DX (Deluxe) Models Additional Features

Dual schedule allows operator to switch between two welding parameters

without readjusting machine, eliminating downtime and enhancing quality.

Adjustable weld sequence control gives operator complete control

of the welding parameters: preflow, run-in, weld time, crater, burnback

and postflow.

Welding process range control locks parameters at a set percentage

of welding parameters to ensure welding procedures and quality

standards are maintained on the shop floor

Four weld programs allow the operators to store four independent

welding parameters reducing welding setup time. (Four programs

available per side on dual model.)

10 ft (3 m), 14-pin interconnecting cord for the

operator to hook up.

Automatic run-in control significantly improves

arc starting performance.

Trigger hold reduces operator fatigue by allowing

the operator to make long welds without having

to energize the trigger continuously.

DXA (Deluxe Aluminum) Model Additional Features

Setup to weld aluminum right out of the box. For optimum performance

on aluminum the DXA models are recommended. PD aluminum guides

and drive rolls are installed and the Bernard Q-Gun comes with the

proper size liner and plastic power pin tip installed, along with five

Bernard Centerfire contact tips. Weld sequence features allow superior

welds to be obtained.
