Safe practices have developed from past experience in the use of welding and cutting. These practices must be learned through study and
training before using this equipment. Some of these practices apply to equipment connected to power lines; other practices apply to engine
driven equipment. Anyone not having extensive training in welding and cutting practices should not attempt to weld.
Safe practices are outlined in the American National Standard Z49.1 entitled:
guides to what you should learn before operating this equipment are listed at the end of these safety precautions. HAVE ALL INSTALLATION,
OPERATION, MAINTENANCE, AND REPAIR WORK PERFORMED ONLY BY QUALIFIED PEOPLE.
1.01Arc Welding Hazards
WARNING
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks or
severe burns. The electrode and work circuit is electrically
live whenever the output is on. The input power circuit
and machine internal circuits are also live when power
is on. In semiautomatic or automatic wire welding, the
wire, wire reel, drive roll housing, and all metal parts
touching the welding wire are electrically live. Incorrectly
installed or improperly grounded equipment is a hazard.
SAFETY IN WELDING AND CUTTING. This publication and other
7. Use fully insulated electrode holders. Never dip holder in water to
cool it or lay it down on the ground or the work surface. Do not
touch holders connected to two welding machines at the same
time or touch other people with the holder or electrode.
8. Do not use worn, damaged, undersized, or poorly spliced cables.
9. Do not wrap cables around your body.
10. Ground the workpiece to a good electrical (earth) ground.
11. Do not touch electrode while in contact with the work (ground)
circuit.
12. Use only well-maintained equipment. Repair or replace damaged
parts at once.
13. In confined spaces or damp locations, do not use a welder with
AC output unless it is equipped with a voltage reducer. Use
equipment with DC output.
14. Wear a safety harness to prevent falling if working above floor
level.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating mats
or covers.
4. Disconnect input power or stop engine before installing or
servicing this equipment. Lock input power disconnect switch
open, or remove line fuses so power cannot be turned on
accidentally.
5. Properly install and ground this equipment according to its Owner’s
Manual and national, state, and local codes.
6. Turn off all equipment when not in use. Disconnect power to
equipment if it will be left unattended or out of service.
15. Keep all panels and covers securely in place.
WARNING
ARC RAYS can burn eyes and skin; NOISE can damage
hearing. Arc rays from the welding process produce
intense heat and strong ultraviolet rays that can burn
eyes and skin. Noise from some processes can damage
hearing.
1. Wear a welding helmet fitted with a proper shade of filter (see
ANSI Z49.1 listed in Safety Standards) to protect your face and
eyes when welding or watching.
2. Wear approved safety glasses. Side shields recommended.

ARCMASTER 400 TS
3. Use protective screens or barriers to protect others from flash
and glare; warn others not to watch the arc.
4. Wear protective clothing made from durable, flame-resistant
material (wool and leather) and foot protection.
5. Use approved ear plugs or ear muffs if noise level is high.
WARNING
WARNING
WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc. The flying
sparks and hot metal, weld spatter, hot workpiece, and
hot equipment can cause fires and burns. Accidental
contact of electrode or welding wire to metal objects
can cause sparks, overheating, or fire.
FUMES AND GASES can be hazardous to your health.
Welding produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breath the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to remove
welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instruction for metals, consumables, coatings, and
cleaners.
5. Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Shielding gases used for
welding can displace air causing injury or death. Be sure the
breathing air is safe.
6. Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
7. Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
weld area, the area is well ventilated, and if necessary, while
wearing an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes if welded.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 35 ft (10.7 m) of the welding arc.
If this is not possible, tightly cover them with approved covers.
4. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks or drums.
8. Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.

