2. INTRODUCTION

2.1 GENERAL DESCRIPTION

WELDKAR TIG 1660 DC/HF
This lightweight Weldkar TIG DC inverter (7.0 kg) is
ideally suitable for maintenance, repair and production
work. With a mains voltage take-up of 230 Volt, this TIG
inverter is ideal for welding work on location and in the
workshop.
This 160 Amp TIG DC inverter is equipped with
HF ignition, 2 - 4 stroke, downslope and gas after
flow regulation. The stepless power adjustment in
combination with electronic display ensures extremely
accurate settings. The high welding duty of 60% at 160
Ampère guarantees long-term availability for intensive
welding work on steel and stainless steel. This Weldkar
1660 DC/HF is also equipped with an MMA function
for continuous welding of coated electrodes of up to
3.25 mm.
The 1660 comes with a handy, adjustable carrying strap
and is supplied complete in a solid case with accessories
including a 4-metre TIG torch, 4-metre earthing cable
with earth terminal, 2.5-mm TIG torch components and
4-metre welding cable with electrode holder.
The machine enjoys protection class IP 23 S (splash
waterproof) and EMC protection.
The weld inverter is supplied as standard with a:
- WK TIG 1660 DC/HF Inverter Power source
- Electrode holder with 4-metre welding cable and
DIN Plug
- Earthing terminal with 4-metre earthing cable and
DIN Plug
- TIG welding torch WP 17- 4 metres
- Shoulder strap
- Storage case
- Operating manual
The instructions below provide detailed information for
the correct and safe use of the machine and instructions
for obtaining the greatest efficiency and quality from
your power source.
IT MUST NOT BE USED TO DEFROST PIPES.

2.4 THERMAL PROTECTION

This inverter is protected by a thermostat. When the
thermostat is tripped, the machine stops delivering
current but the fan continues to run. The yellow led (5)
lights to indicate when it is tripped. Do not shut off the
welding machine until the led has gone off.

2.5 MOTOR-DRIVEN GENERATORS

These must have a power equal to or greater than KVA,
and must not deliver a voltage greater than 265V.
2.6 PROTECTION AGAINST SHORT-CIRCUITS
(ANTISTICK)
If a short-circuit occurs lasting more than two seconds
when welding with coated electrodes, the current is
reduced to harmless levels.
