MIG COMPACT 220H/2R / 250H/2R / 290H/2R / 300H/4R / 350H/4R / 400H/4R
4 – I2 – Welding current – Only models 300/350/400 – When lighted indicates that welding current is showed on the
digital display.
5 – Digital display – Shows the selected parameter value. During welding:
- the digital display indicates the value of welding current A - Ampere (on digit versions)
- when the button is rotated the digital display shows the wire motor speed m/min
- after this adjustment automatically turns to indicate the welding current value.
6 – Adjustment button – Adjusts the selected parameter value.
7 – Spot mode – When selected, indicates that machine is at spot welding mode, automatically interrupting the welding
at the end of the selected period.
8 – 4 times mode – When selected indicates that machine is on 4 times torch mode. Under extensive welding seams,
the operator can press and release torch trigger; the machine continues to welding. Press and release button to stop
welding.
9 – 2 times mode – When selected indicates that machine is under 2 times torch mode. To continuous welding torch
trigger must be always pressed.
10 – Mode 2T/4T/Spot welding selecting key button.
11 – Selecting key button – Selects to adjust post-gas, spot, burn-back and up-slope time parameter.
12 – Post-gas – When selected allows adjusting, between 0 and 10 seconds, the gas flow time after stop welding; this
protects the welding seam from oxidation and cools the torch.
13 – Spot time: When selected the welding spot time. After this time the machine automatically stops.
14 – Burn-back – When selected allows adjust, between 0 and 10 seconds by means of the adjusting button, the wire
length at the torch, at the end of welding. The burn-back time can be adjusted between 0,1 and 1 second.
15 – Up-slope motor speed – When selected allows adjust, by means of the adjusting button, the up-slope speed motor
time till reach the selected speed. It must be adjusted between 0,1 and 1 seconds.
16 – Wire speed – When selected allows adjust, by means of the adjusting button, the wire speed between 0 and 18
m/min. This parameter is continuous active; with machine running, it's enough touch the button to adjust wire speed.