The following is a quotation from the General Conclusions Section of
the U.S. Congress, Office of Technology Assessment, Biological Effects
of Power Frequency Electric & Magnetic Fields - Background Paper,
OTA-BP-E-63 (Washington, DC: U.S. Government Printing Office, May
1989): “...there is now a very large volume of scientific findings based
on experiments at the cellular level and from studies with animals and
people which clearly establish that low frequency magnetic fields
interact with, and produce changes in, biological systems. While most
of this work is of very high quality, the results are complex. Current
scientific understanding does not yet allow us to interpret the evidence
in a single coherent framework. Even more frustrating, it does not yet
allow us to draw definite conclusions about questions of possible risk
or to offer clear science-based advice on strategies to minimize or
avoid potential risks.”
To reduce magnetic fields in the workplace, use the following
procedures:
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cable around the body.
4. Keep welding power source and cables as far away from
body as practical.
ABOUT PACEMAKERS:
The above procedures are among those also normally
recommended for pacemaker wearers. Consult your
doctor for complete information.

3.0 INSTALLATION RECOMMENDATIONS
3.01 Environment
The ArcMaster 400 TS is designed for use in hazardous environments.
Examples of environments with increased hazardous environments are:
a. In locations in which freedom of movement is restricted, so that the operator is forced to
perform the work in a cramped (kneeling, sitting or lying) position with physical contact
with conductive parts.
b. In locations which are fully or partially limited by conductive elements, and in which there is a
high risk of unavoidable or accidental contact by the operator.
c. In wet or damp hot locations where humidity or perspiration considerably reduces the skin
resistance of the human body and the insulation properties of accessories.
Environments with hazardous environments do not include places where electrically conductive parts
in the near vicinity of the operator, which can cause increased hazard, have been insulated.
3.02 Location
Be sure to locate the welder according to the following guidelines:
In areas, free from moisture and dust.
•
•
Ambient temperature between 0 degrees C to
40 degrees C.
•
In areas, free from oil, steam and
corrosive gases.
•
In areas, not exposed to direct sunlight
or rain.
•
In areas, not subjected to abnormal vibration
or shock.
•
Place at a distance of 12” (304.79mm) or
more from walls or similar that could restrict
natural airflow for cooling.
WARNING 3
Thermal Arc advises that this equipment be electrically connected by a qualified electrician.

3.03 Electrical Input Connections
WARNING 4
ELECTRIC SHOCK can kill; SIGNIFICANT DC VOLTAGE is present after removal of input power.
SHUT DOWN welding power source, disconnect input power employing lockout/tagging procedures.
Lockout/tagging procedures consist of padlocking line disconnect switch in open position, removing fuses
from fuse box, or shutting off and red-tagging circuit breaker or other disconnecting device.
3.03.01 Electrical Input Requirements
Operate the welding power source from a single/three-phase 50/60 Hz, AC power supply. The input voltage
must match one of the electrical input voltages shown on the input data label on the unit nameplate. Contact
the local electric utility for information about the type of electrical service available, how proper connections
should be made, and inspection required.
The line disconnect switch provides a safe and convenient means to completely remove all electrical power
from the welding power supply whenever necessary to inspect or service the unit.
Note 2
This unit is equipped with a three-conductor with earth power cable that is connected at the
welding power source end for single and three phase electrical input power.
Do not connect an input (WHITE or BLACK or RED) conductor to the ground terminal.
Do not connect the ground (GREEN) conductor to an input line terminal.
Refer to Figure 3 and:
1. Connect end of ground (GREEN) conductor to a suitable ground. Use a grounding method that complies
with all applicable electrical codes.
2. Connect ends of line 1 (BLACK) and line 2 (WHITE) and line 3 (RED) input conductors to a de-energized line
disconnect switch.
3. Use Table 1 and Table 2 as a guide to select line fuses for the disconnect switch.
Note 3
For Single-Phase operation connect the GREEN, BLACK and WHITE input conductors. Insolate the
RED Conductor, it is not used for Single-phase operation.

3.03.03 High Frequency Introduction
The importance of correct installation of high frequency welding equipment cannot be over-emphasized.
Interference due to high frequency initiated or stabilized arc is almost invariably traced to improper
installation. The following information is intended as a guide for personnel installing high frequency
welding machines.
Warning
Explosives
The high frequency section of this machine has an output similar to a radio transmitter. The machine
should NOT be used in the vicinity of blasting operations due to the danger of premature firing.
Computers
It is also possible that operation close to computer installations may cause computer malfunction.
3.03.04 High Frequency Interference
Interference may be transmitted by a high frequency initiated or stabilized arc welding machine in the
following ways:
Direct Radiation
Radiation from the machine can occur if the case is metal and is not properly grounded. It can occur
through apertures such as open access panels. The shielding of the high frequency unit in the Power
Source will prevent direct radiation if the equipment is properly grounded.
Transmission via the Supply Lead
Without adequate shielding and filtering, high frequency energy may be fed to the wiring within the
installation (mains) by direct coupling. The energy is then transmitted by both radiation and conduction.
Adequate shielding and filtering is provided in the Power Source.
Radiation from Welding Leads
Radiated interference from welding leads, although pronounced in the vicinity of the leads, diminishes
rapidly with distance. Keeping leads as short as possible will minimize this type of interference.
Looping and suspending of leads should be avoided where possible.
Re-radiation from Unearthed Metallic Objects
A major factor contributing to interference is re-radiation from unearthed metallic objects close to the
welding leads. Effective grounding of such objects will prevent re-radiation in most cases.

Thermal Arc continuously strives to produce the best product possible and therefore reserves
the right to change, improve or revise the specifications or design of this or any product without
prior notice. Such updates or changes do not entitle the buyer of equipment previously sold or
shipped to the corresponding changes, updates, improvements or replacement of such items.
17
3.05 Duty Cycle
The duty cycle of a welding power source is the percentage of a ten (10) minute period that it can be
operated at a given output without causing overheating and damage to the unit. If the welding amperes
decrease, the duty cycle increases. If the welding amperes are increased beyond the rated output, the
duty cycle will decrease.
WARNING 5
Exceeding the duty cycle ratings will cause the thermal overload protection circuit to become
energized and shut down the output until the unit has cooled to normal operating temperature.
CAUTION 1
Continually exceeding the duty cycle ratings can cause damage to the welding power source and
will void the manufactures warranty.
NOTE 5
Due to variations that can occur in manufactured products, claimed performance, voltages, ratings,
all capacities, measurements, dimensions and weights quoted are approximate only. Achievable
capacities and ratings in use and operation will depend upon correct installation, use, applications,
maintenance and service.

5.0 SET-UP FOR SMAW (STICK) AND GTAW (TIG)
Conventional operating procedures apply when using the Welding Power Source, i.e. connect work lead
directly to work piece and electrode lead is used to hold electrode. Wide safety margins provided by the coil
design ensure that the Welding Power Source will withstand short-term overload without adverse effects.
The welding current range values should be used as a guide only. Current delivered to the arc is dependent
on the welding arc voltage, and as welding arc voltage varies between different classes of electrodes,
welding current at any one setting would vary according to the type of electrode in use. The operator should
use the welding current range values as a guide, then finally adjust the current setting to suit the application.
WARNING 7
Before connecting the work clamp to the work and
inserting the electrode in the electrode holder make
sure the Primary power supply is switched off.
CAUTION 3
Remove any packaging material prior to use. Do not
block the air vents at the front or rear or sides of the
Welding Power Source.
CAUTION 4
DO NOT change the Weld Mode or Weld Process Mode
Until after POST-FLOW time has finished.

Slope function operates with a Remote ON/OFF device only.
1) To start Slope sequence Close remote switch contacts. Once the welding arc is established the Power
Source will maintain initial current setting as long as the remote switch contacts are closed.
a) In the HF TIG mode, after Preflow time High Frequency is present at the torch. When the torch is
positioned close to the work the welding current will transfer to the work and establish the arc at the
initial current setting.
b) In the Lift TIG mode, after preflow time Lift Start current is present at the torch. When the electrode
is touched to the work and lifted off, the welding arc is established at the initial
current setting.
2) Open Remote Switch – current increases to weld current. Once welding arc has reached weld
current the power source will maintain weld current as long as the remote switch contacts are open.
3) Close Remote Switch – Welding current decreases to final current setting. Once final welding current
is reached the power source will maintain final current setting as long as the remote switch contacts
are closed.
4) Open Remote Switch – Welding arc stops and post flow begins.
6.02.02 Slope Mode with Repeat Sequence
The repeat function is operated during the down slope cycle of the Slope Sequence and is active through the
down slope period only. During the down slope period by opening the Remote Switch contacts the current
will increase back to weld current. Within the Down Slope period the repeat function can be operated as
many times as desired. To continue slope cycle and end slope sequence close remote switch contacts and
allow weld current to reach final current setting. Once final current setting is reached opening the Remote
Switch again will turn off the welding arc and post flow begins.

