CHIEF 2000 HERTZ DC INVERTER WELDER
USERS MANUAL
Setting Up Welder
1. Make sure main switch at front of machine and
breaker at rear of machine are both in “off” position.
IMPORTANT: A qualified electrician must perform
the following:
• If machine will be used with three-phase supply, hard
wire it to connecting box or plug it to a 208/230 V
socket (3 phases + ground) with a minimum power of
50 amps, supplied by leads of at least 10 gauge.
• If machine will be used on single phase supply,
only two of the phase conductors will be used. Each
of the three phase conductors are identified by num-
ber (1, 2 or 3). For single phase supply, cut the end
of conductor number 3 and insulate it. Then hard
wire conductors 1 and 2 to a connecting box or to a
plug connected to a socket (208 / 230 V - single
phase + ground) with a minimum power of 60 A sup-
plied by leads of at least 8 gauge.
2. Drain air supply line.
3. Connect the compressed air hose (with quick coupler)
to the air connector on back side of welding unit.
4. Set air pressure of line at 70 psi or 5 BAR.
5. Place breaker at rear of machine in “on” position.
6. Turn main switch on front panel (clockwise) to “on” posi-
tion. DO NOT leave switch on positions “1” or “2”. Only
use “on” and “off”.
7. Press button in lower right hand corner of control panel
to switch control unit “on”. (See letter A at right.)
8. Press pincer gun selection key. (See letter B at right.)
9. Operate pincer gun by pulling trigger located under the
handle. Electrodes should close. Then press trigger
located on top of handle. Electrodes should open wide.
CAUTION: Double-sided gun and single-sided pistol
are connected to current output.Welding can only be
done when correct gun is used with correct mode
setting. However, because the two tools are simulta-
neously supplied with current, it is important that
precautions be followed. When using double sided
gun, make sure single sided pistol and ground shoe
cable are placed on their supports and can not
touch each other. When using welding pistol, the
double- sided gun must be placed on its support.
