SECTION III - INSTALLATION
3.1 POWER CONNECTION
2. Install the AC line connector onto the power cord.
NOTE
DO NOT PLUG THE M-227 INTO THE AC POWER SOURCE UNTIL
ALL INSTALLATION STEPS OF THIS MANUAL ARE COMPLETE.
3. Insure that the circuit breaker (CB-1) is in the OFF (down) position (see
figure 3).
4. Using figure 2 and 3 as a reference, locate the power SELECT SWITCH
(next to the input power connector). The switch is concealed by a cover
plate and only the top of the switch handle can be seen through a hole in the
plate. The plate is labeled as to what voltage it is currently set for.
5. If the M-227 is to be run on 100, 110, 115 or 120 VAC, this switch must be
in the 110 VAC position. If it is to be run on 200, 208, 220, 230 or 240
VAC, it must be in the 220 VAC position.
6. To change the power select switch position, remove the cover retaining
screws (see figure 3) and remove the cover. Set the switch to the alternate
position and install the cover plate. It must be flipped over so the hole in the
plate will fit over the switch handle in the new position. This will
automatically expose the alternate voltage label on the other side.
3.2
WELDING GAS CONNECTIONS
1. An Arc Input Gas Hose is supplied with the M-227. This hose is made of
material selected specifically for automatic welding. HOSES MADE
FROM OTHER MATERIAL ARE NOT RECOMMENDED (especially
rubber, nylon or tygon).
2. The 10 foot (3m) hose should be installed from the gas regulator/flowmeter
(user supplied) to the ARC GAS INPUT fittings required to mate with the
M-227 and most domestic (USA) inert gas flow meters.
The arc gas line is controlled by a solenoid and flow sensor in the M-227
and MUST BE connected to the M-227 (not directly to the weld head or
torch). After installing the hose and fittings loosely by hand, tighten the
retaining nuts slightly with a wrench to insure there are no leaks, but do not
over-tighten. The use of plumbers tape or grease is not recommended.
