2 SAFETY

Users of ESAB welding equipment have the ultimate responsibility for ensuring that anyone who

works on or near the equipment observes all the relevant safety precautions. Safety precautions

must meet the requirements that apply to this type of welding equipment. The following recommen-

dations should be observed in addition to the standard regulations that apply to the workplace.

All work must be carried out by trained personnel well–acquainted with the operation of the welding

equipment. Incorrect operation of the equipment may lead to hazardous situations which can result

in injury to the operator and damage to the equipment.

1. Anyone who uses the welding equipment must be familiar with:

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.

SLubrication and maintenance must not be carried out on the equipment during operation.

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

Application classification

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

electrical hazard.

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.
