Product Information; Manual Start - Red-D-Arc GX200 Service Manual

PRODUCT DESCRIPTION
The GX200 is a portable engine driven arc welding power source
capable of providing constant current output for stick welding or DC
TIG welding.
GENERATOR
The generator of the GX200 is asynchronous with capacitor
excitation and therefore with excellent mechanical features of
sturdiness and simplicity; it requires no maintenance as it has no
sliding parts such as slip rings and brushes.
The rotor consists of a laminar pack with die cast aluminum stand.
The sizing and setting up of these active parts represent a new
principle which has made the asynchronous generator suitable for
welding services and which has been appropriately patented.
The GX200 has a current range of 40-200 amps with a 60% duty
cycle at 170 Amps. The unit is also capable of providing 2 KVA of
120 VAC and 4KVA of 240 VAC at 60 cycle.
PRE-OPERATION MAINTENANCE
OIL
1 - Remove the oil ller cap and wipe the dipstick clean. 2 - Insert
the dipstick into the oil ller neck, but do not screw it in. 3 - If
the level is low, ll to the top of the oil ller neck with the
recommended oil.
OIL CAPACITY: 1.0 L (34 US oz.)
DO NOT OVERFILL.
FUEL
Fill the fuel tank with the grade of fuel recommended.
LOCATION/VENTILATION
The welder should be located to provide an unrestricted ow of
clean, cool air. Also, locate the welder so that engine exhaust fumes
are properly vented to an outside area.
POLARITY CONTROL AND CABLE SIZES
With the engine o , connect the electrode and work cables of the
appropriate size (see the following table) to the studs located on the
front panel. For positive polarity, connect the electrode cable to the
terminal marked "Positive". For Negative polarity, connect the
electrode cable to the "Negative" stud. These connections should be
checked periodically and tightened if necessary.
When welding at a considerable distance from the welder, be sure
you use ample size welding cables.

PRODUCT INFORMATION

SAFETY SHUTDOWN SYSTEM
All units are equipped with low oil pressure shutdown systems.
Engines should never be operated with shutdown system
disconnected or inoperative.
GENERAL MAINTENANCE
Check all external bolts (engine mounts, generator mounts etc.) at
least once per year and tighten/replace as required.

MANUAL START

1 - Turn the fuel valve to the on position (turn to right)
2 - Close the choke (turn to left)
3 - Turn the throttle control knob until half open
4 - Turn the engine switch to the on position
5 - Pull the start rope lightly until resistance is felt, then pull briskly.
6 - As the engine warms up, gradually move the choke lever to the
open position.
7 - Let the engine run at low speed for 2-3 minutes to warm up.
ELECTRIC START
1-Turn the fuel valve to the on position (turn to right) 2-Close the
choke (turn to left) 3-Turn the throttle control knob until half open. 4-
Turn start key switch to start. 5-As the engine warms up, gradually
move the choke lever to the open position. 6-Let the engine run at
low speed for 2-3 minutes to warm up.
TO TURN OFF THE UNIT
Turn the throttle knob in an counterclockwise direction until the
furthest position, after letting the engine run slowly for a few
seconds, turn the stop switch to the o position * IMPORTANT
Turn the fuel valve to the o position
CONTROL OF WELDING CURRENT
There is one continuous current control for each range which gives
you complete adjustment of current from min. to max. within the
range. There is a low tap for ranges from 40-90Amps, a medium tap
for ranges from 90-170Amps and a high tap for ranges from 160-
195Amps. Always use the lowest possible range with ne current
adjustment closest to max. position.
AUXILIARY POWER
Your GX200 is equipped with AC auxiliary power.
The AC unit provides 1 X 120Volt Duplex receptacle 2KW, and 1 X
120/240Volt twist lock receptacle 4KW, at 60 Hertz power.
The output circuit is protected with a 15Amp circuit breaker for the
120V and a 15Amp circuit breaker for the 240V.
