Exothermic Welding

New technology from Kumwell for electric ignitor with low smoke

exothermic welding system.

Filter Cover

- Replaceable special filter cover designed for low smoke exothermic

mould without starting power required

ELITOR system is designed to simplify and safety operation for exother-

mic welding with remote operationg ignition.- More reliable ignition than conventional flint gun

- No external power or starting power required and resulting less

- Convenience and flexible to work in restricted or closed area

- Rechargeable battery with LED display

- Quick action and easy to handle

- Warning sound before ignition for safety operation

Low Smoke Exothermic Welding System

with Electric Ignitor and warning sound for safety operation

Elitor System

Insert the connector withPCB ignitor strip on the sidehole of the mould lid.

Press the “IGNITOR” button onhold until alarm 5 Sec.exothermic reaction is

initiated. Place “OFF” button

PCB IGNITOR STRIP Code No. KTA023

ELITOR ELECTRIC IGNITER Code No. KTA024

Specifications

- Power : 6 V/DC, type Sealed Lead - acid battery

- On/Off power SW saperate from ignite SW.

- Starting Ignition 4.8 V/DC 2.3 - 2.5 A- Charger control and LED display

- DC Adaptor charger 9 VDC 2A

- Remote operation with 2 meter cable and control box

- Operating temperature : 5oC - 60

- Safety warning sound alarm 5 sec. before ignition

- Ignition capacity when battery full charge more than 70 time

Caution

- Please Off power SW when not in operation to save the battery

- Exothermic Mould and battery design by manufacturer

- PCB strip hole alignment varies from connection types to

conductor size.- Please don’t switch ELITOR ON/OFF without PCB strip since

ELITOR will be malfunction resulting short life time.

alarm 5 sec.exothermic reaction is

initiated. Place“ OFF ” button

Pour a recommended size of weld metal

into the mould crucible Check for leaks

of weld metal Repeat step 4 in case of leak

Insert the PCB ignitor strip into the connector

of Elitor Ignitor

Then, clean the surface of conductor with

a cable clean brush and/or preheat with

butance torch again in order to ensure

that conductor is entirely dry

Place conductor into the mould snugly,

leave the space 2-3 mm. between the

end of conductors for better molten copper

alloy flow. Then, tighten handle clamp.

Kumwell is new technology for electric ignition.ELITOR It is designed to simplify and safety operation forexothermic welding with remote operation ignition.- More reliable ignition than conventional flint gun- Convenience and flexible to work in restricted or closed area- Rechargeable battery with LED display- Quick action and easy to handle- Safety warning sound before ignition

Specifications

- Power : 6 V/DC, type Sealed Lead - acid battery- On/Off power SW saperate from ignite SW.- Starting Ignition 4.8 V/DC 2.3 - 2.5 A- Charger control and LED display- DC Adaptor charger 9 VDC 2A- Remote operation with 2 meter cable and control box- Operating temperature : 5

oC - 60

- Safety warning sound alarm 5 sec. before ignition- Ignition capacity when battery full charge more than 70 time

Caution- Please Off power SW when not in operation to save the battery life.

- Exothermic Mould and battery design by manufacturer - PCB strip hole alignment varies from connection types to conductor size.- Please don’t switch ELITOR ON/OFF without PCB strip since ELITOR will be malfunction resulting short life time.

INSTRUCTION

Check mould tag to be welded and propercartridge size. Assembly mould and handleclamp with bolt and preheat with a butanetorch to ensure that mould is entirely dry

Insert the steel disc to seat on cavity

properlyPour weld metal powder into the mould

If notice powder leakage, please return to

step 4 again and pour starting powder on

surface metal powder.

Pour starting powder into hole on top of

mould lid.

Place conductor into the mould snugly,

leave the space 2-3 mm. between the end

of conductor for better molten copper alloy

flow.Then, tighten handle clamp.

Insert the connector with PCB ignitor

strip on the side hole of the mould lid.Switch the power button to the “ ON ”

position

insert the PCB KTA 023SP ignitor strip

into the connector of ELITOR IGNITOR

Completed Kumwell connectionPress the “IGNITOR” button on hold until

alarm 5 Sec. exothermic reaction is

initiated. Place “OFF” button

Then, clean the surface of conductor with

a cable clean brush and/or preheat with

butance torch again in order to ensure that

conductor is entirely dry

After completed reaction, wait for 2-3

minutes to cool down before removing

weld connection. Open the mould,

remove slag with scrapper and clean with

the mould brush.
