SO NOW WHAT?SO NOW WHAT?

We are here to help you Purpose of this presentation is to answer

any questions you have What are your top questions? At a minimum you need to change your

tips, regulators and use T grade hoses Let’s learn more…

CHANGE IS GOODCHANGE IS GOOD Time is right to make the change to alternate

fuel Harris is ready to help with the right

equipment and technical know how Harris has been making alternate fuel

equipment for over 105 years Once you learn the benefits of our injector

technology you’ll be ready to make the change

ALTERNATE FUELS SAVE MONEYALTERNATE FUELS SAVE MONEY

Savings up to 40% versus Acetylene

More BTU’s per dollar Lower cylinder handling costs Lower cylinder rental charges Equipment will last longer

SAVE WITH ALTERNATE FUELSSAVE WITH ALTERNATE FUELS

Acetylene

Alternate Fuel

5

ALTERNATE FUELS PERFORMALTERNATE FUELS PERFORM

More BTU’s per cubic foot Less chipping and grinding Less top edge roll-over Very broad flame adjustment

range Less hardening of cut face

6

ALTERNATE FUELS ARE CONVENIENTALTERNATE FUELS ARE CONVENIENT

More product per cylinderLess weight per cylinderFewer cylinder changes80% less floor space neededReadily available

7

ALTERNATE FUELS ARE SAFEALTERNATE FUELS ARE SAFE

Highly resistant to flashback and backfire

Can be used at higher pressures Less U.V. protection required Not sensitive to shock

8

NOT ALL TORCHES ARE CREATED EQUALNOT ALL TORCHES ARE CREATED EQUAL Harris alternate fuel torches use injector mixers You get reduced pre-heat times and more BTU’s Injector mixers create a homogenous blend This blend allows for greater combustion efficiency

Equal pressure torches will never achieve this performance especially if you only change out the tip

“F” Injector Technology

THE DIFFERENCE BETWEEN TORCHESTHE DIFFERENCE BETWEEN TORCHES

“E” Equal Pressure

With an injector torch you only need to adjust the

oxygen valve to increase/decrease flame intensity

10

DID YOU KNOW?DID YOU KNOW?

Alternate fuels cut much better than acetylene when you have the right equipment

Remember, the oxygen does the cutting, not the fuel gas

GET THE RIGHT TORCHGET THE RIGHT TORCH

Be sure you have an injector style torch Harris model 62-5F works best Take advantage of the benefits of

alternate fuels Pick the torch that meets your needs

GET THE RIGHT TIPGET THE RIGHT TIP

Pick the right tip for optimum performance

All tips are not created equal Every Harris tip is tested 100% for

quality Our two-piece 6290 tips are specifically

designed for the alternate fuel of your choice

LIGHTING AN INJECTOR “F”TORCHLIGHTING AN INJECTOR “F”TORCH1. Purge both oxygen and fuel gas lines – separately and

reclose valves

2. Open oxygen & fuel gas valves 1/3 - 1/2 turn

3. Ignite flame with approved lighter

4. Increase fuel gas flow until flame is slightly carburizing

5. Open oxygen valve and adjust to obtain the desired flame

6. For optimum cutting – focus on a star pattern & sound

7. Depress oxygen lever and make adjustments if necessary

SHUTTING DOWN AN INJECTOR TORCHSHUTTING DOWN AN INJECTOR TORCH

1. Close fuel gas torch valve

2. Close oxygen torch valve

3. Close down system (cylinders):1.Close oxygen & fuel gas cylinder valves

2.Separately purge oxygen & fuel gas lines

then close valves Make sure all regulator gauges read “0” Back out regulator P/A screws! Report any damage, etc. to Supervisor

21

LIGHTING AN EQUAL PRESSURE“E”TORCHLIGHTING AN EQUAL PRESSURE“E”TORCH

1. Purge both oxygen and fuel gas lines – separately and reclose valves

2. Open fuel gas valve 1/8 to 1/4 turn

3. Ignite flame with an approved lighter

Note: Refer to AWS C4.2

1. Increase fuel gas flow until flame leaves end of tip

2. Decrease until flame goes back to tip

3. Open oxygen valve and adjust to neutral flame

4. For optimum cutting – focus on a star pattern & sound

5. Depress oxygen lever and make adjustments if necessary

22

SHUTTING DOWN AN “E” TORCHSHUTTING DOWN AN “E” TORCH

1. Close oxygen torch valve2. Close fuel gas torch valve3. Note: To close down system (cylinders). Close oxygen & fuel gas cylinder valves Separately bleed oxygen & fuel gas lines Close each valve after purging Make sure all regulator gauges read “0” Back out regulator P/A screws! Report any damage, etc. to Supervisor
