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.

・ 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.

(1) Replacing the Electrode
The procedures of replacing the electrode are as follow:
①Turn the big knob at the insert unit counterclockwise to release the insert unit.
②Lift the released insert unit to remove the insert unit.
③Turn the small knob at the torch cap counterclockwise with holding the big knob
at the insert unit to remove the torch cap from the insert unit.
④By removing the torch cap, you can disassemble the collet and the electrode
and replace the electrode.

⑤Prepare an electrode with the polished tip.
Combine the electrode and collet so that the thinner side of the collect comes to
the electrode tip side and insert the electrode into the torch cap.
⑥Combine the electrode, collet and torch cap to insert them into the torch head.
⑦Turn the torch cap knob clockwise and press the collet with the torch cap and
the collet body to fix the electrode.
When the electrode extension is 23 mm at this time, it becomes approx. 3 mm
from the nozzle in the final form.
⑧If the collet body and the torch head are not firmly tightened, the collet body
turns when the collet is pressed and a clearance between the collet body and
the torch head is generated. It results in that the electrode cannot be fixed
firmly. In this case, firmly tighten the collet body and the torch head by hand
after turning the torch cap knob counterclockwise not to generate a clearance.
After confirming that there is no clearance, fix the electrode as shown in ⑦.
⑨Install the insert unit fixing the electrode in the torch body.
The insert unit is fixed by firmly tightening the insert unit knob clockwise. The
electrode replacement is now finished.

CAUTION
・ Firmly tighten the torch cap and the torch had by hand.
If a tool is used, the parts of the torch may be damaged.
If the torch cap is firmly tighten, LOST may occur often.
・ Confirm that the screw at the base of power cable and MAWA’s TORCH output is not loose.
If it is loose, the welding current does not flow and LOST may occur often.
・ Do not try to move the torch body with fixing the torch at the torch holder.
The holder is overloaded and may be broken.
