Protect yourself and others from flying sparks and hot metal.
Do not spot weld where flying sparks can strike flammable material.
Remove all flammables within 35 ft (10.7 m) of the weld. If this is not
possible, tightly cover them with approved covers.
Be alert that welding sparks can easily go through small cracks and
openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Do not spot weld on closed containers such as tanks or drums.
Do not weld where the atmosphere may contain flammable dust,
gas, or liquid vapors (such as gasoline).
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.

Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
Welding current 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
OM-745 Page 2
committee of the National Research Council concluded that: “The body
of evidence, in the committee’s judgment, has not demonstrated that
exposure to power-frequency electric and magnetic fields is a humanhealth hazard.” However, studies are still going forth and evidence
continues to be examined.

Tongs
. Tong pressure
1
must be checked and/or set before operation.
Correct tong pressure is necessary to create a quality weld and to
prevent damage to tips.
2
Too much tong pressure causes the weld nugget to dimple and material to splash out around the nugget area.
5
4
Step 1
If tong pressure is too weak, parts are loose when the tongs are
closed, severe arcing occurs between workpieces, and no weld
can be made.
Step 2
Loosen both nuts and
push tong tips together.
Air Supply On
Step 3
Begin to tighten top nut. This causes tong tips to
open. Stop when opening is a little less than thickness of material to be welded. Tighten bottom nut.
Step 4
Set controls.
Step 5
Start
OR
Place material to be welded between
tong tips, and press start switch or remote foot control (see Section 3-1).
Step 6
If tong pressure appears correct, place Weld switch in Weld
position and try a sample weld according to Section 3-1.
Step 7
Step 8
Air Supply
Off
Set controls. If tong pressure is
correct, stop here. If further adjustment is required, go to next step.
To INCREASE tong pressure, loosen top
nut 1/4 turn. Tighten bottom nut, turn air
and Power On, and go to Step 4.
To DECREASE tong pressure, loosen bottom nut 1/4 turn. Tighten top
nut, turn air and Power On, and go
to Step 4.

1 Time Control
Squeeze Time (ST) - Use control to set
enough time for tongs to close and apply full
pressure to the work before weld amperage
starts. Push ST button, then use buttons 3,
2, 1 to select squeeze time from 0 to 9.99 seconds. Squeeze time begins when the Remote Foot Switch or Start Switch is pressed.
Weld Time (WT) - Push WT button, then use
buttons 3, 2, 1 to select spot weld time from
0 to 9.99 seconds.
Weld time begins at the end of the squeeze
time cycle.
2 Weld Switch
Use control to check tong pressure and
alignment without weld amperage present at
the tongs. When the switch is in the Set Up
position, pressing the Remote Foot Switch
or Start Switch closes the tongs without
starting weld amperage. When the switch is
in the Weld position, tongs have weld amperage present after the squeeze time has
ended.
3 Weld Amperage Control
Turn clockwise to increase current. Changing the weld current value does not affect the
duty cycle rating. The scale is for reference
only.
4 Power/Pilot Light/Circuit Breaker
Switch
Use switch to turn On power and pilot light.
See Section 4-2 for circuit breaker operation.
5 Fuse F1
See Section 4-2.
6
Start Switch/Remote Foot Switch
Use Start Switch (Portable Models)/Remote
Foot Switch (Stationary Models) to close
tongs and start squeeze time.
If switch is released before squeeze time
ends, the tongs open, and the unit resets for
another weld cycle.
If switch is held until squeeze time ends and
weld time starts, the switch may be released,
and the tongs will stay closed until weld time
ends.
If workpiece is to be left between tongs after
weld time ends, switch must be held for
whatever hold time is desired after welding
ends.

MILLER PRODUCTS ARE INTENDED FOR PURCHASE

In the event of a warranty claim covered by this warranty, the

Miller. Therefore no compensation or reimbursement for
transportation costs of any kind will be allowed.
TO THE EXTENT PERMITTED BY LAW, THE REMEDIES
PROVIDED HEREIN ARE THE SOLE AND EXCLUSIVE
REMEDIES. IN NO EVENT SHALL MILLER BE LIABLE FOR
DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF
PROFIT), WHETHER BASED ON CONTRACT, TORT OR
ANY OTHER LEGAL THEORY.

Some states in the U.S.A. do not allow limitations of how long
an implied warranty lasts, or the exclusion of incidental,
indirect, special or consequential damages, so the above
limitation or exclusion may not apply to you. This warranty
provides specific legal rights, and other rights may be
available, but may vary from state to state.

additional warranties or remedies other than as stated herein,
