Which of the following most accurately describes the problem?

From ESAB come two generalpurpose manual arc-welding electrodes for mild steel using dc or ac with low open-circuit voltage and a portable arc initiation and control unit for argon-arc welding for users of manual arcwelding plant.

The electrodes, Smoothtrode 43.23 and the Filletrode 43.33, give easy striking and re-striking making them suitable for tacking or intermittent welding. Smoothtrade 43.23 has a medium coating and is the easiest to use in all positions, says the company, while the Filletrode 43.33 with its heavier coating is recommended for downhand or HV fillet welding especially of thin plate.

Rods which are available in five diameters from 2.5mm to 6mm are 450mm long except for the 3.25mm and 2.5mm diameter ones which are 350mm long.

The Seirion control unit enables an arc to be established between electrode and workpiece allowing high-quality dc TIG welding to be undertaken

using any suitable droop, characteristic power source Csuc) as a transformer rectifier) witl. any ESAB airor water-coolec torches.

It can be used at the minimurr voltage setting at distances up tc 150ft from the power supply The argon flow adjustment car be carried out on the unit am

control of the heavy-duty con tactor and gas solenoid valvi prevents porosity caused b' -chatteringcontacts.

Weighing 14kg (31Ib) the uni measures 187.5mm by 390mn by 260mm, and uses an auxi liary input of 240 /110 /26V a 50HZ. The maximum weldim current rating is 300amp.
