Precautions

Users of ESAB welding and cutting equipment have

ultimate responsibility for ensuring that anyone

who works on or near the equipment observes all

relevant safety precautions. Safety precautions must

meet requirements that apply to this type of welding

or cutting equipment.

All work must be carried out by trained personnel

well acquainted with operation of welding or cutting

equipment. Incorrect operation of equipment may

lead to hazardous situations which can result in

injury to the operator and damage to equipment.

The following recommendations should be observed

in addition to standard regulations that apply to the

workplace.

1. Anyone who uses welding or cutting

equipment must be familiar with:

…Proper operation.

…Location of emergency stops.

…Designed function.

…Relevant safety precautions.

…Welding and/or cutting.

2. Operators must ensure that:

…No unauthorized person within the working

area of equipment when it is started up.

3. The workplace must be:

…Suitable and

…Free from drafts.

4. Personal safety equipment:

…Always wear recommended personal safety

equipment, such as safety glasses, ame proof

clothing, and safety gloves.

…Do not wear loose tting items, such as

scarves, bracelets, rings, etc., which could become

trapped or cause burns.

Safety

6

B4-350 QuattroJet Assembly

5. General precautions:

…Make sure return cable is connected securely.

…Work performed on high voltage equipment

may only be carried out by a qualied

electrician.

…Appropriate re extinguishing equipment

must be clearly marked and close at hand.

…Lubrication and maintenance must not be

carried out on equipment during operation.

The IP code indicates the enclosure class, i.e. the

degree of protection against penetration by solid

objects or water. Protection is provided against

touch with a nger, penetration of solid objects

greater than 12mm and against spraying water up to

60 degrees from vertical. Equipment marked IP23S

may be stored, but is not intended to be used out-

side during precipitation unless sheltered.

Enclosure Class

Maximum

Tilt Allowed

15°

If equipment is placed on a surface that slopes

more than 15°, toppling over may occur.

Personal injury and/or signiﬁcant damage to

equipment is possible.

CAUTION

WELDING AND CUTTING CAN CAUSE

INJURY TO YOURSELF AND OTHERS.

TAKE PRECAUTIONS WHEN WELDING OR

CUTTING. ASK FOR YOUR EMPLOYER’S

SAFETY PRACTICES WHICH SHOULD BE

BASED ON MANUFACTURERS’ HAZARD

DATA.

WARNING

7

B4-350 QuattroJet Assembly

FUMES AND GASES - Can be dangerous to health.

• Keep your head out of the fumes.

• Use ventilation, extraction at the cut, or both, to

take fumes and gases away from your breathing

zone and the general area.

FIRE HAZARD - Sparks (spatter) can cause re. Make

sure that there are no ammable materials nearby.

MALFUNCTION - Call for expert assistance in the

event of malfunction.

Introduction

The B4-350 lift assembly provides vertical motion

for the torch, using a typical motor, screw, and slide

conguration. The motor turns an enclosed spindle

screw, which in turn raises/lowers the lifting plate

along linear rails. Directional commands given from

CNC determines direction of lift travel. Fixed limit

switches are included to prevent upper and lower

over travel.

The lift assembly also contains components

necessary to control height over work surfaces.

Maintenance

Preventative Maintenance

Schedule

Time periods suggested below are based on average

plasma station usage. If station is employed in

a heavy usage cycle, used outdoors, or used on

a multi-torch cutting machine, suggested time

intervals should be shortened. Regularly scheduled

maintenance will signicantly increase the life and

performance of your equipment.

Daily

• Wipe dust and fume buildup from lift assembly

and components.

• Check for worn or damaged cables on all lift

subassemblies.

• Ensure all mechanical fasteners and electrical

connections are correct; no stripping of

hardware, connections are tight, exposed wires,

etc.

• Check that lift travel limit switches are

functioning correctly.

• Use your CNC’s station travel buttons to ensure

lift assembly has proper, smooth movement.

Read all instruction manual’s safety

and maintenance procedures

before beginning any preventative

maintenance!

CAUTION

16

B4-350 QuattroJet Assembly

Weekly

• Check alignment of lift assembly.

Monthly

NOTICE

Many replacement parts subject to wear

or used in preventative maintenance

schedules are available directly through

ESAB Cutting Systems.

See “Consumables and Spare Parts”

section in Replacement Parts portion of

this manual before ordering.

• Clean and lubricate slide assembly (see

procedure on page 18).

Semi-Annually

• Repeat all previous maintenance procedures.

• Consider calling your ESAB Service

Representative to schedule an semi-annual

station inspection.

B4-350 QuattroJet Assembly

Maintenance Procedures

The following section contains maintenance

procedures for the lift assembly and components.

This section will provide some basic troubleshooting

methods to return your station to correct operation.

Only qualied maintenance personnel should utilize

these procedures.

18

B4-350 QuattroJet Assembly

B4-350 Lift

In order for B4 slide assemblies to perform at

optimum levels, it will need to be inspected, cleaned

and lubricated on a weekly basis. The following

procedure will detail steps necessary to correctly

clean and lubricate your slide assembly:

1. Remove (3) cap screws attaching front cover.

2. Run lift to lower limit and wipe ball screw with

a clean, dry cloth. Apply lithium based NGLI 2

grease or softer grease directly to screw.

Introduction

The B4-350 heavy duty vertical lift employs an

enclosed motor that turns a ball screw. This is made

possible by using a pair linear bearing blocks and a

drive belt, which lowers or raises the lifter assembly

along linear rails. Direction depends on commands

received form the CNC. The illustration at left is the

B4 lift with some parts hidden for clarity. The three

grease ttings can be accessed without removing lift

covers.

Do not use solvents or solvent-based

lubricant to clean ball screw; this can

remove lubricant from sealed linear

bearing blocks.

CAUTION

3. Run lift to upper limit.

4. Apply same grease to three zerk ttings; apply

0.1 ounce (3cc) or half pump of a grease gun to

each tting.

NOTICE

Lift covers do not need to be removed to

access grease ﬁttings.

See illustration above for ﬁtting locations.

5. Reinstall front cover to lift assembly.
