1. RATING PLATE DEFINITIONS
21) - International Protection (IP) rating. M-207A and M-207A-1 are rated
IP21 which includes protection against a limited amount of exposure to
rain (does not make it weather proof or intended for all weather usage).
.
22) - All M-207A models are class I. No symbol is used for class I
equipment.
23) - “S” Symbol indicates a welding power source which is suitable for an
environment with an increased electric shock hazard.
2. INPUT POWER, DETAIL - All M-207A Models, as shipped standard, can
operate on the following Single Phase input AC:
Voltage Tolerance Freq. Max Input Current
100 VAC + 32%, -10% 50/60 Hz 30 amperes
110 VAC + 20%, -18% 50/60 Hz 30 amperes
115 VAC + 15%, -22% 50/60 Hz 30 amperes
120 VAC + 10%, -25% 50/60 Hz 30 amperes
200 VAC + 32%, -10% 50/60 Hz 20 amperes
208 VAC + 27%, -13% 50/60 Hz 20 amperes
220 VAC + 20%, -18% 50/60 Hz 20 amperes
230 VAC +15%, -22% 50/60 Hz 20 amperes
240 VAC + 10%, -25% 50/60 Hz 20 amperes
+/- % indicates the allowable input voltage change to maintain performance as
specified. Maximum input current is based on maximum output current at
maximum arc voltage. See section 3.1 for installation.
3. OUTPUT POWER - Straight polarity, constant current DC regulation intended
for GTAW welding only. Static characteristic of all power supplies is flat.
All Models ................... = 3 to 100 amperes DC using 100 to 120 VAC input.
M-207A-1 = 3 to 100 amperes DC using 200 to 240 VAC input.
M207A ......................... = 3 to 150 amperes DC using 200 to 240 VAC input.
