Safety Precautions

Read entire section before starting installation

WARNING!

Electric Shock can kill – Only qualified personnel should perform this installation. Turn off input

power at the fuse box before working on this equipment. Do not touch electrically live parts. Always

connect the machine to an earthed mains supply as per national recommended standards.

Select suitable location

Place the welder where clean cooling air can freely circulate in and out of the front & rear vents.

Dirt, dust or any foreign material that can be drawn through vents into welder must be kept to a

minimum. Failure to observe these precautions can result in excessive operating temperatures

which can lead to plant failure.

Grinding

Do not direct grinding particles towards the welder. An abundance of conductive material can cause

plant failure.

Stacking

This machine cannot be stacked.

Transport – Unloading

Never underestimate the weight of equipment, never move or leave suspended in the air above

people. Use recommended lifting equipment at all times.

WARNING!

Falling Equipment can cause injury. Never lift welder with gas bottle attached. Never lift above

personnel.

Tilting

Machine must be placed on a secure level surface or on a recommended undercarriage/trolley.

This machine may topple over if this procedure is not followed.

Environmental Rating

The welding power source carries the IP21S rating. It may be used in normal industrial and

commercial environments. Avoid using in areas where water / rain is around.

Read and follow the ‘Electric Shock Warnings’ in the safety section if welding must be performed

under electrically hazardous conditions such as welding in wet areas or water on the work piece.

Machine grounding and Interference Protection

This welder must be grounded to earth. See national electrical codes for proper grounding

methods.

Radiated interference can develop in the following ways

1. Direct interference from welder power source

2. Direct interference from the welding leads

3. Direct interference radiated from feedback into power lines

4. Interference from re-radiation by un-grounded metallic objects.

Keeping these contributing factors in mind, installing equipment as per following instructions should

minimize problems.

1. Keep the welder input power lines as short as possible and enclose as much of them as

possible in metal conduit or equivalent shielding. There should be a good electrical contact

between this conduit and ground (Earth).

2. Keep the work and electrode leads as short as possible. Length should not exceed 25FT.

Tape the leads together where practical.

3. Be sure the torch and earth leads rubber coverings are free from cuts and cracks that allow

high frequency leakage

4. Keep the torch in good repair and all connections tight to reduce leakage

5. Keep earth lead connection to work in good condition – Clean area on workbench where

earth clamp is situated on a regular basis.

Input Connections

Make sure the voltage, phase and frequency of input power is as specified on machine rating plate

located at rear of machine.

Have a qualified electrician provide suitable input power as per national electrical codes. Make sure

machine is earthed / grounded.

Make sure fuse or circuit breaker is correct rating for machine. Using fuses or circuit breakers

smaller than recommended will result in ‘nuisance’ shut off from welder inrush currents even if

welding at low amperages.

On multiple voltage input welders, be sure the machine is connected as per the instructions for the

voltage being supplied to welder – Failure to follow these instructions can cause immediate failure

within the welder and void machines warranty.

WARNING!

ELECTRIC SHOCK CAN KILL

Turn the input power OFF at the mains switch & fuse box before working on this equipment.

Have a qualified electrician install & service this equipment.

Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before

working inside this equipment.

Do not touch electrically live parts

The PROARC135 Inverter Welder requires a 240V 16A 50/60Hz supply (at 125 amps output it will

draw 13A input, if used on a 13Amp plug you may get nuisance fuse blows when welding at

maximum amperage). It comes with a 2 metre mains cable attached.

Connect wires according to national coding.

Brown wire – Live

Blue wire – Neutral

Green/Yellow Wire – Earth (Ground)

Front machine connections

1. Negative welding power connector

Connect the earth cable dinse plug into here and twist to secure

2. Positive welding power connector

Connect the electrode holder cable dinse plug into here and twist to secure

Most popular rods require positive welding electrode and negative earth. If you are using special

electrodes please check manufacturer’s recommendation for correct polarity of welding electrodes

and connect as required.

Controls and Settings

1. Current Control Knob

This selects the welding power and is shown in LED display (3)

2. Warning indicator light

Lights RED when over-heat thermostat protection has occurred, due to over work or poor

airflow. Fan will continue to run and once machine has cooled down light will go off and

machine is ready to use.

Note: This light will come on for 1-2 seconds when first turned on and then will go off once

start up self test has finished.

3. Display LED

This LED shows the selected welding current.

SAFETY PRECAUTIONS

WARNING!

ELECTRIC SHOCK CAN KILL

Do not touch electrically live parts or electrode with skin or wet clothing.

Insulate yourself from work and ground

Always wear dry insulating gloves

WARNING!

FUMES AND GASES can be dangerous

Keep your head out of fumes & gases produced from welding.

Use ventilation or exhaust to remove fumes & gases from breathing zone and general area.

WARNING!

WELDING SPARKS can cause fire or explosion

Keep flammable material away from work area.

Do not weld on containers that have held combustibles

WARNING!

ARC RAYS can burn

Wear eye, ear and body protection – Make sure work area is protected by proper shielding to

avoid injury to passers by.
