GLW-180H —WELDER OPERATING INSTRUCTIONS

Welding Cables

The required cable welding size is governed by this simple rule:The longer the welding cable, or the greater the welding current, the thicker (copper strands) the calbe must be.

Select a welding cable with adequate thickness according to the cable length and welding amperage (current) as listed in Table 5.

Table 5. Welder Cable Sizes

	50	No. 3
	100	No. 3

Duty Cycle

The duty cycle for the generator/welder is based on 10 minute intervals. See Table 6 below.

Current	Less
Duty	100	80	60	50	40

CAUTION:

NEVER switch the current range selector switch during any welding operation.

1.Connect the welding cables (electrodes) to the generator's output terminals (Figure 4). For minimum welding current (min-130 amps), use an eyelet terminal connector with a 5/64" to 1/8" diameter, for maximum welding current (110 - max amps), use an eyelet terminal connector with a 3/32" to 5/32" diameter

2.Set the current regulator control switch on the control panel (Figure X) to the desired setting. The inner scale is for low current, the outer scale is high current output.

CAUTION: Figure 6. Current Regulator/Range Switches

To prevent serious accidents, ALWAYS turn off the generator/welder ( operation switch) and set the main circuit breaker to the OFF position.

3.Set the current range control switch (Figure 7) to either low or high. DO NOT change the position of this switch while welding.
