Arc voltage ( volts affects puddle fluidity) Starting the arc : 50-100 volts Maintaining arc : 17-40 volts |
Amperage •metal deposition rate ( burn off rate) •penetration |
|
|
Smaw welding machines • generators = AC or DC output • transformers= (buzzbox) AC only (Rectifier) AC & DC output • inverters = multipurpose AC &/or DC Smaw needs CC ( constant current) T |
DCEP= reverse polarity DCEN= straight polarity |
|
|
Arc length! Short arc length = volts ⬇️ amps ⬆️ narrow high bead, deeper pen. Long arc length= volts ⬆️ amps ⬇️ flat wider bead, shallow pen. |
CC = SMAW, GTAW Consumable* CV= GMAW, FCAW Saw = CV or CC |
|
|
SMAW is cc, DCEP , drooping volt amp curve, Coated electrodes |
GMAW is CV, DCEP, flatter volt amp curve |
|
|
FCAW is CV, DCEP, Tubular electrode, gas shield, self shielded |
GTAW is CC, DCEN |
|
|
SAW CV or CC, AC or DCEP |
CAC-A is CC, DCEP on mild steel & aluminum and CI and DCEN on SS, electrode stickout 7”, 4” on aluminum |
|
|
PAW is CC, DCSP, ocv is 80 volts, electrode same as GTAW ( tungsten) PAC is CC, DCSP, ocv is 120-400 volts, electrode zirconium Or hafnium |
SMAW electrodes E6010 = F3, DCRP, cellulose, deep pen, fast freeze, dynamic loading. E6013= F2, AC or DC, rutile, fill freeze, static loading. E7018= F4, AC or DCRP, lime, low hydrogen, dynamic loading. E7024= F1, AC or DC, iron powder, fast fill, static loading. |
|
|
Cable sizes smallest to largest 4, 3, 2, 1, 1/0, 2/0, 3/0, 4/0 Larger size= less electrical resistance |
|
|
Smaw electrodes 120- 150 Celsius 3/32: 70-120 1/8: 90-160 5/32: 130-210 |