6.02.03 Pulse Controls
The Pulse controls are used primarily to control heat input. Pulse offers a number of advantages
as follows:
1) Control puddle – size and fluidity (especially out of position).
2) Increase penetration
3) Travel speed control
4) Better consistent quality
5) Distortion on lighter or thinner materials.
Pulse-current provides a system in which the welding current continuously changes between two levels.
During the periods of Peak current, heating and fusion takes place, and during the background (base) current
periods, cooling and solidification take place. Pulse Width is the time in one cycle the current stays at the
peak current setting. Pulse Frequency measured in Hertz is the number of cycles per second the current
travels between peak and background current settings. It is as if the foot rheostat were moved up and down
to increase and decrease the welding current on a regular basis. The faster you moved the foot rheostat up
and down the faster the frequency.

7.0 BASIC TIG WELDING GUIDE
7.01 Electrode Polarity
Connect the TIG torch to the - /
current straight polarity. Direct current straight polarity is the most widely used polarity for DC TIG welding.
It allows limited wear of the electrode since 70% of the heat is concentrated at the work piece.
Stick electrodes are generally connected to the ‘+’ terminal and the work lead to the ‘−’ terminal but if in
doubt consult the electrode manufacturers literature.
8.02 Effects of Stick Welding Various Materials
High tensile and alloy steels
The two most prominent effects of welding these steels are the formation of a hardened zone in the weld
area, and, if suitable precautions are not taken, the occurrence in this zone of under-bead cracks. Hardened
zone and under-bead cracks in the weld area may be reduced by using the correct electrodes, preheating,
using higher current settings, using larger electrodes sizes, short runs for larger electrode deposits or
tempering in a furnace.
Manganese steels
The effect on manganese steel of slow cooling from high temperatures is to embrittle it. For this reason it
is absolutely essential to keep manganese steel cool during welding by quenching after each weld or skip
welding to distribute the heat.
Cast Iron
Most types of cast iron, except white iron, are weldable. White iron, because of its extreme brittleness,
generally cracks when attempts are made to weld it. Trouble may also be experienced when welding whiteheart malleable, due to the porosity caused by gas held in this type of iron.
Copper and alloys
The most important factor is the high rate of heat conductivity of copper, making preheating of heavy
sections necessary to give proper fusion of weld and base metal.
Types of Electrodes
Arc Welding electrodes are classified into a number of groups depending on their applications. There are a
great number of electrodes used for specialized industrial purposes which are not of particular interest for
everyday general work. These include some low hydrogen types for high tensile steel, cellulose types for
welding large diameter pipes, etc. The range of electrodes dealt with in this publication will cover the vast
majority of applications likely to be encountered; are all easy to use and all will work on even the most basic
of welding machines.

9.0 ROUTINE MAINTENANCE
The only routine maintenance required for the power supply is a thorough cleaning and inspection, with the frequency
depending on the usage and the operating environment.
The unit should be wiped clean as necessary with solvents that are recommended for cleaning electrical apparatus. Turn
Power Switch to OFF before proceeding. Internal cleaning of the unit should be done every 6 months by an authorized
Thermal Arc Service Center to remove any accumulated dirt and dust. This may need to be done more frequently under
exceptionally dirty conditions.
CAUTION 5
Do not blow air into the power supply during cleaning. Blowing air into the unit can cause metal particles
to interfere with sensitive electrical components and cause damage to the unit.
