Sits operation
Slocation of emergency stops
Sits function
Srelevant safety precautions
Swelding
2. The operator must ensure that:
Sno unauthorised person is stationed within the working area of the equipment when it is
started up.
Sno–one is unprotected when the arc is struck
3. The workplace must:
Sbe suitable for the purpose
Sbe free from draughts
4. Personal safety equipment
SAlways wear recommended personal safety equipment, such as safety glasses, flame–proof
clothing, safety gloves.
SDo not wear loose–fitting items, such as scarves, bracelets, rings, etc., which could become
trapped or cause burns.
5. General precautions
SMake sure the return cable is connected securely.
SWork on high voltage equipment may only be carried out by a qualified electrician.
SAppropriate fire extinquishing equipment must be clearly marked and close at hand.

WARNING
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU-
TIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ HAZARD DATA.
ELECTRIC SHOCK – Can kill
SInstall and earth the welding unit in accordance with applicable standards.
SDo not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
SInsulate yourself from earth and the workpiece.
SEnsure your working stance is safe.
FUMES AND GASES – Can be dangerous to health
SKeep your head out of the fumes.
SUse ventilation, extraction at the arc, or both, to take fumes and gases away from your breathing zone
and the general area.
ARC RAYS – Can injure eyes and burn skin.
SProtect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
SProtect bystanders with suitable screens or curtains.
FIRE HAZARD
SSparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE – Excessive noise can damage hearing
SProtect your ears. Use earmuffs or other hearing protection.
SWarn bystanders of the risk.
MALFUNCTION – Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
WARNING!
Read and understand the instruction manual
before installing or operating.
Do not use the power source for thawing frozen pipes.
WARNING!
This product is solely intended for arc welding.

3 INTRODUCTION
The ESABMig 325 are step switched power sources designed for MIG/MAG–welding
together with wire feed units ESABFeed 30 and the most of ESAB wire feeders.
The power units are fan–cooled and equipped with thermal overload protection.
The machines can be fitted with an instrument for display of current and voltage. It
incorporates a hold function and can be calibrated.
ESAB’s accessories for the product can be found on page 141.
3.1 Equipment
The power source is supplied with:
SReturn cable 5m with return clamp
SShelf for gas cylinder
SGuide pin for wire feed unit

Duty cycle
The duty cycle refers to the time as a percentage of a ten–minute period that you can weld at a cer-
tain load without overloading.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked IP23 is designed for indoor and outdoor use.
Application class
The symbol indicates that the power source is designed for use in areas with increased

6.2 Function explanation
6.2.1 Overheating protection
A thermal overload cutout protects against overheating. The cutout resets automatically
when the unit has cooled.
6.2.2 Inductance connection
Higher inductance produces a more flowing weld and fewer spatters. Lower inductance
produces a harsher sound and a stable, concentrated arc.
