Figure 6-3: Pulse Controls
The Pulse controls are used primarily to control heat input. Pulse offers a number of advantages as follows:
1) Control puddle – size and fluidity (especially out of position).
2) Increase penetration
3) Travel speed control
4) Better consistent quality
5) Decreased distortion on lighter or thinner materials
Pulse-current provides a system in which the welding current continuously changes between two levels.
During the periods of Peak current, heating and fusion takes place, and during the background (base) current
periods, cooling and solidification take place. Pulse Width is the time in one cycle the current remains at the
peak current setting. Pulse Frequency, measured in Hertz, is the number of cycles per second the current
travels between peak and background current settings. It is as if the foot rheostat were moved up and down
to increase and decrease the welding current on a regular basis. The faster you moved the foot rheostat up
and down the faster the frequency.
6.06 Save-Load Operation
A total number of 5 programs can be saved into the Transtig 300 AC/DC memory.
SAVE the Current Weld Parameters into Memory
• Press and HOLD the SAVE button. Beep will sound and digital display will show a number 1.
• Select a memory location by rotating the control knob, 1 to 5 is displayed on the meter.
• After selecting the desired memory location (i.e. 1 to 5), press the parameter button and the machine
will beep to confirm the weld parameters from the control panel are saved. The Save/Load bottons
must be depressed for 3 seconds to store settings.
LOAD (retrieve) a Program to Control Panel
• Press and HOLD the LOAD button. Beep will sound and digital display will show a number 1.
• Select a memory location by rotating the control knob, 1 to 5 is displayed on the meter.
• After selecting the desired memory location (i.e. 1 to 5), press the parameter button and the machine
will beep to confirm the weld parameters are loaded onto the control panel. The Save/Load bottons
must be depressed for 3 seconds to store settings.
