No, mig works this way. Wire speed=amps=penetration. Heat=arc volts=bead shape. The rule of thumb is 1 amp for each 0.001 inch of stock thickness. 1/8 inch = 0.125 inches, 0.125/0.001 = 125 amps. What wire speed gives what current?
Wire dia..........amps/inch/min........amp range:confused3:
0.025....................3.5.......................30--90
0.030....................2..........................40--145
0.035....................1.6.......................50--180
0.045....................1..........................75--250
125 amps falls in the range of the 0.030, 0.035 and 0.045 dia wires.:confused2:
0.030 wire;
125 amp x 2 = 250 in/min or 25 in. in 6 seconds.
0.035 wire;
125 amps x 1.6 = 200 in/min or 20 in. in 6 seconds.
0.045 wire;
125 amps x 1 = 125 in/min or 12.5 in. in 6 seconds.
Therefore all three wires are suitable. The best choice is the 0.035 wire because 125 amps are the closest to the mid range. :thumbsup:
Heat [voltage] is determined from the chart in the mig for the type of wire and the stock thickness.
Tap or dial setting, A B C; 4 5 6.
These settings will get you into the ballpark and you will still need to tune-in for the best results.
Hint; some wire manufactures list the voltage, current, wire speed range for each thickness of the stock. :cool2:
Hint; stock more than 1/8 in. thick should be V notched.:dance1:
