycle percentage.
The duty cycle expresses the percentage of
10 minutes during which the welding ma-
chine may run at a certain current without
overheating.

I2 current and U2 voltage.
I1 eff This is the maximum value of the actual cur-
rent absorbed, considering the duty cycle.
This value usually corresponds to the capac-
ity of the fuse (delayed type) to be used as a
protection for the equipment.
IP23S Protection rating for the housing. Grade 3
as the second digit means that this machine
may be stored, but it is not suitable for use
outdoors in the rain, unless it is protected.
S Suitable for use in high-risk environments.
NOTE:
The equipment has also been designed for use in environ-
ments with a pollution rating of 3. (See IEC 60664).
