EMF Information

Considerations About Welding And The Effects Of Low Frequency

Electric And Magnetic Fields

Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such fields. However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National

Research Council concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to powerfrequency electric and magnetic fields is a human-health hazard.”

However, studies are still going forth and evidence continues to be examined. Until the final conclusions of the research are reached, you may wish to minimize your exposure to electromagnetic fields when welding or cutting.

To reduce magnetic fields in the workplace, use the following procedures:

READ INSTRUCTIONS.

D

Use MILLER Testing Booklet (Part No. 150

853) when servicing this unit.

D

Consult the Owner’s Manual for welding safety precautions.

D

Use only genuine MILLER replacement parts.

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 cables around your body.

4.

Keep welding power source and cables as far away from operator as practical.

5.

Connect work clamp to workpiece as close to the weld as possible.

About Pacemakers:

Pacemaker wearers consult your doctor first. If cleared by your doctor, then following the above procedures is recommended.

Control functions as a balance control for

GTAW (TIG) process, and in the DIG mode for SMAW (STICK) process, depending on position of Process control.

Balance Mode:

See Section 3-2.

DIG Mode:

When set lower, short-circuit amperage at low arc voltage is the same as normal welding amperage.

When set higher, short-circuit amperage is increased at low arc voltage to help with arc starting and making overhead or vertical welds, as well as to reduce sticking while welding.

3 Voltmeter (see Section 3-3)

Voltmeter displays voltage (to the nearest 0.1

V) at the weld output terminals, but not necessarily the welding arc due to cable resistance, poor connections, etc.

4 Ammeter (see Section 3-3)

Use ammeter to preset amperage. Meter displays weld amperage output of unit when welding.

5 Amperage Adjustment Control

Turn control clockwise to increase amperage from 5 to 300 amps.

6 Output Control Switch

See Section 3-4.

7 Amperage Control Switch

For front panel control, place switch in Panel position.

For remote control, make connections to remote 14 receptacle, and place switch in

Remote 14 position.

8 Trigger Hold

To start weld, press and release gun trigger within three seconds after an arc has been struck. To end weld, press and release gun trigger. If gun trigger is not released within 3 seconds, unit switches to standard trigger control operation.

9 Process Control

Use control to select either of the GTAW

(TIG) welding process and polarity, or the

SMAW (Stick) welding process.

Selecting any GTAW (TIG) position enables the gas valve, which is disabled when SMAW

(Stick) position is selected.

10 Sequence Control

See Section 3-5.

11 Start A (Amperage) Control

Use control to select a starting amperage that is different from the weld amperage.

12 Start t (Amperage Time) Control

Use control to select length of time in seconds that amperage remains at start amperage before changing to weld amperage.

For example, to select start amperage of 300

A for 3 seconds and weld amperage of 200

A: Set Start A amperage control to 300 A, set

Start t time control to 3 seconds, and set front panel or remote amperage control to 200 A.

13 Crater Control

Control sets length of time in seconds to taper weld output from weld amperage setting to 0 A .

14 Postflow Control

Control sets length of time in seconds gas flows after the welding stops.

Seconds

Do NOT Strike Like A Match!

With Output Switch in Lift On position, start arc as follows:

1 TIG Electrode

2 Workpiece

Touch tungsten electrode to workpiece at weld start point, hold

electrode to workpiece for 1-2

seconds, and slowly lift electrode.

An arc will form when electrode is lifted.

Normal open-circuit voltage is not present before tungsten electrode touches workpiece; only a low sensing voltage is present between electrode and workpiece. The solid-state output contactor does not energize until after electrode is touching workpiece. This allows electrode to touch workpiece without overheating, sticking, or getting contaminated.

With Output Switch in HF Remote position, start arc as follows:

High frequency turns on to help start arc when contactor is energized. High frequency turns off when arc is started, and turns on whenever arc is broken to help restart arc.
