SECTION III - INSTALLATION
3.1 POWER CONNECTION
2. Install the AC line connector onto the power cord.
NOTE
DO NOT PLUG THE M- 207A INTO THE AC POWER SOURCE UNTIL
ALL INSTALLATION STEPS ARE COMPLETE.
3. Insure that the circuit breaker (CB-1) is in the down or OFF position (see
figure 2 and 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 the switch is currently set for.
5. If the M-207A 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. If it is in the correct position,
proceed to step 3.2.
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
NOTE
The following instructions are for M-207A
1. Three gas hoses are supplied with M-207A. These hoses are made of
material selected specifically for automatic welding. HOSES MADE FROM
OTHER MATERIAL ARE NOT RECOMMENDED (especially rubber,
nylon or tygon).
2. One 10 foot (3m) hose should be installed from the gas regulator/flowmeter
(user supplied) to the ARC GAS INPUT fitting on the M-207A. This hose is
supplied with all fittings required to mate with the M-207A and most domestic
(USA) inert gas flow meters.
