1. RATING PLATE DEFINITIONS
21) - International Protection (IP) rating. The M-227 is 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) - The M-227 is rated as 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 - The M-227, 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 30 amperes
208 VAC + 27%, -13% 50/60 Hz 30 amperes
220 VAC + 20%, -18% 50/60 Hz 30 amperes
230 VAC +15%, -22% 50/60 Hz 30 amperes
240 VAC + 10%, -25% 50/60 Hz 30 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 the M-227 is flat.
Minimum current Output all cases .................... = 3 Amperes DC
Maximum current Output:
Set up for 110 VAC input ............. = 100 Amperes DC continuous or peak pulse.
Set up for 220 VAC input ............. = 200 Amperes DC continuous current
225 Amperes DC peak pulse
NOTE
The M-227 is limited, by software, not to be able to be programmed for an
average current (between primary and background) of greater than 200 Amperes.
However, a peak pulse can be up to 225 amperes as long as the average does
not exceed 200 amperes.
4. CIRCUIT BREAKER - ON/OFF, two pole, 30 Ampere at 250 VAC.
