These INSTRUCTIONS are for experienced operators. If you are not fully familiar with the principles of operation and safe practices for

arc welding equipment, we urge you to read our booklet, "Precautions and Safe Practices for Arc Welding, Cutting, and Gouging,"

Form 52-529. Do NOT permit untrained persons to install, operate, or maintain this equipment. Do NOT attempt to install or operate

this equipment until you have read and fully understand these instructions. If you do not fully understand these instructions, contact

your supplier for further information. Be sure to read the Safety Precautions before installing or operating this equipment.

I. INTRODUCTION

The ST-16 Torch, P/N 997498, is a rugged all purpose,

water cooled, manual Mig welding torch designed to

operate at welding currents up to 600 amperes continu-

ous duty using argon as the shielding gas. The ST-16 is

intended for use with ESAB wire feeders which have

provision for water cooling and will handle all types of

welding wires in sizes from .030-in. through 7/64-in. di-

ameter.

II. DESCRIPTION

To provide maximum resistance to the abuses of day to

day service, the torch is of heavy-duty construction with

metal parts well insulated from current carrying mem-

bers. It’s 55-degree, curved stainless steel front body

permits effective operation in tight, hard-to-reach cor-

ners and other contained areas. The torch employs metal

nozzles and either slip-in contact tubes or threaded con-

tact tips (long or short). Each contact tube is threadless

and is retained by a collet nut supplied with the torch.

All service lines are internally connected to the torch

body and exit from the rear of the torch handle for easy

torch maneuverability. For weld start-stop control, the

torch is provided with a positive action universal lever

switch which can be positioned at any point on the torch

handle preferred by the operator.

For feeding all wires, a self-lined conduit with either a

spring or plastic jumper liner is normally used. An alter-

nate replaceable liner conduit system is also available

for feeding 0.35, .045 and 1/16-in. hard wires through a

continuous metal conduit liner.

III. ACCESSORY EQUIPMENT

A. REQUIRED

The ST-16 requires a nozzle (see Table 1), and several

wire feed accessories of the proper size for the wire be-

ing used. (Refer to Table 2 if using the self-lined conduit

system or Table 3 if using conduit with continuous or

replaceable liner system). One other accessory whose

selection depends upon wire size is the feed roll on the

wire feeder itself. Selection of this accessory is covered

in the appropriate wire feeder instruction booklet.

Centering Bushing, P/N 994330 (For use with No.8

and No. 10 nozzles) - Eliminates any possibility of

spatter bridging in the torch. This is accomplished

by using this one-piece centering bushing and spat-

ter liner in place of the two individual pieces nor-

mally used. Note that it can only be used at maxi-

mum current of 350 amps with argon or 550 amps

with C0
