1. Precautions for Handling

・ To ensure safety, installation, maintenance, and repair of this device must be made by

qualified personnel or personnel familiar with the device.

・ To ensure safety, the personnel who operates this device must understand this

operation manual and acquire knowledge and skills of safe handling.

・ After reading this operation manual, save it in a proper place where you can easily

access and read it again as needed.

・ If there is anything unclear, contact us.

: Denotes operations and practices that may imminently result in

serious injury or loss of life if not correctly followed.

: Denotes operations and practices that may result in serious injury or

loss of life if not correctly followed.

: Denotes operations and practices that may result in personal injury or

damage to the equipment if not correctly followed

・ This device was designed with safety in mind, but be sure to follow the precautions in

this operation manual when using it. If not followed, serious accident causing loss of

life or serious injury may result.

・ Keep any unauthorized people out of the device and welding site.

・ A person who uses a pacemaker must not approach the welding machine or walk

around the welding site while the welding machine is in operation, without being

permitted by his/her doctor. The welding machine generates a magnetic field and has

effects on the operation of the pacemaker while it is turned on.

・ Touching to the charged portion causes fatal electric shock or burns. With power

output from the welder, electrode, collet body, collet, and cap are electrically charged.

・ To prevent case and workpiece or jig electrically connected to workpiece, etc. from

being electrically charged, perform grounding work.

・ For installation and maintenance check, be sure to turn off the input power with switch

in switch box.

・ Be sure to tighten and isolate the cable connection.

・ Maintain and inspect the device periodically, and repair any damage nearby before

starting operation.

・ Do not use cables of insufficient current capacities, damaged, or exposed conductor.

・ Securely connect the EARTH cable as close to a workpiece to be welded as possible.

・ Do not use torn or wet gloves. Always use dry insulating gloves.

・ When not in use, turn off the power to all equipments.

1. Precautions for Handling

1-2

・ Arc light source can irritate the eyes or burn the skin.

・ Spatter and slag can damage the eyes or burn the skin.

・ Noises can damage hearing.

・ When monitoring the welding site or welding, wear an eye protector with sufficient

scale or protective masks for welding.

・ To protect eyes from spatter and slag, wear protective glasses.

・ Put up protective curtains around the welding site to protect people’s eyes from arc

light source.

・ When welding, put on protective gear such as leather protective gloves for welding,

long-sleeve jacket, leg cover, leather apron, etc.

・ For loud noises, use ear protectors.

・ Inhalation of gas or fume produced during welding can cause health damage.

・ Welding in narrow spaces can cause suffocation from oxygen deficiency.

・ In places set by regulations (Ordinance on the Prevention of Oxygen Deficiency, etc.),

provide adequate ventilation or use a breathing apparatus, etc. to avoid gas poisoning

or suffocation.

・ For welding in narrow spaces, be sure to provide adequate ventilation or use a

breathing apparatus, etc. in addition to performing a work under the supervision of

trained observer.

・ Do not perform welding near degreasing, cleaning, and spray works. Performing

welding near such works can produce harmful gas.

・ Shielded nozzle and electrode are very hot just after welding. Touching them

carelessly may result in burns.

・ Do not touch shielded nozzle and electrode by hand just after completion of welding.

2. Installation

Note 1: Let the electrode diameter φ

D mm. The dimension above is reference.

Check the proper value.

Note 2: The clearance between electrode and workpiece changes depending on

weldment. The dimension above is reference. Check the proper value.

Note 3: The nozzle ring is attached to TA-150AC/300WC.

Install the nozzle ring to the torch nozzle, and connect the cable terminal

connected to the nozzle ring to the PE terminal of MAWA-050A/300B. This

may increase the probability of LOST.

* Since LOST is caused by multiple factors, it is not totally eliminated.
